specification: API Commons Rate Limits specificationVersion: '0.1' schema: https://raw.githubusercontent.com/api-evangelist/interface-research/main/schema/api-commons.yml#/$defs/RateLimits provider: 73 Strings providerId: 73-strings created: '2026-08-05' modified: '2026-08-05' generated: '2026-08-05' method: searched reconciled: false tags: - private-markets - financial-data - rate-limiting description: >- 73 Strings fronts its APIs with Microsoft Azure API Management and publishes quantitative limits on the APIM product rather than in the API contract. The self-serve "Starter" product publishes an explicit quota; the approval-gated products publish none. Every product API signals throttling with HTTP 429, but no Retry-After or X-RateLimit-* response header is declared in any OpenAPI. sources: - https://api-accord-eut-73strings.developer.azure-api.net/developer/products?api-version=2022-04-01-preview - https://api-accord-eut-73strings.developer.azure-api.net/products responseCodes: throttled: 429 throttledDescription: Too many requests sent in a short period. The client is being rate limited. headers: retry_after: false rate_limit_headers: [] note: No throttling response headers are declared in any of the six OpenAPI documents. limits: - name: Starter product: starter scope: subscription metric: requests-per-minute limit_count: 5 timeFrame: minute notes: 'Published verbatim: "Subscribers will be able to run 5 calls/minute up to a maximum of 100 calls/week."' - name: Starter weekly quota product: starter scope: subscription metric: requests-per-week limit_count: 100 timeFrame: week notes: Hard weekly ceiling on the self-serve tier. One subscription per developer. - name: Unlimited product: unlimited scope: subscription metric: requests limit_count: -1 timeFrame: unlimited notes: 'Published verbatim: "Subscribers have completely unlimited access to the API. Administrator approval is required."' - name: 73 Monitor product: 73-monitor scope: subscription metric: requests limit: not published notes: Approval-required product bundling the Monitor platform APIs; no quota published anonymously. - name: Transaction Management product: transaction-management scope: subscription metric: requests limit: not published notes: Approval-required product for the Transaction Management System APIs; no quota published anonymously. policies: - name: Subscription-key scoping description: >- Limits are enforced per APIM product subscription, and the subscription key is associated with a User ID. Requests are additionally scoped by orgId/userId in the request body. - name: Backoff description: >- No Retry-After is returned. Clients should apply exponential backoff with jitter on 429. notes: >- 16 of the 23 published operations document a 429 response. The 504 documented on bulk transaction ingest leaves processing state indeterminate and there is no idempotency key, so a retry after a throttle or timeout on that operation should be preceded by a read. maintainers: - FN: Kin Lane email: kin@apievangelist.com
