Open a combo returned by [Combo fills](/api-reference/endpoint/list-combo-fills) to inspect its market legs, recorded totals, and up to 100 latest taker fills. The route requires paid API access and returns the full detail payload. ## Parameters | Parameter | Description | | - | - | | `condition_id` | The combo's `condition_id` from a fill. It is `0x` followed by 62 lowercase hexadecimal characters. A malformed identifier returns `400`; a combo not recorded by 0xinsider returns `404`. | ## Key response fields | Field | Meaning | | - | - | | `data.access` | `full` for this paid API response. | | `data.combo.legs_known` | Whether the combo's leg definition has been recorded. `false` means its fills can be known before its legs are available. | | `data.combo.legs[]` | Each leg's outcome, result, and market details when available. A missing market is `null`. | | `data.combo.status`, `data.combo.status_reason` | The result of the combo's YES conjunction and any reason the result is unavailable. Neither is wallet P\&L. | | `data.combo.totals` | All-time taker fill count, USDC collateral volume, largest fill, and first and last fill times. It is `null` when no fill totals exist. | | `data.combo.totals.last_fill_price_yes` | The last taker fill's execution price expressed for the YES outcome, as a nullable decimal string. Its age is given by `last_fill_at`. | | `data.fills[]` | Up to 100 latest recorded taker fills, newest first. Shares, collateral, fees, and execution prices retain their decimal strings. | | `data.lifecycle` | Recorded splits, merges, redemptions, and compressions, with their amounts and latest event time. It is `null` until a lifecycle event has been recorded for this combo. | | `data.coverage` | Freshness and completeness for the recorded combo data. `lifecycle_lag_blocks` and `lifecycle_backfilling` describe lifecycle coverage separately. | A leg's `pick_price_daily` is a stored daily observation for that leg's own outcome. Read `pick_price_as_of` and `pick_price_age_days` alongside it; it is not a live quote. ## Example Keep the `condition_id` from a fill in `COMBO_CONDITION_ID`: ```bash theme={null} curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \ "https://api.0xinsider.com/api/v1/combos/$COMBO_CONDITION_ID" ``` ## What it does not return * More than the latest 100 fills or a continuation for the detail's fill array. * A current order book or an execution price for a new order. * A wallet's realized P\&L or proof that it won from a combo's `status` alone. * A lifecycle total of `0` when no lifecycle event is recorded. `data.lifecycle` is `null` instead. ## Caching Save the response's `ETag` and send it in `If-None-Match` on your next request. If the representation has not changed, the server returns `304 Not Modified` with no body. ## OpenAPI ````yaml GET /api/v1/combos/{condition_id} 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, and X-Effective-Query 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. Conditional GET: these operations return a weak ETag and answer If-None-Match with 304 Not Modified and an empty body: GET /api/v1/health, GET /api/v1/insider-radar, GET /api/v1/insider-radar/{id}, GET /api/v1/large-positions, GET /api/v1/leaderboard, GET /api/v1/leaderboard/trending, GET /api/v1/market/{condition_id}/candles, GET /api/v1/market/{condition_id}/flow, GET /api/v1/market/{condition_id}/intel, GET /api/v1/market/{condition_id}/snapshot, GET /api/v1/markets/explore, GET /api/v1/markets/sharp-money-flows, GET /api/v1/markets/smart-money-flows, GET /api/v1/pick-of-the-day, GET /api/v1/pick-of-the-day/archive, GET /api/v1/positions, GET /api/v1/sports-edge-observations, GET /api/v1/sports-edge-signals, GET /api/v1/trader/{address}, GET /api/v1/trader/{address}/context, GET /api/v1/trader/{address}/pnl, GET /api/v1/trader/{address}/position-timeline, GET /api/v1/traders/{trader}/position-timeline, GET /api/v1/large-trades, GET /api/v1/large-trades/history, GET /api/v1/large-trades/{id}, GET /api/v1/whale-trades, GET /api/v1/whale-trades/history, GET /api/v1/whale-trades/{id}, GET /api/v1/whale-trades/{id}/counterparties/executions, GET /api/v1/whale-trades/{id}/counterparties/executions/{execution_id}/makers. 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: >- Combo reads may be temporarily unavailable (code internal_error).

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. meta: $ref: '#/components/schemas/ResponseMeta' ComboDetail: type: object required: - access - combo - fills - lifecycle - coverage properties: access: type: string enum: - full combo: $ref: '#/components/schemas/Combo' fills: type: array maxItems: 100 items: $ref: '#/components/schemas/ComboFill' lifecycle: anyOf: - $ref: '#/components/schemas/ComboLifecycleStats' - type: 'null' coverage: $ref: '#/components/schemas/ComboCoverage' description: >- One combo with its newest 100 fills and all-time lifecycle totals. Paid API callers receive full access. ResponseMeta: type: object required: - request_id - cached - cost properties: request_id: type: string description: >- Unique request ID (req_ prefix). The same value as the X-Request-Id response header, the request's usage accounting row and its log lines. cached: type: boolean cache_age_s: type: integer description: >- Cache age in seconds. Omitted when the response was not cached, and also when it was cached but its age cannot be established (an entry stored before its cache carried a computed instant). Never a placeholder: an unknown age is reported as no value rather than as the cache TTL. cost: type: integer description: >- Advisory request weight (relative compute cost). 1 for simple reads; higher for heavier endpoints. Not a credit/price. ranking_generation: type: integer description: >- Committed PostgreSQL-owned leaderboard generation for the returned rows and cursor.

It is read in the same repeatable-read snapshot as the leaderboard rows and is not request time, cache write time, or row insertion order. directional_source: type: string enum: - live - degraded description: >- Which path produced the team-directional read on this response. Only present on endpoints that compute one (today: GET /api/v1/sports-edge-signals). "live" means the read RAN. "degraded" means it FAILED, so nothing was measured and the ranking fell back to raw conviction. 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. Reported SEPARATELY from ranking_source because the two degradations are independent -- a sharp-money DB miss weakens the ranking DATA, a directional failure removes a ranking WEIGHT -- and a consumer down-weighting a degraded response needs to know which input it lost. Omitted on endpoints that compute no directional read. ranking_source: type: string enum: - live - db_only description: >- Which ranking-data path produced this response. Only present on endpoints that can degrade a ranking (today: GET /api/v1/sports-edge-signals). "live" is the normal path (the current holder pile from the provider batch); "db_only" is the degraded fallback (a truthful but weaker trader_markets ranking) served when the live sharp-money ranking batch is unavailable (a sharp-money DB read failure, not a Polymarket outage) and cached on a shorter TTL, so a consumer can down-weight or skip it. Omitted on endpoints that never degrade. category_skill_source: type: string enum: - live - partial - degraded - unavailable description: >- Whole filtered snapshot category-evidence status before pagination.
