New verified APIs on PayAPI Market: week of 19 Oct 2026

Since 2026-10-14 we paid to verify 20 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.

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=crypto"

Those endpoints return only live listings, and by default only ones we have paid to verify.

The current catalogue

PayAPI Market lists 850 live APIs, of which 839 are settlement-verified, across 5 categories: Data, Finance, Intelligence, Tools, Verification.
