Every agent-payable API.

ProvenPaid: on-chain evidence that an agent payment endpoint actually gets paid. Pass ?url=<endpoint>. Returns the endpoint's payment challenge (x402 v1/v2; MPP detected), price, network and receiving address, plus on-chain payer depth: distinct payers, repeat-payer share and concentration, with coverage and methodology. Not charged for invalid or unsafe URLs.

What exactly does this provider support, where is it licensed and what does it charge? Full cited record for one provider: stablecoin rails, corridors, licences, published fees, coverage, developer and agent-payment support. Every fact has source URL, retrieval date, quote and confidence.

Provider trust and domain verification API — inspect public DNS/IP, HTTPS/TLS, first-party organization identity, social identities, and webpage evidence for a public domain.

A satledger workspace and the units of recording you pay for, from 0.50 upward. One unit is one recorded event; an anchor costs 100. Exports and reads are free. Returns an API key on payment.

Reads the EIP-1967 proxy slots live: is the contract upgradeable, what's the current implementation, and WHO can upgrade it. Flags the dangerous case — an EOA admin that can swap the logic at any block with no timelock/multisig. Upgradeability is a rug vector static scans miss.

Detect whether a contract is an upgradeable proxy and resolve its implementation: reads the standard EIP-1967 implementation/admin/beacon slots, EIP-1822 (UUPS), the OpenZeppelin legacy slot, and EIP-1167 minimal-proxy bytecode. Returns the proxy type, implementation, admin and beacon addresses when present. Reads live on-chain data with automatic endpoint fallback.
