Supply one selector scope, or omit selectors for the coverage overview; venue can narrow the results. Results distinguish catalog presence from analytical support and market-data availability. They disclose supported settlement conventions, history ranges, sampling intervals, freshness and service limits where applicable. A market may be known and have family membership while its payout analysis remains unsupported. Check coverage before selecting analysis inputs rather than treating missing support as a zero payout. See the [integration guide](/guides/coverage-versioning) for the workflow and interpretation of this response. ## OpenAPI ````yaml GET /coverage openapi: 3.1.0 info: title: Rook API version: 0.1.0-design description: Markets, settlement relationships, scenarios, payouts and market data. servers: - url: https://api.rook.pm/v1 description: Proposed API origin; not an assertion these operations are callable. security: - ApiKeyBearer: [] tags: - name: Reference data description: Events, unified markets and native-ID resolution. - name: Families and scenarios description: Family scope and versioned scenario columns. - name: Relationships and Combos description: Related-market discovery, selected-set inference and Combo interpretation. - name: Payouts and exposure description: Scoped per-unit payouts and stateless portfolio/candidate calculations. - name: Market data description: Current prices, history, L2 books, prints, statistics and published fees. - name: Fair values description: Future private customer estimates; not Rook forecasts. - name: Coverage and updates description: Supported capabilities and incremental semantic changes. paths: /coverage: get: tags: - Coverage and updates summary: Get coverage description: >- Check whether selected Rook markets, listings or a family support the capabilities your workflow needs.
