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: Hamming AI providerId: hamming-ai created: '2026-06-21' modified: '2026-06-21' reconciled: false tags: - AI - Voice Agents - LLM - Testing - Evaluation - Observability - Rate Limiting - Quotas - Throttling description: >- Hamming AI does not publish explicit REST API rate limits. Practical limits are governed by account/plan terms and by voice testing concurrency (Hamming advertises load testing up to 50K+ concurrent test calls on appropriate plans). Per-endpoint request quotas are not publicly documented and are not reconciled in this artifact. notes: >- Confirm any per-key request limits, concurrent call/test-run limits, and burst behavior with Hamming during reconciliation; values likely vary by plan and are not published. sources: - https://docs.hamming.ai - https://hamming.ai/ responseCodes: throttled: 429 limits: - name: REST API Requests scope: account metric: requests limit: see provider documentation notes: No public per-endpoint request rate limit is documented. - name: Concurrent Test Calls scope: account metric: concurrent_calls limit: up to 50K+ on supported plans notes: Load testing concurrency advertised by Hamming; actual ceiling depends on plan. - name: Voice Experiments scope: account metric: experiments limit: see provider documentation notes: Governed by plan/volume terms rather than a published quota. policies: - name: Plan-Based Limits description: Limits and concurrency scale with the account's plan and volume agreement. - name: Backoff Strategy description: Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses. maintainers: - FN: Kin Lane email: kin@apievangelist.com
