Explore is Polymarket-only: the platform parameter is accepted for backward-compatibility but every request returns Polymarket markets. Paginates visible discovery entries rather than raw market rows, returns live category/platform facets alongside grouped event clusters or standalone markets, and includes total on the first page only. Categories come straight from provider metadata (Polymarket Gamma) and facets are flat value/label/count rows. Browse whale-active markets. This is the "what's going on right now" feed, already filtered to titled, user-facing markets with real activity. Omit `q` for the full feed, or pass it to narrow by keyword. Grouped events (e.g. "Next US president by candidate") return one row per event with a primary market injected, so you always have something to link to. Common filters: * `q=bitcoin`: keyword search against market titles. * `category=crypto`: restrict to a category. * `platform=polymarket` or `platform=kalshi`: restrict to one platform. * `status=active`: exclude resolved markets. * `sort=volume`: sort by recent volume. ```bash theme={null} curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \ "https://api.0xinsider.com/api/v1/markets/explore?category=crypto&status=active&limit=20" ``` Cursor-paginated.

Every wallet graded, every trade scored, every outlier flagged. API exposes trader grades, whale trades, smart money signals, and insider detection for AI agents, trading bots, and research tools. Normal API requests use a 30-second server timeout that returns HTTP 408 Request Timeout with an empty body when exceeded. 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, and Mcp-Session-Id request headers. 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 X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, Retry-After, ETag, X-Request-Id, X-Request-Cost, X-Batch-RateLimit-Limit, X-Batch-RateLimit-Remaining, X-Batch-RateLimit-Reset, Mcp-Session-Id, and X-Mcp-Error-Code response headers. Credentialed first-party routes such as /api/keys, /api/billing, and auth endpoints remain restricted to configured 0xinsider origins. 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).

Not a credit/price. 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 smart-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 smart-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.

Present on every retryable error (reason=pick_not_released, code=rate_limited, code=rate_limit_unavailable, reason=read_model_warming) and omitted otherwise. Always in the future. For pick_not_released it has two regimes: before the 11:00 UTC operating-window start, before a selected pick's stored release, or after a terminal skipped day, it is an exact floor and nothing can publish first. When a publish is overdue or the selector is still hunting inside the operating window, it is a bounded cadence (~60s), not a lower-bound promise; a pick may publish before it. Schedule one request and do not poll. Prefer Retry-After for the duration because it is immune to client clock skew. reason: type: string enum: - cursor_expired - unknown_endpoint - pick_not_released - trader_not_tracked - read_model_warming nullable: true description: >- ADDITIVE (#7209). 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 outside the HOT/WARM sync tiers -- 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. Consult that endpoint's contract, retry only this route after the interval, and do not infer dependency health from this reason. meta: $ref: '#/components/schemas/ResponseMeta' ExploreMarket: type: object required: - id - condition_id - title - status properties: id: type: string condition_id: type: string title: type: string minLength: 1 description: Non-empty market title. slug: type: string nullable: true description: Provider-native market slug. url_slug: type: string nullable: true description: First-party market page slug used for internal links. image: type: string nullable: true icon: type: string nullable: true category: type: string nullable: true platform: type: string nullable: true status: type: string enum: - active - closed volume: type: number nullable: true liquidity: type: number nullable: true whale_trade_count: type: integer nullable: true whale_distinct_wallets: type: integer nullable: true whale_total_usd: type: number nullable: true whale_last_trade_at: type: string format: date-time nullable: true end_date: type: string format: date-time nullable: true created_at: type: string format: date-time nullable: true outcome_yes: type: string nullable: true token_id_yes: type: string nullable: true description: >- The Polymarket CLOB token id (ERC1155 asset id, decimal string) for the YES outcome; null when unavailable (e.g. Kalshi markets, unsynced markets). outcome_no: type: string nullable: true token_id_no: type: string nullable: true description: >- The Polymarket CLOB token id (ERC1155 asset id, decimal string) for the NO outcome; null when unavailable (e.g. Kalshi markets, unsynced markets). event_slug: type: string nullable: true kalshi_series_slug: type: string nullable: true smart_score: type: number nullable: true smart_count: type: integer nullable: true smart_label: type: string nullable: true outcome_yes_label: type: string nullable: true description: >- Display label for the YES/outcome_index=0 side, enriched from provider outcome metadata when available. outcome_no_label: type: string nullable: true description: >- Display label for the NO/outcome_index=1 side, enriched from provider outcome metadata when available. outcome_yes_provider_id: type: integer nullable: true description: >- Provider-owned YES/outcome_index=0 identifier when available for trade-ticket wiring. outcome_no_provider_id: type: integer nullable: true description: >- Provider-owned NO/outcome_index=1 identifier when available for trade-ticket wiring. open_interest: type: number nullable: true oi_change_pct: type: number nullable: true price_points: type: array nullable: true items: type: array minItems: 2 maxItems: 2 items: type: number no_price_points: type: array nullable: true items: type: array minItems: 2 maxItems: 2 items: type: number last_price: type: number nullable: true no_last_price: type: number nullable: true change_pct_24h: type: number nullable: true no_change_pct_24h: type: number nullable: true discover_score: type: number nullable: true description: >- Backend-owned deterministic market discovery score used by the hot sort. score_components: type: object required: - missing_price_penalty properties: volume_signal: type: number nullable: true whale_signal: type: number nullable: true liquidity_signal: type: number nullable: true recency_signal: type: number nullable: true smart_money_signal: type: number nullable: true price_move_signal: type: number nullable: true missing_price_penalty: type: number freshness: type: object required: - enrichment_status - price_status properties: enrichment_status: type: string enum: - available - unavailable price_status: type: string enum: - available - unavailable responses: BadRequest: description: Invalid request parameter content: application/json: schema: $ref: '#/components/schemas/ApiError' Unauthorized: description: Missing or invalid API key content: application/json: schema: $ref: '#/components/schemas/ApiError' SubscriptionRequired: description: Active Insider subscription required content: application/json: schema: $ref: '#/components/schemas/ApiError' Forbidden: description: Account access denied content: application/json: schema: $ref: '#/components/schemas/ApiError' RequestTimeout: description: >- Request exceeded the server's 30-second transport timeout.

(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 still denies 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 before any item work is done. headers: Retry-After: description: Seconds until rate limit resets. schema: type: integer 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' RateLimitUnavailable: 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' securitySchemes: bearerAuth: type: http scheme: bearer description: >- API key authentication.
