5 new verified APIs on PayAPI Market

By · Published 2026-09-25 · Last updated September 25, 2026 · 2 min read

Since 2026-09-22 we have paid to verify a batch of new APIs on PayAPI Market. Here are five of them, and what each 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.

Where we can, a 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.
