Use the experimental Edge Hunter endpoint to read the ranked sports markets shown on [the Edge Hunter page](https://0xinsider.com/sports/edge). Each row includes its game and market identity, the side backed by graded wallets, the measured backing, and current outcome quotes when available. This endpoint requires Max. A valid Pro credential returns `403 forbidden` with `error.reason: max_plan_required`. It replaces the retired sports signals and observations endpoints; it is a different response contract. ## Parameters | Parameter | Meaning | | - | - | | `horizon_hours` | Includes kickoffs after the snapshot's `as_of` and up to this many hours later. It defaults to 48 and is clamped to 1 through 48. | The board covers all sports with a fixed `B` grade floor, including `S`, `A`, and `B` wallets. It returns the first 30 ranked rows after the horizon filter. `total` counts the matching rows before that cap. ## Key response fields The response uses `object: "edge_hunter"`. Read the board from `data`, and the request metadata from `meta`. | Field | Meaning | | - | - | | `data.as_of` | The time the ranking snapshot was computed. | | `data.horizon_hours`, `data.min_grade` | The applied kickoff window and fixed `B` grade floor. | | `data.ranking_source` | `live` uses the current holder backing; `db_only` reports a fallback ranking from stored wallet positions. | | `data.directional_source` | `live` means the directional read ran; `degraded` means it failed. | | `data.cached_age_seconds` | The ranking snapshot's cache age, or `null` when computed for this request. | | `data.viewer` | Always `max` on this API endpoint. | | `data.free_rank` | Always `null`; there is no free signal row. | | `data.total` | The matching row count before the 30-row cap. | | `data.rows[].state`, `data.rows[].free` | Always `full` and `false`. | | `data.rows[].rank` | The row's rank within the returned window, starting at 1. | | `data.rows[].condition_id`, `event_slug`, `title` | The market and event identity. Optional identities can be `null`. | | `data.rows[].category`, `raw_category` | The canonical sport and provider category, such as `Soccer` and `EPL`. | | `data.rows[].game_start_time` | The known kickoff time. | | `data.rows[].volume` | The provider's cumulative traded volume in shares, not cash traded. | | `data.rows[].participants` | Participant names and available provider IDs, logos, colors, or headshots. | | `data.rows[].outcomes` | Both outcomes in provider order, with labels and current quotes when available. | | `data.rows[].signal` | The backed side, graded-wallet counts, backed dollars, backing share, ranking scores, and current quote. | `signal.sharp_pct` is a fraction, not a percentage: `0.81` means 81%. `signal.s_count`, `a_count`, and `b_count` count the backing wallets by grade; `graded_holders` is their combined count. ## Ranking and quote clocks A ranking snapshot and a current quote measure different things. `as_of` dates the ranking; each available `current_price` has its own `price`, `basis`, and `ts`. A kickoff can have passed by the time you receive a cached snapshot, so compare `game_start_time` with the current time before using the row. `price` is a decimal string. `basis` is `midpoint` or `last_trade`, and `ts` is an epoch-millisecond string for the observed quote state. `validated_at`, when present, is a separate epoch-millisecond string for the validation time. A missing quote is `null`. Do not substitute zero or treat the quote as the wallets' entry price. Read `ranking_source` and `directional_source` before presenting a fallback as current evidence. ## Example ```bash theme={null} curl -sS \ -H "Authorization: Bearer $OXINSIDER_API_KEY" \ "https://api.0xinsider.com/api/v1/edge-hunter?horizon_hours=24" ``` Use a Max API key or an authorized OAuth token. See [Authentication](/authentication). ## What it does not return * Observation cohorts, their funnel, or holder-arrival history. * Cursor pagination, a category filter, or a configurable grade floor. * Backed token IDs or category-skill evidence. * A guaranteed return, an executed entry price, or an order instruction. The retired paths are `/api/v1/sports-edge-signals`, `/api/v1/sports-edge-observations`, `/api/v1/sports/pre-game-sides`, and `/api/v1/sports/pre-game-side-observations`. All 4 return `410 endpoint_retired`. Update the response parser when migrating. ## OpenAPI ````yaml GET /api/v1/edge-hunter openapi: 3.1.0 info: x-generated-rate-limit-policy-from: web/src/lib/rate-limit-facts.ts via web/scripts/generate-api-policy.ts title: 0xinsider API description: >- Follow provider-exposed large-trade activity from Polymarket. Polymarket wallet-attributed trades can add grades, P&L, strategy, and diagnostic-score context when sufficient source data exists. Fields can be null or unavailable. Normal API requests use a 30-second server timeout that returns HTTP 408 Request Timeout with the standard error envelope (error.code request_timeout) when exceeded. Every /api/v1 failure answers that envelope, including a body that is not JSON or does not fit the request schema (400 invalid_body), a query or path value that does not parse (400 invalid_query, invalid_path), a missing Content-Type: application/json (415 unsupported_media_type), a body over 1048576 bytes (413 payload_too_large) and a method the path does not serve (405 method_not_allowed), each with error.param naming the field where one is known and meta.request_id equal to X-Request-Id. Unknown query names are ignored by default and reported in X-Query-Ignored, while X-Effective-Query lists the normalized names and values applied using form-urlencoded decoding, where + is a space; strict mode returns 400 bad_request with error.reason unknown_query_parameter before the handler runs, including for an unknown name with an incomplete percent escape. Every list operation clamps an out-of-range limit into its published minimum..maximum instead of refusing it (limit=0 reads one row, limit=500 reads the maximum), and X-Effective-Query reports the clamped value; only a limit that is not an integer is refused, with 400 invalid_query. Public REST /api/v1/* endpoints, excluding /api/v1/mcp, use Bearer-token based non-credentialed browser CORS: any Origin may call with Authorization, Content-Type, If-None-Match, Idempotency-Key, Mcp-Session-Id, Mcp-Protocol-Version, Last-Event-Id, and X-Query-Validation request headers. X-Query-Validation: strict opts into rejecting unknown query names; the default remains compatible. Remote MCP at /api/v1/mcp is non-credentialed, but still validates Origin against the 0xinsider/localhost allowlist per MCP Streamable HTTP DNS-rebinding guidance. Successful browser CORS preflight responses advertise Access-Control-Max-Age: 86400. Browser JavaScript may read RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, the legacy X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, Retry-After, ETag, X-Request-Id, X-Request-Cost, X-Usage-Accounting, X-Batch-RateLimit-Limit, X-Batch-RateLimit-Remaining, X-Batch-RateLimit-Reset, Mcp-Session-Id, X-Mcp-Error-Code, X-Query-Ignored, X-Effective-Query, Deprecation, Sunset, and Link response headers. Rate-limit headers describe the budget a request was counted against: the API key's per-minute window on an authenticated call, and the per-IP budget on a public route or on a refused credential (401, 402, 403, 423), so a client looping on a bad or lapsed key still sees how much room it has.

Credentialed first-party routes such as /api/keys, /api/billing, and auth endpoints remain restricted to configured 0xinsider origins. Protected V1 responses, except the zero-cost /api/v1/usage route, after handler execution carry X-Usage-Accounting: persisted, failed, or unknown. This reports the usage-record write; it does not change the handler result. Do not replay a successful mutation to repair an unknown usage record. Before execution, unavailable accounting capacity returns HTTP 503 with error.reason=request_accounting_unavailable; honor Retry-After. Public API responses add the browser-readable Server-Timing header: Processing time in milliseconds, for example api;dur=12.345. Includes API authentication, quota admission, handler work and response construction. Excludes network transit and streamed body or export-file transfer. The engineering budget is strictly below 250 ms; this header reports observations, not a latency guarantee or a new timeout. Requests through https://0xinsider.com/api/* append Server-Timing: web_api;dur= and X-Web-Request-Id for that web origin handler. The web clock includes upstream waiting and existing body construction, so do not add it to api;dur. It excludes platform routing, cold module initialization, CDN hits and later stream/file transfer. On a cache hit these headers describe the earlier origin fill, not the current request; static Markdown API routes have no fresh web clock. version: 1.0.0 contact: name: 0xinsider email: support@0xinsider.com url: https://0xinsider.com servers: - url: https://api.0xinsider.com description: >- Production (live data).

Three independent budgets. (1) 100 requests/minute per user (sliding window), on every authenticated route. (2) On the BATCH routes only: 2500 batch item units/minute per user, reserved before any item is executed. A batch with N requested items costs N item units, including duplicate and invalid items. 2500 = 100 requests x 25 items per batch, which is the most item work a key can buy through the request limiter at all: a caller may spend their entire 100-request minute on full 25-item batches without the item budget being what stops them. The REQUEST budget is the effective ceiling, and batching is never the more expensive choice. The item budget can still deny at a sliding-window boundary (both counters carry the previous window forward with a floor, and the item counter runs 25x the request counter), so honor a 429 from either. Over-quota batches return 429 with Retry-After plus RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset before any item work is done. (3) The monthly quota: Pro includes 500,000 and Max includes 2,000,000 authenticated requests per UTC calendar month. Over the plan's included requests: with pay as you go on, the excess bills at USD 0.20 per 1,000 on a monthly invoice, up to four times the included allowance (2,000,000 requests for Pro); without it, from October 1, 2026, the next request answers 429 rate_limited with error.reason monthly_quota_exceeded and a Retry-After to the month's reset. Pay-as-you-go accounts receive the same refusal at their ceiling. A refused request is not counted. Every authenticated response carries X-Monthly-Quota-Limit, X-Monthly-Quota-Remaining, and X-Monthly-Quota-Reset (unix seconds, the first of next month). (4) The per-address budget: 1200 requests/minute per IP, shared by every caller behind one address and counted before authentication, on every route. A 429 from it carries error.reason ip_rate_limited and describes that bucket in RateLimit-*; a throttled address (sustained over-limit traffic) carries error.reason ip_throttled with a Retry-After of minutes to days, and a request before it does not shorten the cooldown. Every 429 is the standard error envelope with meta.request_id equal to X-Request-Id. headers: Retry-After: description: Seconds until rate limit resets. schema: type: integer RateLimit-Limit: $ref: '#/components/headers/RateLimit-Limit' RateLimit-Remaining: $ref: '#/components/headers/RateLimit-Remaining' RateLimit-Reset: $ref: '#/components/headers/RateLimit-Reset' X-RateLimit-Limit: schema: type: integer X-RateLimit-Remaining: schema: type: integer X-RateLimit-Reset: schema: type: integer X-Request-Id: schema: type: string content: application/json: schema: $ref: '#/components/schemas/ApiError' '500': description: Unexpected server error content: application/json: schema: $ref: '#/components/schemas/ApiError' '503': description: >- Redis-backed authenticated rate limiter unavailable; retry after the per-process outage cooldown headers: Retry-After: description: >- Seconds until the middleware will probe the Redis-backed rate limiter again. schema: type: integer X-Request-Id: schema: type: string content: application/json: schema: $ref: '#/components/schemas/ApiError' security: - bearerAuth: [] - oauth2: - read components: headers: X-Query-Ignored: description: >- Comma-separated, percent-encoded query names the operation did not publish and therefore ignored in compatible mode.

The flag describes the READ, not its consequence: a read that ran and found nothing groupable also leaves the directional fields null, and that is honestly "live" -- the per-signal nulls already say "nothing to enrich here", so this snapshot-level flag carries only what they cannot, namely whether the read ran at all. A degraded response is cached on the shorter degraded TTL so it self-heals.

Present on every retryable error: `pick_not_released`, `rate_limited`, `rate_limit_unavailable`, and `read_model_warming`. Omitted otherwise. The absolute twin of `Retry-After`; prefer the header for the sleep duration. For `pick_not_released`, the earliest of the next scheduled release, the next automatic selector attempt, the operating-window start, or about 60 seconds.

The specific, actionable cause behind `code`, when there is one more specific than the code itself. `code` keeps its published values, so existing clients are unaffected; new clients branch on `reason`. Omitted when the code already says everything we know. pick_not_released: no Pick of the Day is published for the current product day; schedule one request against retry_at instead of polling. unknown_endpoint: the PATH is not a route on this API -- read GET /api/v1, do not retry. trader_not_tracked: the wallet is real and the URL is right, but the trader is not on the warm sync tier (the wallets we sync most often) -- stop asking for this wallet. cursor_expired: pagination went stale mid-walk -- re-request the first page and continue. read_model_warming: the requested endpoint cannot serve its read model yet; exact causes are endpoint-specific and can include a cold or contended refresh or a dependency that prevented refresh. database_unavailable: the API's database or its connection pool is temporarily unreachable (a connection-class failure, not a query fault); code stays rate_limit_unavailable, nothing is rate-limited, retry after Retry-After / retry_at. idempotency_in_progress: retain the exact Idempotency-Key and request body, then retry shortly. webhook_delivery_in_progress: retry the URL or signing-secret configuration change after the destination's active request completes. request_accounting_unavailable: accounting capacity is unavailable before the handler executes; retry after Retry-After / retry_at. sandbox_api_key: the credential is a sandbox key (oxi_sk_test_) from POST /api/v1/agents/register, which only the sandbox server accepts -- call the sandbox base URL with it, or get a live key or OAuth access token; do not retry it here. api_key_in_query: the key was sent as a ?token= query parameter, which no route reads because URLs land in logs and history; the key itself was not checked -- resend it as Authorization: Bearer. subscription_inactive: the key is valid but the account's Pro subscription has lapsed (402 subscription_required); permanent until a person reactivates at https://0xinsider.com/billing, which the message names -- stop retrying on a schedule and surface the link. The key owner is emailed once per lapse. monthly_quota_exceeded: the account has used the requests its plan includes for the UTC calendar month (429 rate_limited); retry_at and Retry-After name the first of next month, the only retry that can succeed, and the message names https://0xinsider.com/developers, where pay as you go for requests over the quota is turned on. The X-Monthly-Quota-Limit, X-Monthly-Quota-Remaining and X-Monthly-Quota-Reset headers on every authenticated response say how close the account is. invalid_query, invalid_path, invalid_body (400 bad_request, #16146): a query parameter, a path segment or the JSON body did not parse or does not fit the route's schema, so no handler ran; param names the field when the parser named one (a query key, a path segment, a JSON path such as traders[0], or body); fix the request, never retry it as sent. unsupported_media_type (415 bad_request, param content-type): send the body with Content-Type: application/json. payload_too_large (413 bad_request, param body): the body is over 1048576 bytes. method_not_allowed (405 bad_request): the path is a route but not with this method; the Allow header names the methods it serves. ip_rate_limited (429 rate_limited, #16380): the per-address budget every caller behind one IP shares, counted before authentication, is spent; not the key's own window, and the RateLimit-* headers describe that bucket. ip_throttled (429 rate_limited): the address is in a cooldown after sustained over-limit traffic; Retry-After is minutes to days, and a request before it does not shorten the cooldown. max_plan_required (403 forbidden, #23085): the key is valid and its account is on Pro, but the route is part of Max (GET /api/v1/edge-hunter); every Pro route keeps working with the same key, so do not disable it. The message names https://0xinsider.com/pricing, where the account upgrades; a retry never clears it. endpoint_retired (410): this legacy sports endpoint no longer serves data. Migrate to GET /api/v1/edge-hunter; retrying the retired path cannot succeed. meta: $ref: '#/components/schemas/ResponseMeta' EdgeHunterRow: type: object required: - rank - state - free - condition_id - event_slug - title - category - raw_category - game_start_time - volume - participants - image - outcomes - signal properties: rank: type: integer minimum: 1 state: type: string const: full free: type: boolean const: false condition_id: type: string event_slug: type: string nullable: true title: type: string nullable: true category: type: string nullable: true enum: - Basketball - Football - Baseball - Hockey - MMA - Boxing - Soccer - Cricket - Golf - Tennis - Esports - Racing - Table Tennis - Pickleball raw_category: type: string nullable: true game_start_time: type: string format: date-time nullable: true volume: type: number nullable: true description: >- Cumulative provider taker volume in shares, not cash in USD.
