Wallet Safety Checks
Is it safe to pay this address? One check before sending or accepting crypto: OFAC SDN sanctions screen, wallet age, EOA or contract, first funder and recent large transfers on Base, Ethereum, Arbitrum, Optimism or Polygon (wallet kind and activity on Solana), plus the token's 0-100 risk score when a token is given. Returns ok, caution or block with plain reasons and each check in full. Rules-based, not legal advice.

Provider
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
The payment requirements as published to the catalog. Read the live 402 before paying — a price here is a claim, not a quote.

Using Roundhouse, look up the x402 service Wallet Safety Checks 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=Wallet%20Safety%20Checks' 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://ca-tax-api-mainnet.lxtap.workers.dev/check, 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. 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.
