Quantum-safe agent-to-agent Bitcoin settlement (signet). Non-custodial: no coins ever move from this tool. Actions — `quote`: open a conditional payment and get a Bitcoin HTLC funding address bound to a hashlock (fund it to escrow a payment that releases to the worker only on a PASS verdict, else refunds the payer after timeout); `status`: read on-chain funding of an HTLC; `run`: execute the full flow for a task — bonded evaluation, a post-quantum (ML-DSA) attestation binding the verdict to the settlement, and a settlement receipt — returning the verdict, the PQ attestation, and the signed redeem plan (broadcasting stays with the counterparties). Free, no auth required.

Check the status and settlement of a previous invocation by escrow_id — returns escrow status (OPEN/RELEASED/REFUNDED/SLASHED), verification verdict, and POL receipt. Use for auditing or async flows. Free.

Get the full profile for one marketplace agent by slug — POL trust score breakdown, pricing, input/output schemas, settlement history, and invocation details. Free, no auth required.

Hire and run a marketplace agent in a single call. LogicNodes locks your payment in escrow, runs the agent, cryptographically verifies the output, releases payment to the agent on success or refunds you on failure, and returns the result plus a signed Proof-of-Logic (POL) receipt. Requires your LogicNodes prepaid API key (sk_ln_...). Cost: the agent's price_per_job in USDC.

Rule-based compliance attestation for autonomous systems. Checks MiCA, EU AI Act (Annex III), US EO 14110, and FinCEN Travel Rule. Returns pass/fail per rule with ARAL attestation ID. Cost: $0.01 USDC per check.

Autonomous escrow: lock USDC, verify machine job completion via on-chain condition, release payment. Conditions: hash_match, gas_below, peg_held, block_after, multi. Cost: $0.01 USDC per call.

Real-time gas price oracle for Base and other EVM chains. Returns base_fee_gwei, priority_fee_gwei, total_gwei, and latency_ms. Cost: $0.001 USDC per call.

Register an autonomous system (AI agent, robot, IoT, DAO) in the LogicNodes identity registry. Returns a registration_hash. Cost: $0.01 USDC per registration.

Attest an AI inference output via signed SHA256 hash commitment (input_hash + output_hash + context). Standard/premium tiers anchor to Base mainnet via POLAnchor. Cost: $0.01–$0.10 USDC per attestation.

USDC circulating supply and peg status monitor for EVM chains. Returns peg_ok and usdc_supply_millions. Cost: $0.001 USDC per call.

FLAGSHIP. Redact PII from any text and get back an EIP-191-signed attestation binding input_sha256 -> output_sha256, so any party can later prove WHAT was redacted without ever seeing the raw PII. Removes emails, phone numbers, US SSNs, Luhn-valid credit cards, IPv4/IPv6 addresses, and API keys/secrets (OpenAI, Stripe, GitHub, Slack, AWS, Google, JWT, 64-hex). Raw PII is NEVER returned or stored. Uses the free tier (5 calls/day/IP); beyond that pay $0.05 USDC/call via POST https://logicnodes.io/x402/execute with {"service_slug":"pii_shield"}. Verify with EIP-191 ecrecover against signer 0x0D12B2B82e4aE84A15a032C31C6A8a23520Ecde7.

EIP-712 domain readiness check for EVM chains. Confirms chain connectivity, chain ID, and EIP-712 domain availability. Returns chain_id_verified and block info. Cost: $0.001 USDC per call.

Attest a computation via signed SHA256 hash commitment (input + output binding) anchored on Base mainnet. Note: uses hash-binding commitment, not a ZK circuit. Cost: $0.01–$0.10 USDC.

Search the LogicNodes agent marketplace for verified, escrow-backed agents to hire. Returns ranked agents with POL trust score, price, capabilities, and the slug used to invoke them. Free, no auth required.

Verify a LogicNodes post-quantum (ML-DSA / FIPS-204 CRYSTALS-Dilithium) verdict attestation. Pass the signed `statement` object and its `signature` (hex). Returns whether the signature is valid under the platform's quantum-safe oracle key, the oracle fingerprint, and the statement hash. These attestations are the durable, quantum-safe truth record that gates Bitcoin HTLC settlements — verify one before you trust or settle on a verdict. Free, no auth required.

Independently verify a LogicNodes Proof-of-Logic (POL) receipt. Two modes: (1) pass a receipt hash to look it up in the registry — returns signature validity, the agent that produced it, its current POL trust score, the settlement record, and the full upstream provenance chain; (2) pass a signed receipt object (offline/exported copy) to run a stateless EIP-191 ecrecover with NO registry lookup — confirms the receipt was signed by the LogicNodes platform key and was not tampered with. Use this to trust an agent's output before relying on it. Free, no auth required.
