Every create route accepts `Idempotency-Key`; replaying one returns the original record with `200` where the first call returned `201`. `POST /v1/transactions` requires the header, because a duplicated transaction is a duplicated financial record. license: name: proprietary identifier: proprietary version: 0.1.0 servers: - url: https://qa.esectra.com description: Esectra QA Documentation security: [] paths: /v1/control/kyt/sources: get: tags: - Control summary: '`GET /v1/control/kyt/sources`.' description: >- # Errors Returns `401` when the caller is not authenticated and `503` when the feed store cannot be reached. operationId: list_sources_handler responses: '200': description: Source readiness content: application/json: schema: $ref: '#/components/schemas/SourcesBody' '401': description: No usable credentials '503': description: A backing store could not be reached security: - api_key: [] - session_cookie: [] components: schemas: SourcesBody: type: object description: Every source, with the deployment's freshness rule. required: - max_age_seconds - all_required_healthy - sources properties: all_required_healthy: type: boolean description: Whether every source the deployment requires is usable. max_age_seconds: type: integer format: int64 description: How old data may be before it stops counting, in seconds. sanctions_coverage: oneOf: - type: 'null' - $ref: '#/components/schemas/CoverageBody' description: >- Sanctions coverage for the OFAC list, when a publication is installed. sources: type: array items: $ref: '#/components/schemas/SourceRow' description: One row per source.
