https://api.automatonsvrn.xyz/.well-known/x402 Our Verdict
Our AI team checked this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."
Pre-flight safety checks for Base before an agent signs: EVM bytecode analysis with honeypot and mint-backdoor detection (`GET /v2/security/scan?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`, $0.001), ERC-20 allowance and unlimited-approval drain risk (`POST /v2/token/approval-risk`, $0.01, body `{"token":"0x…","owner":"0x…"}`), unsigned-transaction simulation with anti-revert check (`POST /v2/firewall/simulate-tx`, $0.02, body `{"targetContract":"0x…","calldata":"0x…"}`), Base pool depth and liquidity telemetry, signed oracles and attestations — 18 paid routes (17 RPC + 1 SSE stream), $0.001–$0.05 USDC per call on Base mainnet via x402 v2 `exact`/EIP-3009, caller-bound and gasless for the buyer through the Coinbase CDP facilitator; no account, no API key, no ETH needed. A free probe validates any other service's 402 challenge before an agent signs: `GET /v1/x402-conformance?url=` (9 named checks, no payment). MCP server with 20 tools at `/mcp` and official Agent Kit SDK.
