Open data
What Settled measures, free to download and cite. The scout's purchase record is the part nobody else has: real x402 payments with their transactions and what came back, published 30 days behind. Everything here is CC BY 4.0: use it, cite "Settled (settled.tools)". The daily snapshot and every download are signed by Settled's key, so a copy can be checked against the original.
Scout purchases
Every real x402 purchase Settled's scout has made with its own USDC from 2026-10-01 up to 2026-10-14: 782 purchases from 782 endpoints, $7.93 paid, 744 delivered and 38 paid with nothing usable back. One row per purchase: when, the endpoint and its payout wallet, the amount, the transaction on Base, what came back (type, bytes, the delivery verdict) and whether it counted as delivered. The free record runs 30 days behind and grows daily; the last 30 days (4,223 more purchases, the newest today) are in the index export and, one endpoint at a time, in the free check.
Download CSV JSON ?since=YYYY-MM-DD narrows either one.
The scout is the wallet 0xA1d1C0cf717402ff3651aA4873CcF96410B01978; every row's transaction is on-chain, so the record can be checked without trusting Settled. A purchase counts as delivered when the paid answer matched what the listing promised (the delivery check described under Method on the Observatory); "paid with nothing usable back" is an error, an empty body or a placeholder after a settled payment. The record is what the scout bought, not a sample of the market: it buys from endpoints that quote a price it is allowed to pay, cheapest first, and re-buys where buyers look.

Payability sample
500 endpoints from the index with their status, payability, price, payout wallet and quality, a fresh random draw each day: sample.csv. The whole index, with each seller's 30-day on-chain demand, is the index export ($5, or a 30-day research licence for $49).
Daily signed snapshot
Every endpoint's state at the end of each UTC day, signed and chained to the day before, so a published number can be checked later: the latest snapshot, and /v1/snapshots/YYYY-MM-DD for any day.
Observatory
The weekly x402 Payability Observatory: how many listed endpoints an agent can actually pay, why the rest cannot, and what paid purchases delivered. The latest issue and 7 earlier ones; the figures as JSON at /v1/observatory/latest.
Venues
Which bounty and task venues pay agents, measured from their payout wallets, with the evidence behind each verdict: the venues page, or the signed JSON.
How to cite and verify
