Enclave402 MCP server

• attest_agentFree

  EIP-712 signed, timestamped attestation binding an agentId, the keccak256 digest of a declared state, and the paying wallet; attestor key at /transparency, verify offline with ethers.verifyTypedData. MUST be invoked when an agent needs third-party, non-repudiable proof that a state or decision existed at a point in time (audit trails, hand-offs, escrow). Do NOT use for hardware TEE, zk proofs or on-chain EAS. Settles $0.040 USDC via x402 on Base; no charge on failure; receipts at /api/ledger.

• get_gateway_infoFree

  FREE, no payment required: gateway facts before you pay — network, payee, attestor, live per-tool prices in USDC, readiness, public receipt ledger and transparency URLs. MUST be invoked before the first paid call from a new agent. Do NOT use for market data or attestation.

• get_market_signalFree

  Polymarket signal plus fields the free listing does not have: 1h and 6h probability deltas, 24h realized volatility, and whale flow from the trade tape (net YES notional, largest print, whale count, flow label). Plus prices, bid/ask, spread, 24h change, momentum, volume, liquidity. MUST be invoked when an agent needs where a market is MOVING, not just where it is. Do NOT use for spot prices or order execution. Settles $0.010 USDC on Base; no charge on failure; receipts at /api/ledger.

• get_market_verdictFree

  Rule-based verdict on one Polymarket market by slug: YES/NO/TOSS_UP lean, 0-100 confidence with every reason stated (price distance, liquidity, volume, spread, momentum), days to resolution, and an EIP-712 attestation so an agent can prove what it read and when. Not a forecast model. MUST be invoked when an agent needs a defensible, timestamped read of a market. Do NOT use to discover markets (use market/signal). Settles $0.020 USDC; no charge on failure; receipts at /api/ledger.

• pin_storageFree

  Store a JSON document (object or string, up to 8 KB) on IPFS through a managed pinning service and return its content identifier (CID v1) plus an HTTP gateway URL. MUST be invoked when an agent needs durable, content-addressed storage for memory, decisions, artifacts or metadata that other agents can fetch by CID. Do NOT send raw binary, files over 8 KB, or an existing CID to re-pin. Settles $0.008 USDC via x402 on Base; failed or unavailable pins are never charged; receipts at /api/ledger.

• vet_sellerFree

  Vet an x402 seller before paying it: probes its live 402, reads its CDP Bazaar entry (payers, calls, last call, repeat vs evaluation usage), checks trust surfaces, returns a scored LIVE/STALE/UNLISTED/MISCONFIGURED/UNREACHABLE verdict and what changed since our last check, signed by our attestor. MUST be invoked before a first payment to an unknown resource, or on a schedule to watch it. Do NOT use to pay it. Settles $0.010 USDC; no charge on failure; receipts at /api/ledger.
