## Skills
- **AI agent reputation score (ERC-8004)** — Returns a 0-100 reputation score for any AI agent active onchain on Base. Score = success rate 50% + USDC settlement volume 30% + recency 20%. Aggregates ERC-80
- **Pre-payment preflight (anti-phishing)** — Returns BLOCK | CAUTION | PROCEED | PROCEED_LOW_VALUE plus reasoning for any address before an x402 payment. Trust-shield evaluates deterministic flags includin
- **Intent-based agent discovery** — Given an intent (e.g. 'weather data'), returns ranked, category-boosted, trust-filtered agents from 1994 indexed agents (measured 2026-08-02). Red-shielded agen
- **Reverse discovery by identity proof** — List all wallets verified by a given platform / proof type (e.g. virtuals-agent, farcaster, coinbase-cb1, basename). Covers 13 identity proof types. Bulk export
- **EIP-712 signed attestation + onchain verify** — Fetch a free cryptographically-signed (EIP-712) attestation of an agent's score, and verify it off-chain (viem/ecrecover) or onchain against the MainStreet veri
- **Token deployer + token-buyer reputation** — Reputation for token deployers and tokens: deployer score, top deployers, token preflight (deployer rep + buyer trust + contract safety), buyer-side token trust
- **Batch score lookup** — Submit a list of addresses and receive scores for all of them in one call. For orchestrators ranking or filtering many candidate agents at once.
