Screen a crypto wallet address against sanctions lists

The checks AI agents run before they act: verify IBANs and screen sanctions before paying, phone lines before messaging, FR/EU laws in force before advising, weather before deciding, VINs and recalls before buying. Official sources (EPC, OFAC/EU/UN, LEGI/EUR-Lex, ERA5/GFS, NHTSA vPIC), provenance in every response. You only pay for answers.

Api Notarize Batch

Notarize AI output in bulk: one signed Ed25519 attestation of the model response per record for up to 20 AI inferences in a single call — same content hash, receipt token, and anchor status as single notarization, giving you a cryptographic receipt for inference across an entire audit-trail pipeline.

ForgeMesh Labs

Verify Redirect

Redirect tier (deterministic, no LLM): verifies where a public URL actually leads: final URL (byte-exact), first response status, and hop count of the HTTP chain, walked twice with per-hop SSRF checks. Use it to confirm a link or a moved page points where it claims. Loops and unstable chains return unverifiable, never a guess. First 100 checks per client are free: resend with header X-Use-Free-Allowance: yes and no payment to use them.

Api V1 Evidence Eventid

Evidence Pack for one event: source-passage excerpts with locators, the retrieval timestamp, sha256 snapshot hash, and a freshness/provenance verification status.

Api X402 Seal

AI Action Receipts: seal the HASHES of an AI action (input/output as hashes; your action label + meta are published) into GBLIN's signed append-only transparency log. Portable receipt: Ed25519 signature + RFC 6962 inclusion proof + C2SP signed checkpoint; root anchored daily on Base (EAS). Proves existence and time — not a compliance certificate. Free reads + demo: gblin-mcp.gblin-mcp-worker.workers.dev/log. Offline verifier: github.com/gblinproject/gblin-treasury-risk-regime

GBLIN

Notarize

Notarize a public URL: we fetch it ourselves and return a signed snapshot (final URL, HTTP status, content-type, sha256 of the body, server timestamp, upstream host) with TWO cryptographic attestations — a plain EIP-712 signature and an EAS off-chain (Version2) attestation. Proves what this endpoint observed at fetch time (integrity + timestamp + non-repudiation). mode=hash (default) returns metadata + hash only; mode=full also returns the body.

V1 Eu Company Check

One-call verification of a European company: official registry existence and status, insolvency signals, VAT (VIES), LEI (GLEIF), sanctions screening (EU/OFAC/UN/UK/FR), EORI and domain age, condensed into a pass/review/fail verdict with per-check source, timestamp and an explicit coverage map. Query: country=FR (FR, UK, IE, NO, FI, SK, PL, CZ, CH) and id=552032534 (national registry number). Factual verification, not a credit score. Buyers are never charged on failure.

Create a cryptographic attestation

KHOTEM is a cryptographic witness for AI agents: seal (SHA-256 commitments), attest, verify, timestamp and audit, plus three paid operational-law documents for agent builders. x402 v2 with EIP-712-ready accepts on Base, Polygon and Solana. Direct on-chain USDC verification — no facilitator, no accounts, no API keys. Pay per request, present the settlement txHash in X-PAYMENT. Machine-readable via OpenAPI, Bazaar discovery extension, skill.md, AGENTS.md and llms.txt.

Verify Json

JSON tier (deterministic, no LLM): verifies a claimed value lives at a named JSON path in a public endpoint's response, by independent double re-fetch. Use it for machine-readable API responses; for HTML pages use /verify. Claim keys are paths (data.items[0].price). Type-strict; volatile values return unverifiable, never a guess. Public HTTPS JSON only. First 100 checks per client are free: resend with header X-Use-Free-Allowance: yes and no payment to use them.

V1 Notarize

Anchor an AI agent decision or audit record to Base mainnet. Submit {schema, payload_hash (SHA-256 hex, 64 chars), metadata}; service queues into a Merkle batch and returns a receipt with pending_anchor status immediately. Full Merkle proof and on-chain anchor_tx available via free GET /v1/notarize/:receipt_id after batch anchors (within batch_threshold receipts or 120s).

Signed web observation

Independent point-in-time observation of a public URL, signed with ed25519. Fetches the URL from a neutral third-party host and returns HTTP status, final URL after redirects, sha256 of the exact bytes received, size, and cache headers — plus your chosen check (exists / contains a string / content hash). Useful when an agent needs a durable, verifiable record that a page said something at a specific moment.

Verify Presence

PRESENCE tier (deterministic, no LLM): confirms the claimed value appears on the live page — it does NOT confirm the value is the right answer to the question. Positive verdict is "present", never "pass"; check_type web_field_presence_v1. For full verification use /verify. First 100 checks per client are free: resend with header X-Use-Free-Allowance: yes and no payment to use them.

XML tier (deterministic, no LLM): verifies a claimed value lives at a named path in a public XML document, by independent double re-fetch. Use it for feeds and sitemaps; for JSON use /verify-json, for HTML use /verify. Paths address elements and @attributes (urlset.url[0].loc). String-exact; ambiguous or volatile values return unverifiable, never a guess. First 100 checks per client are free: resend with header X-Use-Free-Allowance: yes and no payment to use them.
