One call, one answer: is this wallet, agent, or token contract safe to pay? MainStreet returns a 0–100 reputation score and a SAFE / CAUTION / BLOCK verdict, signed on Base, verifiable onchain — callable by any agent before it routes USDC to a counterparty it doesn't yet trust.
SAFE · CAUTION · BLOCK — in under 100 ms.
Paste a wallet, agent, or token contract. Free snapshot read. Live re-score forces a fresh ERC-8004 read + signed attestation ($0.05 USDC via x402 paywall).
Need the compact agent-shaped verdict? Call POST /api/agent/check with {subject, type, depth} — returns {verdict, score, attestation} in <100 ms.
Each agent is identified by its onchain address. We fold ERC-8004 ReputationRegistry feedback, x402 facilitator settlements, Virtuals ACP completions, and multi-source identity proofs into a single EIP-712 signed score.
Your agent is about to route USDC to a wallet, agent or token. Check it first: preflight("0x…").
Back comes SAFE / CAUTION / BLOCK + a 0–100 score from ERC-8004 feedback, x402 settlements & rug-risk — EIP-712 signed, verifiable onchain.
Pay via x402 only if SAFE. Sign a peer receipt after the call — the counterparty's score updates next snapshot.
Live snapshot from /leaderboard. Refreshed every 24h.
No SDK install, no auth. Ten tools natively in Claude, Cursor, Windsurf — or one HTTP call.
