Market identifier lookups can include open and closed results with closed="any". Add the literal to synchronous and asynchronous list_markets/list_events and their shared request builders. Preserve current defaults (None/omitted for markets, False for events); invalid SDK values and any without a supported market identifier raise the existing UserInputError before HTTP. Existing six identifier selectors are sufficient; oracle/event selector additions remain in their separate open PRs.

Contract: markets-tooling#2836. Verified the final diff/review, release v0.350.166, production promotion, live schema and safe list/keyset reads on 2026-10-15. any removes only the closed filter; existing visibility, active/archive and protocol defaults still apply.

Validation: Ruff lint/format, strict Pyright, non-integration pytest suite (3,246 passed) and uv build; representative sync/async HTTP serialization and public typing coverage. Independent read-only SDK/API review found no blockers.

Production caveat: /events/count is advertised by the service schema but returns 422 id is invalid; this SDK change uses only the functioning keyset routes.

Companions: documentation, TypeScript.

Note

Low Risk
Additive query-parameter API with validation-only client changes; defaults and bool behavior are unchanged.

Overview
Adds closed="any" on Gamma list_events and list_markets (sync/async public and secure clients) so identifier lookups can return open and closed rows without changing existing defaults (False for events, omitted/None for markets).

Introduces a shared ClosedFilter type (bool | "any"), _check_closed validation, and a client-side guard that list_markets(closed="any") must include at least one supported identifier (ids, slug, clob_token_ids, etc.); invalid values still raise UserInputError before HTTP. Docstrings and unit tests cover param serialization, the identifier rule, and typing.
