Rate limits

Core API limits cap how many requests your organization can have in flight at once. Plan limits give the concurrency for each plan. Organizations created before concurrency limits keep per-minute limits per API key; the dashboard shows which limit applies to you.

Bucket	Scope	Limit
Core data APIs	Organization	Plan concurrency; each in-flight request uses one slot until its response finishes.
Core data APIs on per-minute plans	API key	Plan allowance per minute; most calls weigh 1, Crawl weighs 10.
Batches	Organization	1,000 units per minute; submit weighs 50, other calls 1.
Monitors	Organization	1,000 requests per minute.
Webhook deliveries	Organization	600 requests per minute.
Request logs	Organization	60 requests per minute.
Agent feedback	Organization	10 requests per minute.

All keys in an organization share its concurrency limit and credit balance. On per-minute plans, each key has its own core rate window. Management limits apply across the organization on every plan.

Headers and 429

A request that arrives while every concurrency slot is in use returns 429 with these headers:

X-RateLimit-Limit: 10
X-RateLimit-Remaining: 0
X-RateLimit-Mode: concurrency
Retry-After: 1

Wait for one of your in-flight requests to finish, or at least Retry-After seconds, before trying again. On per-minute plans, a rate-limited request returns:

X-RateLimit-Limit: 200
X-RateLimit-Remaining: 0
X-RateLimit-Reset: 1790470860
Retry-After: 12

X-RateLimit-Reset is a Unix timestamp in seconds. Per-minute retry delays range from 1 to 60 seconds. Size your worker pool to your concurrency limit, and add jitter to retries. Missing or invalid credentials can also trigger authentication protection; fix credentials instead of increasing retry traffic. Concurrency caps for batches and the number of monitors are separate from these request limits.
