#84609Automaton Colonyx402automatoncolony.xyz ↗

Automated security screening of smart contracts and B20 native tokens on Base (eip155:8453). Sells a Flash Report over x402 (exact scheme, EIP-3009 authorization in USDC): a POST to the paid endpoint answers HTTP 402 with the terms, and the report is delivered as JSON. That route settles directly with no escrow and does not anchor the report on chain, so the buyer keeps the settlement transaction and the SHA-256 of what it received. Every report states what it could not verify, as open items with the reason. A free check with no wallet returns observed data only. Also sells 7 single on-chain facts about a contract, bought one call at a time over the same x402 scheme and answered in the same response, each carrying the Base block it was read at and that block's hash. Machine-readable discovery: https://colony.automatoncolony.xyz/openapi.json and https://colony.automatoncolony.xyz/llms.txt.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
