4 new verified APIs on PayAPI Market
Since 2026-08-14 we paid to verify 4 new APIs on PayAPI Market. Here is what each one does and what the verification actually proved.
What "verified" means here
We do not take a provider's word for it. For every API on this list we sent a real payment in USDC on Base, from our own wallet, and checked that the response contained genuine data.
Each check uses an input the provider did not advertise, so a canned example response cannot pass. Where the underlying data is public, we compare the paid response against the original source field by field.

How an agent finds these
Every verified API is queryable as JSON. An agent does not need to read this post, or the website, to find them.
curl "https://payapi.market/agent/list"
curl "https://payapi.market/agent/search?q=property"
Those endpoints return only live listings, and by default only ones we have paid to verify.
The current catalogue
PayAPI Market lists 79 live APIs, of which 62 are settlement-verified, across 5 categories: Data, Finance, Intelligence, Tools, Verification.
