Rate limits

Rate limits are enforced per API key using a Redis sliding window — separately for per-minute and per-day buckets.

Tiers

Tier	Per minute	Per day
Free	20 requests	500 requests
Pro	200 requests	50,000 requests

All new keys start on the Free tier.

Response headers

Every API response includes rate limit information:

Header	Description
`X-RateLimit-Tier`	Your tier: `free` or `pro`
`X-RateLimit-Limit-Minute`	Your per-minute cap
`X-RateLimit-Limit-Day`	Your per-day cap
`X-RateLimit-Remaining-Minute`	Requests remaining this minute
`X-RateLimit-Remaining-Day`	Requests remaining today

HTTP 429 response

When a limit is exceeded you receive:

json

1{
2  "statusCode": 429,
3  "error": "Too Many Requests",
4  "message": "Per-minute rate limit exceeded (20 req/min for free tier)",
5  "retryAfter": 43
6}

retryAfter is the number of seconds until the current window resets.

Tips

Check X-RateLimit-Remaining-Minute before batching requests.
Cache responses where freshness isn't critical (e.g. company profiles, GET /v1/market/sectors).
Contact support to enquire about Pro tier access.
