Pass `?cursor=` from a prior response's `next_cursor` to fetch the next page. Unlike the activity feed, the anchor behind the cursor is `(block_number, log_index)`; this endpoint's total order. A malformed `condition` combo condition id is a `400` naming the value; a well-formed one that matches nothing serves an empty `data` array, which is the meaningful zero-state. ## OpenAPI ````yaml https:/data-api.polymarket.com/v2/openapi.json get /v2/activity/combos openapi: 3.1.0 info: title: Polymarket Data API v2 description: >- The Polymarket Data API: wallet portfolios, trade and activity feeds, market state and ranked boards. ## Conventions every endpoint shares - **Envelope**: every response wraps its payload in `data` (paged routes add `pagination`). A documented miss is `data: null` or an empty list, never an error. - **Pagination is cursor-only**: follow `pagination.next_cursor` until `null`; `has_more` is exact, and there is no `offset` query parameter (sending one is a `400`). Cursors are signed, typed per endpoint, and opaque. The feeds (`trades`, `activity`, combo activity) are keyset walks, stable across concurrent writes; the boards, `holders` and most combo-position sorts are offset walks behind the opaque token, so a page taken across a data refresh can skip or repeat rows. Where a cursor binds its cohort (the boards, positions, combo positions), resuming bare is fine, restating the same values is fine, and contradicting them is a `400`. The `trades`/`activity` feed cursors carry only the seek anchor and page size (plus the sort direction on activity): re-send identical filters on every page, because changing one mid-walk re-anchors silently. - **Rate limiting**: `429` with `Retry-After` is the busy signal for heavy queries and pool saturation. A heavy query may first be queued briefly for a capacity slot; the `429` arrives only if that short wait ends unserved. Each caller also has a per-client request allowance, and bursts past it get the same `429` with `Retry-After` sized to the remaining wait. Retry after the given delay. - **Identifiers**: `condition` (aliases `condition_id`, `conditionId`) is the unified query key for on-chain 0x condition ids; `market_id` fields carry Gamma's own market ids; `event_id` takes Gamma event ids; `token_id` is the CLOB asset id (the key on `/v2/prices-history`). - **Params** accept both snake_case and camelCase spellings. - **Units**: bare `volume`/`size` values are **shares**; `_usdc` suffixed fields are USD; `taker_` prefixed volumes are one-side. - **Sentinels**: `outcome_index: 999` means the outcome could not be labeled; a missing or `null` numeric field means unavailable, never zero. - **Windows on `/v2/trades?user=` and `/v2/activity`**: an omitted or `0` `start` floors to three years back (`start=1` asks for full history); an omitted or `0` `end` is now plus one day. The other `/v2/trades` shapes ignore `start`/`end`: `condition`/`event_id` serve a fixed three-year window and the bare feed serves the rolling current-plus-previous month. Other windowed routes treat omitted/`0` bounds as unbounded; each documents its own rule. `/v2/prices-history` is the strict one, where a `0` bound is a `400`. - **Auth**: data routes take a bearer token in `Authorization` (the `AUTH_TOKEN` header is accepted as an alias). contact: name: Polymarket license: name: MIT identifier: MIT version: 0.1.0 servers: - url: https://data-api.polymarket.com description: Production - url: https://data-api-rs.stage.pmd.use1.polymarket.sh description: Staging security: - bearer: [] tags: - name: wallet description: >- Everything anchored on one wallet: positions (base and combos), portfolio value, PnL history, the profile card, trading volume, and token approvals.
