Rate Limits
API rate limits and usage quotas.
Rate Limits
Per-second, minute and hour windows are matched by key channel, tier and endpoint. Separate keys currently have separate counters. A wildcard rule does not create a shared budget across endpoints.
Credits
Billing can be per returned item or per successful action. Empty-result billing depends on that rule. Service levels are not fixed prices. Actual usage is reported in meta.credits_consumed.
💡
Read API rate limits and billingOn HTTP 429 / error.code=42901, wait for Retry-After and use bounded retries. Avoid concurrent retries and automatically replaying write operations such as outreach.
