Wellsaid Labs Rate Limits

WellSaid Labs publishes concrete API limits. A default API key is limited to 3 requests per second and 1,000 characters per request, on top of a unique total monthly character quota per account. Higher concurrency is available on request to WellSaid. Every response carries rate-limit and quota state on x-rate-limit-limit / x-rate-limit-remaining / x-rate-limit-reset and x-quota-limit / x-quota-remaining / x-quota-reset headers, so clients can self-throttle and track remaining monthly characters.

Wellsaid Labs Rate Limits is the machine-readable rate-limit profile for WellSaid Labs on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, measuring requests and characters.

Policies

Trusted Source Only
WellSaid does not currently support end-user authentication and recommends making API requests from an internal or trusted source rather than exposing the API key to end users.
Backoff Strategy
Clients should honor the x-rate-limit-* headers, self-throttle to stay under 3 requests per second, and apply exponential backoff with jitter on 429 responses.
Higher Concurrency On Request
Accounts needing more than 3 requests per second can request raised concurrency limits from WellSaid.
