Wattwatchers Rate Limits

Wattwatchers REST API v3 (Mercury) rate limits are enforced per API key across two independent dimensions — Transactions Per Second (TPS) and Transactions Per Day (TPD) — and both AUTO-SCALE with the number of devices assigned to the key rather than being fixed per plan. The published limits are illustrative; the authoritative value for any key is always the value in the response headers, which are returned on every successful request. Limits can be raised commercially via a Wattwatchers account manager, and increases take effect immediately without resetting the running count.

Wattwatchers Rate Limits is the machine-readable rate-limit profile for Wattwatchers on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 2 rate-limit definitions, measuring requests_per_second and requests_per_day.

The profile also includes response codes documented for throttled.

Tagged areas include Rate Limiting, Energy Data, and Smart Metering.
