Before your agent negotiates or shares data with another agent, make both prove they qualify. Open a channel with on-chain conditions (hold 1,000,000 USDC, hold a governance token, carry a verified attestation). Every agent proves wallet control and is checked on live chain state across 34 chains, with a signed result anyone can verify offline, optionally with Merkle proofs. Re-check on demand; wh

GSC's payment door — a real one-cent settlement on Base, signed receipt returned. Prove your agent's payment stack here.

Timestamp and notarize any file or data by its SHA-256 hash: blockchain proof of existence and document integrity, anchored on Polygon in minutes and attested on Bitcoin (OpenTimestamps); blockchain notarization, not a notary act. Returns proof_id, certificate, proof.json and evidence ZIP, verifiable without Sellat. Use when you must prove that exact data existed by now and is intact.

Agent guardrail decision engine. Call once before every agent action; returns a single decision — proceed, slow down (with a reason and wait time), or stop — based on cost budget, chain depth, step cap and retry budget, and request volume pressure. Policy thresholds are configured separately via /policy; this endpoint only reports the decision for a single action.

Check whether a mined Base transaction did what your agent meant it to do. Fetches the receipt, decodes its ERC-20, ERC-721 and ERC-1155 transfer and approval logs, and reports each declared movement as matched, missing or short, with the observed amount beside the expected one. Catches reverts, success with no effect, fee-on-transfer skims and transfers to recipients you never named. Returns unkn

Profile a Base address in one call instead of four to six lookups. Returns contract or externally owned plus code size, proxy detection across all seven slot layouts including the legacy OpenZeppelin slot Base USDC uses, the resolved implementation, ERC-165 and behavioural ERC-20 detection, token metadata, requested ERC-20 balances, and denylist hits. Answers unknown rather than guessing, and null

Asks every known facilitator what it supports and measures how long that answer takes. Reachability, supported chains, supported assets, supported schemes and the current response time are measured live on every call. Limits, and they are the important part: error rate over 24 hours, uptime over 7 days and latency percentiles CANNOT be delivered. They require a series of own measurements every few

Checks whether an XRP Ledger token issuer is who it claims to be: two-way domain verification (on-ledger Domain field against the domain's xrp-ledger.toml), tokens issued and outstanding, and control flags such as freeze, clawback, blackholed, and multisign. Useful before accepting or holding a token.

On-chain state of ALST, the alest.io token for a tokenized Tesla Cybercab robotaxi (real-world asset). Name, symbol, decimals and total supply read live from Base Sepolia testnet.

Launch provenance check for LONG.xyz / Doppler tokens on Robinhood Chain — one call verifies a token against the on-chain Doppler Airlock registry: registered launch or not, which stock token backs it (and whether that numeraire is an official Robinhood stock token), launching integrator (LONG primary vs other launchpads vs suffix imitators), factory creator match, 1e18 vanity suffix, governance b
