Airscale rate limits are endpoint-specific. Each endpoint can enforce a different request limit and time window, so use the value documented on the endpoint page you are calling. ## Limits by endpoint All numeric limits below apply per workspace. A shared limit is one combined allowance for the named routes. | Endpoint | Rate limit | | - | - | | [Credit count](https://docs.airscale.io/api-reference/credit-count.md) | No endpoint-specific rate limit is documented. | | [Email finder](https://docs.airscale.io/api-reference/email-finder.md) | 3,000 requests per minute per workspace. | | [Bulk email finder](https://docs.airscale.io/api-reference/email-finder-\(bulk\)) | 3,000 input items per minute per workspace. | | [Mobile finder](https://docs.airscale.io/api-reference/mobile-finder.md) | 6,000 requests per minute per workspace. | | [Personal email](https://docs.airscale.io/api-reference/personal-email.md) | 2,000 requests per minute per workspace. | | [People URL finder](https://docs.airscale.io/api-reference/people-url-finder.md) | 6 requests per second per workspace. | | [People profile](https://docs.airscale.io/api-reference/extract-people-profile.md) | 3,000 requests per minute per workspace. | | [Company profile](https://docs.airscale.io/api-reference/extract-company-profile.md) | 3,000 requests per minute per workspace. | | [Domain to LinkedIn](https://docs.airscale.io/api-reference/domain-to-linkedin.md) | 180 requests per minute per workspace. | | [Reverse email](https://docs.airscale.io/api-reference/reverse-email.md) | 25 requests per second per workspace. | | [Reverse phone](https://docs.airscale.io/api-reference/reverse-phone.md) | 2,000 requests per minute per workspace. | | [Find people](https://docs.airscale.io/api-reference/find-people.md) | 6 requests per second per workspace. | | [Count people](https://docs.airscale.io/api-reference/find-people/count) | 6 requests per second per workspace. | | [Find companies](https://docs.airscale.io/api-reference/find-companies.md) | 6 requests per second per workspace. | | [Company filter values](https://docs.airscale.io/api-reference/find-companies/filter-values.md) | 6 requests per second per workspace. | | [Business intent topics](https://docs.airscale.io/api-reference/business-intent-topics.md) | 6 requests per second per workspace. | | [Company lookalikes](https://docs.airscale.io/api-reference/company-lookalikes.md) | 15 requests per rolling minute per workspace.

Find companies shares its **6 requests per second** with Company filter values and Business intent topics. These are separate limits for the two endpoint families. Post search, Profile comments, Comment likers, Profile posts, and Company posts each have their own 180-request allowance; they do not share it with each other or with Post likers and Post commenters. Company lookalikes returns `429` when its rate or concurrency limit is reached. Honor `Retry-After` when present. Repeating a search can cause another charge; see the [endpoint guidance](https://docs.airscale.io/api-reference/company-lookalikes.md). For bulk email, the allowance counts **input items**, not HTTP requests. An endpoint without a documented numeric limit should not be treated as unlimited; use bounded concurrency and handle `429` responses. ## Handle rate-limit responses When a request exceeds an endpoint's limit, the API returns `429 Too Many Requests`. Treat the status code as the rate-limit signal; do not depend on an error field or response header unless that endpoint page documents it. Only retry when the endpoint page says the operation is safe to retry. Use bounded exponential backoff: cap both the maximum delay and the total number of attempts, then surface a persistent `429` to your application. ## Check an endpoint's limit Review the request limit on the endpoint page before setting concurrency: > **[Find people](https://docs.airscale.io/api-reference/find-people.md)** > > People search limits and request contract. > **[Find companies](https://docs.airscale.io/api-reference/find-companies.md)** > > Company search limits and request contract. > **[Email finder](https://docs.airscale.io/api-reference/email-finder.md)** > > Professional email lookup limits and request contract. > **[Airsearch](https://docs.airscale.io/api-reference/airsearch.md)** > > Airsearch limits and request contract.
