Rate Limits & Errors
Rate limits, error codes, and HTTP status responses for the Fiscal.ai API. Understand usage tiers and troubleshoot integration issues.
Rate Limits
The Fiscal.ai API enforces rate limits to ensure fair usage and maintain service quality for all users.
Free Plan
| Limit | Value |
|---|---|
| Burst requests | 50 requests/minute |
| Daily requests | 250 requests/day |
| Company-level data access | 25 companies on the free plan |
When you exceed the short burst limit, the API returns a 429 status code:
{
"error": "Rate limit exceeded for free trial."
}
When you exceed the daily limit, the API returns a 429 status code:
{
"error": "Daily request limit exceeded for free trial"
}
Your limit resets at midnight UTC each day.
Paid Plans
Paid plans have higher rate limits based on your subscription tier. Contact our sales team for details on rate limits for your specific plan.

Best Practices
-
Cache responses - Financial data doesn't change frequently. Cache responses to reduce API calls.
-
Handle 429 errors gracefully - Implement exponential backoff when you hit rate limits.
-
Check for errors first - Always check the HTTP status code before parsing the response body.
-
Use company keys - Using
companyKeydirectly is faster than looking up by ticker/exchange.
