Mizan report card for any of 4,325 x402 operators (64,168 endpoints on file) — this call: api.loyalspark.online. Liveness across surveys, latency, x402 conformance, price demanded at the door vs price advertised in the catalogue, and for endpoints Mizan actually paid for, whether they delivered, refused, or charged and delivered nothing — with the on-chain tx. Replace the last path segment with any host from GET /api/pagella.

Lint any x402 endpoint before you pay it: fetches the unpaid 402 challenge (v1 body or v2 PAYMENT-REQUIRED header), decodes price/network/asset/payTo, flags non-USDC assets, testnets, missing bazaar metadata and malformed fields.

Base mainnet wallet snapshot for counterparty vetting: ETH + USDC balance, tx count (nonce), EOA vs contract, and whether it holds an ERC-8004 agent identity NFT.

Debug an x402 payment before you submit it — why does USDC answer invalid signature? Verifies the EIP-3009 transferWithAuthorization (EIP-712 signer, v, low s, validity window) and the seller's terms…

Wallet risk score 0-100 with component breakdown for an EVM address.

🆕 Built for liquidator / MEV searchers. Reconstructs the active borrower set on a Morpho Blue market from Borrow events, prices every position onchain in one multicall, and ranks them by liquidation health — flagging positions liquidatable NOW (health <= 1.0) and those one small move away, with the collateral price drop that tips each over. market= optional (defaults cbBTC/USDC), maxHealth= cutoff (default 1.1). Not financial advice.

🆕 First lending tooling in the catalog. Reads a Morpho Blue position on Base (the largest lending venue on Base) and returns its liquidation health in one call: health factor, current vs liquidation LTV, and the exact collateral price drop that triggers liquidation. Built for borrowing agents and treasuries that need to know how close they are before the market cuts them — Morpho's own API is deferred. Pass wallet= and optionally market= (defaults to cbBTC/USDC). Not financial advice.

🆕 A MetaMorpho vault spreads your deposit across Morpho Blue markets — your real risk is WHERE the curator put it and WHO can move it. Reads the vault's live allocation (concentration, per-market collateral + liquidation LTV), idle share, performance fee, timelock, and control (curator/owner/guardian, and whether one address holds both). Returns a diversified / concentrated / control_risk verdict: the read before parking funds in a yield vault. vault= required. Not financial advice.
