Use this endpoint to browse markets without a search term. Each result includes the market identifier you need for its other API routes. If you know a word or phrase in the market's title, use [Search markets](/api-reference/endpoint/search-markets). ## Parameters | Parameter | Description | | - | - | | `sort` | The order of the list: `trending` (the default), `hot`, `expiring`, `large_trades`, `volume`, or `newest`. `large_trades` ranks markets by large-trade activity; `whales` is its deprecated spelling and returns the same order. | | `category` | Keeps only markets in this category, ignoring case. A bucket name such as `Basketball` matches every Polymarket category that folds into it, including NBA, WNBA, and NCAAB. A raw Polymarket value such as `NBA` resolves to its bucket. | | `status` | `active`, `closed`, or `all`. A market is `closed` once Polymarket has closed trading or it has resolved, and `active` otherwise. The default is `all`. | | `q` | A keyword to match against market titles, at most 64 characters before whitespace is trimmed. | | `platform` | Accepts `polymarket` and changes nothing. Polymarket is the only provider. | | `limit` | How many entries to return, from 1 to 48. The default is 24, and a value outside the range is clamped rather than refused. | | `cursor` | The `next_cursor` value from the previous response. Each page holds discovery entries, not raw market rows. | ## Key response fields | Field | Meaning | | - | - | | `type` | `group` or `standalone`. A `group` entry carries `event_slug`, `parent_title`, and up to 12 markets in `markets`. A `standalone` entry carries one `market`. | | `market.url_slug` | The slug of the market's page on 0xinsider. `market.slug` is Polymarket's own slug. | | `market.status` | `active` or `closed`. A market is `closed` once Polymarket has closed trading or it has resolved, and `active` otherwise. [Search markets](/api-reference/endpoint/search-markets) and [Get market live snapshot](/api-reference/endpoint/get-market-snapshot) label a market by the same rule. | | `market.freshness.price_status` | `available` or `unavailable`. Read it before you render `last_price`. `enrichment_status` says the same thing about the whale fields. | | `market.token_id_yes`, `market.token_id_no` | Polymarket's ids for the two outcome tokens, as decimal strings. Either is `null` when the market has no stored token id. | | `facets.categories[]` | One `value`, `label`, and `count` row per category present in the current result. The values are the same bucket names the `category` parameter takes, straight from Polymarket's own category data. | | `total` | How many entries match the filters. It is on the first page only, and cursor pages leave it out. | | `computed_at`, `fresh_for_seconds` | When the server computed this body, and how many seconds it stays good for (60). Subtract the age of `computed_at` from `fresh_for_seconds` to get the time left. | ## Example ```bash theme={null} curl -H "Authorization: Bearer $OXINSIDER_API_KEY" \ "https://api.0xinsider.com/api/v1/markets/explore?category=Basketball&status=active&sort=large_trades&limit=24" ``` ## What it does not return * A market with no whale activity, or a market with an empty title. Both are omitted of the list. * More than 12 markets for one event. The market 0xinsider picked to represent the event is always one of them. * A page of more than 48 entries. That is the ceiling on `limit`. * A `400` for a `cursor` it cannot read. Explore drops an unreadable cursor and serves the first page instead, so follow `next_cursor` rather than assuming every request moved you forward. * A second provider. Every row is a Polymarket market, whatever `platform` says. ## Caching Save the response's `ETag` and send it in `If-None-Match` on your next request. If the list has not changed, the server returns `304 Not Modified` with no body. `computed_at` and `fresh_for_seconds` are omitted of the `ETag`, so a body recomputed with the same data keeps the same `ETag`. ## OpenAPI ````yaml GET /api/v1/markets/explore 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.

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.
