overlay: 1.0.0 info: title: API Evangelist enhancements for LinqAlpha API version: 1.0.0 extends: openapi/linqalpha-openapi-original.json x-generated: '2026-07-19' x-method: generated x-source: openapi/linqalpha-openapi-original.json x-note: >- Captures API Evangelist's enrichment of the published LinqAlpha OpenAPI without mutating it. The largest real gap in the source document is missing operationIds: only 11 of 48 operations declare one, all of them under the Briefing tag. Every other operation must be addressed by method + path, which blocks Arazzo workflows, generated SDKs, and agent tool binding. That gap is recorded here rather than papered over — this overlay does not invent operationIds. actions: - target: $.info update: x-apievangelist-enriched: '2026-07-19' x-apievangelist-artifacts: authentication: authentication/linqalpha-authentication.yml scopes: scopes/linqalpha-scopes.yml conventions: conventions/linqalpha-conventions.yml errors: errors/linqalpha-problem-types.yml lifecycle: lifecycle/linqalpha-lifecycle.yml conformance: conformance/linqalpha-conformance.yml data_model: data-model/linqalpha-data-model.yml mcp: mcp/linqalpha-mcp.yml rate_limits: rate-limits/linqalpha-rate-limits.yml well_known: well-known/linqalpha-well-known.yml - target: $.info update: x-apievangelist-contract-gaps: - id: missing-operation-ids detail: 37 of 48 operations declare no operationId; only the Briefing tag supplies them. impact: blocks Arazzo authoring, SDK generation, and reliable agent tool binding - id: no-idempotency detail: no Idempotency-Key header or parameter on any write operation impact: retried creates may duplicate briefings, source batches, and connectors - id: non-standard-errors detail: errors use a vendor envelope rather than RFC 9457 application/problem+json - id: no-contact-or-license-url detail: info block declares license name MIT with no url and carries no contact object - target: $.servers update: - url: https://api.linqalpha.com description: Production - target: $.info update: x-apievangelist-auth-summary: rest: X-API-KEY header, global security requirement, unscoped mcp: >- OAuth 2.0 authorization_code with PKCE S256 and dynamic client registration, scope mcp:tools - target: $.info update: x-apievangelist-conventions: pagination: style: page-number params: - page - per_page streaming: text/event-stream on 7 operations async: fire-and-forget enqueue then poll versioning: uri-path, v1 and v2 coexist idempotency: not supported - target: $.components.securitySchemes.ApiKeyAuth update: description: >- Send your LinqAlpha API key in the X-API-KEY header on every request.
