Paid verification
How it worksNo sponsored paid call yet.
Pay this endpoint once from your own wallet (Base USDC, up to $1.00) and we call it and record what came back. Your wallet pays the listed recipient directly; Agent Tools never holds funds. Sponsored checks prove delivery; they do not count as demand.
Quality grade
How grading works- ✓ Answers a real HTTP 402 challenge
- ✓ Publishes a /.well-known/x402 descriptor
- ✓ Payment address on record
- ✓ Settlement network declared
- ✓ Price declared
x402 readiness
Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here A, 74.6/100), which weighs availability, payability and on-chain demand. How the two differ
| Valid payment requirements | 10/10 | Payment requirements carry a payee, a mainnet network and a price. |
| Live 402 challenge | 20/25 | Endpoint reachable; its 402 challenge was seen earlier (144 ms). |
| x402 version | n/a | x402 version not observed yet. |
| Signed descriptor | n/a | No x402 standard defines a signed descriptor. |
| Uptime (30 days) | 15/15 | 32/32 probes succeeded over 30 days (100%). |
| Resource declaration | 10/10 | Declares 6 paid resource(s). |
| Verified identity | 5/10 | Publisher descriptor (/.well-known/x402 or OpenAPI) on record; claim this listing to verify domain control. |
| Freshness + modern flags | 5/5 | seen in a source within 7 days; declares x402. |
| Security declaration | n/a | Payment is the access control for an x402 resource. |

Before you sign: can this Base contract be paused, frozen, or have tokens minted by its owner, self-destruct, or delegate execution somewhere you have not seen? Returns the opcodes and selectors actually present in the deployed bytecode, resolves proxies and EIP-7702 delegated accounts to what reall

How completely could this Base contract be checked, and on what grade of evidence. Separates checked-and-clean from could-not-be-checked, which automated callers otherwise conflate. Explicitly not a safety score.

What a Base transaction costs right now, with the RPC provider and trust level behind the number, so a caller can tell a credentialed reading from a degraded one before pricing a transaction.

What a tracked Base token is worth right now, taken as the median of the deepest pools rather than one pair, returning the pools considered and the spread across them.
