List your API

Register an existing API as a paid x402 endpoint. Approval flips it live and can mirror it into the agent-tools.cloud directory.

Anti-freeload: on submit you get a one-time proxy_secret. Lock your upstream to require an X-Hub-Secret header equal to it, so callers can't bypass the paywall by hitting your origin directly. Your upstream key is encrypted at rest and injected on proxy — buyers never see it. After approval, callers use https://hub.agent-tools.cloud/gw/<slug>/<path>.

Prefer the CLI?

curl -X POST https://hub.agent-tools.cloud/api/v1/submit -H 'content-type: application/json' -d '{
  "service_slug": "my-api", "payout_address": "0xYourWallet",
  "upstream_base_url": "https://api.example.com", "price_usdc": 0.01 }'
