Lumen Works Agent API (Lumen Pre-Sign Check + Lumen Agent Utilities)

13 pay-per-call tools for AI agents, led by a "should I sign this?" pre-sign check, paid per request in USA₮ or USDC on Celo through Celo's x402 facilitator (or USDC on Base). No signup.

Lumen Works Agent API is one x402 origin with two services. Lumen Pre-Sign Check (POST /v1/tx/explain, $0.002) is what an agent calls before signing any EVM transaction or EIP-712 message: it returns a summary, risk flags and a verdict (looks_ok / review / do_not_sign_unless_intended), flagging unlimited approvals, Permit/Permit2, setApprovalForAll, admin calls, zero-price Seaport orders, chain mismatch and x402 payTo mismatch. Lumen Agent Utilities adds 12 more tools: x402 header lint, EIP-712 decode, calldata decode, EVM address/ENS, domain DNS+RDAP ($0.002 each), and web page to Markdown, URL unfurl, PubMed, arXiv, SEC EDGAR filings, weather forecast and Polymarket markets ($0.001 each). Every paid route accepts USA₮ and USDC on Celo, settled gaslessly through x402.celo.org, plus USDC on Base. There is a free tier of 20 calls/hour, agents are not charged when a call errors, and both services are remote MCP servers in the official MCP registry (io.github.Dansgit2b/lumenworks-decoder, io.github.Dansgit2b/lumen-presign-check). Informational, not a security guarantee; early-stage and unaudited.
