-The API allows 1000 requests per minute per IP address. Your organisation may have its own lower rate limits. Every response includes `X-RateLimit-Remaining` and `X-RateLimit-Reset` (an epoch timestamp in seconds). When you receive a `429` response, read the `Retry-After` header and wait for that many seconds before retrying. See [Error Handling Patterns](/docs/developers/examples/common-workflows#error-handling-patterns) for a more complete retry strategy.
