Stockdata Rate Limits

Rate limit and usage-quota definitions for the StockData API, captured from the published documentation and pricing page. StockData enforces a per-60-second rate limit (signaled via the X-RateLimit-Limit header family) and a daily request quota per subscription plan (signaled via the X-UsageLimit-Limit header family). The numeric per-minute ceiling is not published.

Stockdata Rate Limits is the machine-readable rate-limit profile for StockData on the APIs.io network, in the API Commons Rate Limits shape.

It captures 6 rate-limit definitions, across the free, basic, standard, pro, and pro-50k tiers, measuring requests_per_day and requests_per_minute.

Limit state is signalled in the limit and usageLimit response headers, and an exhausted limit returns HTTP 429.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Finance, Financial Data, Stock Market, Market Data, and News.

Policies

Throttle signaling
429 rate_limit_reached is returned for too many requests in the past 60 seconds; remaining requests are exposed on the X-RateLimit-Limit header family.
Quota signaling
402 usage_limit_reached is returned when the daily plan quota is exhausted; the limit and remaining requests are exposed on the X-UsageLimit-Limit header family.
Request counting
Each API call that accesses stock or currency data adds 1 request to daily usage (FAQ).
