The real catalog of tools for AI agents

Fact-check AI answers with cited sources. Pay per call in USDC on Base via x402.

Grounding/hallucination guard: verify a claim against evidence (Supported/Refuted/NEE).

Verify multi-hop relational claims before an agent asserts them — zero tokens, with proof paths.

Paid claim verification with cited web evidence, source provenance, snapshots, and hashes.

Experimental GDPR grounding: rules, preconditions, exceptions, exact quotes, and citation checks.

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

Verifiable Earth ground truth for AI agents: water, hazard, ground stability, resource, with proof.

Zero-dependency verifiable-claims MCP: validate safely, verify with allow_execution, self-test.

Check that a source really says what your claim says, before you publish. Verbatim, multi-path.

Execution-grounded verification for AI coding agents on Windows: evidence, not agent claims.

Evidence-backed web verification for agents with deterministic JSON, text evidence, and screenshots.

Keep AI answers fresh with free source previews, scheduled monitoring, evidence history, and alerts.

Verify artifacts, hand off public state, and record, check and find evidence about capabilities.

Cite the claim, not the paper: 5,033 assertions, each hash-verifiable against its source PDF

Dated, signed compliance-evidence packs: gov-fact-grounded claims + exclusion screens + trap-facts.

Accounts-payable exception environment with a pass/fail verifier and proof packet: AI agents work AP

Verify claims, resolve FIGI identity, extract claims, and sign x402 delivery receipts over MCP.

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

Web search and AI answers with real source citations and a confidence score.

Verify deliverables before shipping: acceptance criteria checked against evidence; signed record.
