screen_wallet | Sanctions-screen an EVM wallet address against the Chainalysis on-chain oracle (OFAC SDN, EU, UN designations). Reflects current status, including delistings -- a once-designated address may now screen clean. Returns a sanctioned / not-sanctioned boolean (no case-level detail). Call before sending U |
screen_name | 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 / sa |
verify_uk_company | 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, |
verify_us_company | 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 |
diligence | Combined counterparty due diligence in one call: runs sanctions screening on a crypto wallet (Chainalysis oracle — OFAC SDN, EU, UN) AND a UK Companies House KYB lookup (status, type, PSC / beneficial owners) in parallel. Built for compliance agents vetting a counterparty that has both an on-chain w |
preflight_payment | 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 e |
inspect_payment | 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/prefl |
inspect_allowance | FREE. Deterministically inspect an ERC-20 allowance/revocation request against explicit network/token/spender/value policy. No wallet action, no signing, no chain read unless a separately requested preflight asks for it. |
preflight_allowance | Call BEFORE an agent asks its wallet to approve or revoke a Base USDC ERC-20 allowance. OCD evaluates strict policy and returns a signed portable allowance artifact. ALLOW is policy only, never wallet authority. |
observe_allowance | Given a signed OCD allowance preflight artifact and submitted Base transaction hash, independently inspect its canonical-USDC Approval event, Base safe-head finality, and historical allowance state. OCD never executes the transaction. |
inspect_swap | FREE. Deterministically inspect a narrow Base USDC-to-WETH direct Uniswap V3 swap against explicit policy. No wallet action or signing. |
preflight_swap | Call BEFORE an agent asks its wallet to execute a narrow Base USDC-to-WETH direct Uniswap V3 swap. OCD returns a signed portable policy artifact. ALLOW is policy only, never wallet authority. |
observe_swap | Given a signed OCD swap preflight artifact and Base transaction hash, independently inspect direct Uniswap V3 exactInputSingle calldata, ERC-20 transfers, and Base safe-head finality. OCD never executes the swap. |
inspect_bridge | FREE. Deterministically inspect a narrow Circle CCTP V2 Base-to-Ethereum native-USDC bridge request against explicit policy. No wallet action, no signing, no chain read. |
preflight_bridge | Call BEFORE an agent asks its wallet to bridge Base USDC to Ethereum via Circle CCTP V2 (depositForBurn). OCD evaluates strict policy and returns a signed portable bridge artifact. ALLOW is policy only, never wallet authority. |
observe_bridge | Given a signed OCD bridge preflight artifact, the Base depositForBurn transaction hash, and (once available) the Ethereum receiveMessage transaction hash, independently observe both chains, verify the CCTP message identity matches, and reconcile against the authorized action. Source-only observation |
inspect_staking | FREE. Deterministically inspect a narrow Ethereum Lido stETH submit request against explicit policy. No wallet action, signing, or chain read. |
preflight_staking | Call BEFORE an agent asks its wallet to submit ETH to Lido stETH. OCD evaluates strict policy and returns a signed portable staking artifact. ALLOW is policy only, never wallet authority. |
observe_staking | Given a signed OCD staking preflight artifact and Ethereum transaction hash, independently inspect the canonical Lido Submitted event, transaction sender/value, optional minted shares, and Ethereum finalized-head finality. OCD never stakes ETH. |
get_receipt | 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 |
verify_receipt | 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 convenie |
