Rate Limits

The default rate limit is 100 requests per second per API key. Limits apply per key, not per account, so test and live keys have independent budgets.

Response headers

Every response includes:

• X-RateLimit-Limit — the ceiling (currently 100)
• X-RateLimit-Remaining — requests left in the current 1-second window
• X-RateLimit-Reset — Unix timestamp when the window resets

Handling 429

When you exceed the limit, ParaSta returns:

HTTP/1.1 429 Too Many Requests
Retry-After: 1

Wait at least Retry-After seconds before retrying. Combine with exponential backoff for repeated 429s (1s, 2s, 4s, 8s, …).
