X-API-Key
string

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. Both spellings are accepted 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.
