Authorizations

​
X-API-Key
string
header
required

Issue from /v1/keys (or admin-issued for enterprise tier).

Headers

​
X-API-Key
string | null

Your PolySimulator API key

​
POLY_API_KEY
string | null

Polymarket-CLOB-compat alias for X-API-Key (underscore form). SDK clients ported from Polymarket can authenticate without changing header names. X-API-Key takes precedence when both are provided.

​
Poly-API-Key
string | null

PM-CLOB-compat dashed-form alias for X-API-Key. Same value semantics as POLY_API_KEY but with HTTP-conventional dash separators. Audit P1 (staging audit 2026-05-16 0817 PR #1296): the per-tier middleware accepts both spellings but the auth dependency originally only matched the underscore form — now both work end-to-end.

​
authorization
string | null

PM-CLOB-compat: Authorization: Bearer ps_live_... (or ps_test_...) is accepted as an alias for X-API-Key so py-clob-client and other ported SDKs authenticate without header name changes. Bearer JWTs are NOT accepted here — use the dashboard-auth endpoints for those.

Path Parameters

order_id
string
required

Response

Successful Response

Polymarket-shaped order row for GET /data/orders and GET /order/{id}. Subset of PM's full OpenOrder schema — fields we don't model (maker_orders, transaction_hash, trader_side, fee_rate_bps, on-chain hashes) are emitted as null so SDKs parsing fixed schemas don't break.
