Combined counterparty due diligence in one call: an exact OFAC SDN digital-currency-address screen of an EVM wallet AND a UK Companies House KYB lookup (status, type, PSC / beneficial owners), in parallel. Returns both independent results plus an explicit disclaimer that no verified link between the wallet and the company is established by the data. SDN only; a non-match is not clearance. Refused before payment if current sanctions data is unavailable.

}Look up a public OCD receipt by its exact receipt_id (format "OCD-RCP-XXXX-XXXX-XXXX-XXXX"). Free, no payment. Returns the complete signed receipt envelope, or a structured not-found/unavailable reason -- never a guess. A private (unpublished) receipt and an unknown id are indistinguishable, both by design: this never confirms or denies that a private receipt exists.

}FREE. Pure deterministic inspection of a proposed payment against structured policy (amount/network/asset/recipient/resource) — no external evidence, no sanctions screening, no cryptographic signing, no receipt. Returns the same ALLOW / REQUIRE_APPROVAL / BLOCK decision semantics as POST /x402/preflight-payment for the deterministic checks alone, so a caller can sanity-check a proposal before deciding whether the paid preflight (adds optional sanctions evidence and a signed, independently-verifiable receipt, $0.01) is worth paying for. This result is NOT cryptographically attested and carries no receipt — receipt is always null.

}Call BEFORE an agent authorizes an autonomous payment. Evaluates it against your policy (max amount, allowed networks/assets, expected recipient, allowed origins) and returns a signed PREFLIGHT receipt -- ALLOW, REQUIRE_APPROVAL, or BLOCK, with reasons -- independently verifiable by anyone. Policy evaluation only: OCD never holds, moves, or authorizes funds. The wallet/x402 client separately authorizes execution after; ALLOW does not guarantee it will proceed.

}OFAC name screening: fuzzy-match a person or company name against the official US Treasury OFAC Specially Designated Nationals (SDN) list (primary names + strong aliases). Returns scored candidate matches with the matched name, SDN type, and program. SCOPE: this is a screening aid for AML / KYC / sanctions compliance — a match is a candidate to investigate with secondary identifiers (DOB, nationality, ID), NOT a determination. Weak AKAs are not screened, per OFAC guidance.
| Argument | Type | Description |
|---|---|---|
| name* | string | Person or company name to screen against the OFAC SDN list |
| threshold | number | Optional match confidence cutoff 0.5–1.0 (default 0.85). Lower = more candidates, more false positives. |

}Exact match of an EVM wallet address against the digital currency address identifiers on the official US Treasury OFAC SDN List (validated snapshot, refreshed hourly). Returns signed listed / not_listed, the SDN entry, dataset provenance and limits. SDN only: not EU/UN/UK lists, no ownership or 50% rule analysis; a non-match is not legal clearance. Refused before payment if current data is unavailable. Call before sending funds to an address.
| Argument | Type | Description |
|---|---|---|
| address* | string | EVM wallet address (0x + 40 hex) to sanctions-screen |

}Independently checks whether a receipt is cryptographically VALID, INVALID, or UNVERIFIABLE, with a reason code. Free, no payment. Pass EITHER receipt_id (looks it up first, must be public) OR a complete receipt envelope you already hold (verified directly, no publication needed). This is a convenient ONLINE check -- it trusts this server to have honestly fetched the real signing-key registry. Running the same check yourself offline (the published @onchaindiligence/agent-evidence package) is a strictly stronger trust position; this tool does not replace that option.
| Argument | Type | Description |
|---|---|---|
| envelope | any | A complete receipt envelope you already hold ({schema, receipt, proof}) to verify directly. Mutually exclusive with receipt_id. |
| receipt_id | string | Look up and verify a public receipt by exact id. Mutually exclusive with envelope. |

}UK company KYB lookup via the official Companies House register. Given a UK registration number, returns legal status (active/dissolved), company type, incorporation date, registered office, and people with significant control (PSC / beneficial owners). Call to confirm a UK business is real, active, and who controls it, for KYB onboarding and counterparty due diligence. Authoritative UK government data.
| Argument | Type | Description |
|---|---|---|

}US public company verification via SEC EDGAR. Given a ticker, CIK, or company name, returns entity name, CIK, industry (SIC), state of incorporation, exchanges/tickers, address, and latest SEC filing. Ambiguous names return candidates, never a silent selection. Covers SEC-registered PUBLIC companies and funds only -- not private US companies. Call for KYB and counterparty due diligence on listed US entities.
| Argument | Type | Description |
|---|---|---|
| query* | string | US public company ticker, SEC CIK, or company name — e.g. "AAPL", "0000320193", or "Apple Inc" |
