evm-tx-toolkit.mtree.workers.dev
Risk-score an ERC-20 token on Base, Ethereum, Arbitrum, Optimism, or Polygon using on-chain contract reads, proxy/owner checks, GoPlus Token Security signals, tax/honeypot flags, and a composite 0-100 verdict. Returns JSON. Price 0.50 USDC on Base via x402. Demo/preview: https://evm-tx-toolkit.mtree.workers.dev/demo/token/risk_scan. Contact: https://evm-tx-toolkit.mtree.workers.dev/contact.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.
Asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.
Accepts

Hand this page to an agent
Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
No per-endpoint history for this service yet, so this is payments indexed to its PROVIDER's wallet over 30 days. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service evm-tx-toolkit.mtree.workers.dev and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=evm-tx-toolkit.mtree.workers.dev' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://evm-tx-toolkit.mtree.workers.dev/v1/token/risk_scan, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
