## How we measure

- Window: every call made through looot in the last 30 days, read 2026-11-11 08:23 UTC.
- Success rate: the share of calls the provider answered without an error. An empty answer (for example no email found) counts as an answer. It does not check that the data is right. Calls that failed on looot's side are left out.
- Median time: half of the calls answered faster than this, as looot measured them. A 95th percentile is not published yet.
- Minimum calls: an endpoint shows numbers from 10 calls, and a provider is ranked from 20 calls. Rows below that say "Not enough calls to rank".
- One row per provider: the provider's endpoint with the most calls for the job. Every endpoint is listed in the endpoints table.
- Price: what looot charges per call or per result, in US dollars, from a prepaid balance. No subscription and no credits.
- Cost per success: the price per call divided by the success rate. A per-result price depends on how many results a call returns, so it has no cost per success.
- Source: GET https://api.looot.ai/v1/public-catalog/<endpoint>?stats=1 for each endpoint, and the public catalog for prices and jobs.
