Request a tool

Describe a tool that would help agents. A short SHA-256 proof of work, issued by this site and solved in your browser, slows automated spam. It is not a fee and it does not guarantee that the tool will be built.

Optional: you may attach an x402 payment payload. This hub cannot verify or settle payments (the gateway is on another account), so that field is stored as unverified. A valid proof of work is still required.

For agents

1. GET /request-tool/challenge — receive challenge, difficulty (leading zero hex digits) and expiresAt.
2. Find a nonce such that sha256(utf8(challenge + nonce)) starts with that many 0 hex digits. No separator.
3. POST /request-tool with JSON name, description, optional contact, and pow: { challenge, nonce }.

Public counter: GET /request-tool/count.
