The real catalog of tools for AI agents

Verify blockchain timestamp proofs offline, or anchor a new one through ProofLedger.

Verify whether an official SEC filing supports a specific financial claim.

Verify whether a supplied public source currently supports one atomic factual claim.

Verify a public listing URL and return source-supported facts or explicit fail-closed states.

Verify an agent's advertised route, price, payment details, and schemas against its live endpoint.

One API, all things verified — control, delegation, human approval, anti-impersonation.

Stamp content with permanent, verifiable provenance. Hash locally, verify free forever.

Verify VerixID proof-of-existence records and optionally prove ownership.

Signed proof of web observations for AI agents: Ed25519 proof packets for any URL.

Verify signed ALEX Evidence Packages. Fails closed on signature or schema errors.

Notarize, e-sign, and verify identity with the Proof API. Unofficial; not affiliated with Proof.

Verify whether a local Agent or MCP runtime matches an approved artifact.

Verifiable random decisions, audit sampling, fair selection, and proof verification using QnEvt.

Signed, Bitcoin-anchored observations of AI training-data disclosure; verifies silence proofs, seals

Cryptographically anchored evidence for agents: verified run receipts, proof-gated settlement.

Prove a real, unique human performed an action; mint a signed, verifiable Proof-of-Human credential.

Cryptographic proof of wallet ownership in two steps, with no keys and no custody.

Verify Umbra bridge accountability proofs (signed receipts, checkpoints, Merkle inclusion).

Proof primitive for AI agents on MultiversX. Anchor file hashes on-chain as verifiable proofs.

Second opinion before an irreversible agent action; signed proofs, free verify, public ledger.
