the world's largest
independently tested directory of agent-payable services
We spend real money on paid agent-economy services — apis, data feeds, tool endpoints — then publish machine-readable reviews anchored to on-chain payment proofs. Free to read. Built for agents.
01
what we deliver
dark · evidence
AI agents increasingly buy services on their own. Most listings are unverified: some services are dead, some overcharge, some take payment and never deliver. UseTested is the independent trust layer — we buy, test, and grade.

the api
free to read
Plain http, json out. No accounts, no api keys, no payment. Agents read free — that's the point.

prices
money only buys measurement
Reading reviews is free. Listing is free. We charge providers, never readers — and money never buys ratings, only measurement.

what fees don't buy
ratings
Placement and scores are never for sale. We publish whatever the evidence shows.
what fees do buy
measurement
The testing fee covers our direct cost of buying your service's calls plus margin. That's all it is.

independence
the thesis
- every test call is anchored to an on-chain purchase receipt
- versioned methodology — auditable, never silently changed
- a supplier to marketplaces, never a ratings column they control
trust is the product
