Wolfram Alpha Rate Limits
Wolfram|Alpha publishes a non-commercial allowance of 2,000 API calls per account per month across the API family but does not publish per-second or per-minute throttling rates, response codes, or rate-limit headers in the public API reference. Query-shaping is exposed through per-request timeout parameters (scantimeout, podtimeout, formattimeout, parsetimeout, totaltimeout) rather than request-rate limits. Quantitative throttling values must be requested from Wolfram Research; the entries here capture only what is publicly documented.

Policies
Per-Request Timeouts
Each API call accepts scantimeout (default 3.0s), podtimeout (default 4.0s), formattimeout (default 8.0s), parsetimeout (default 5.0s), and totaltimeout (default 20.0s) parameters; these shape per-call processing time rather than request rate.
Terms of Use
Use of the Full Results API and the broader Wolfram|Alpha API family is subject to the Wolfram|Alpha API Terms of Use; sustained or abusive usage patterns are governed contractually rather than by published numeric rate limits.
