A search of the complete published documentation corpus returns no X-RateLimit-*, no RFC 9331/9440-style RateLimit-*, and no Retry-After. The only rate-limit language in the corpus refers to the Usage Limit POLICY on Smart Sessions — an on-chain constraint on how often a delegated agent may act — which is a different mechanism from transport throttling and must not be read as one. The consequence for an agent is that there is no runtime budget signal at all: it cannot know how close it is to a limit and can only discover exhaustion by being refused. checked: '2026-08-24' 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: Biconomy providerId: biconomy created: '2026-05-25' modified: '2026-05-25' reconciled: false tags: - Rate Limiting - Account Abstraction - MEE description: >- Documented rate-limit posture for the Biconomy Supertransaction API. Specific quantitative RPS/quota numbers are issued per project from the Biconomy Dashboard and are not published as a fixed rate card. Sponsorship policy limits (per-tx USD cap, per-user / per-day caps, allowed contracts, chain whitelist) are configured per project and enforced before /v1/quote returns a sponsored quote. sources: - https://docs.biconomy.io/overview/supertransaction-api - https://docs.biconomy.io/gasless-apps/sponsorship - https://dashboard.biconomy.io algorithm: token-bucket responseCodes: throttled: 429 quotaExceeded: 402 unauthorized: 401 forbidden: 403 limits: - tier: Developer surface: /v1/quote rpm: dashboard description: Per-API-key request rate on quote composition.
