How this service works
Leaderboard: pay a tiny fee to appear on a ranked scoreboard (?name=, ?url=, ?note=). No underlying data product — pure visibility. Ranked by cumulative amount paid; paying again bumps your rank.
Output
Returns a JSON object with a 'status' field (e.g. 'ok' or 'error') and a 'message' field describing the outcome of the listing submission.
Example use cases
Developer showcasing x402 experiment
“List my project 'OracleBot' on the leaderboard — the URL is https://oraclebot.xyz and the note should say 'automated on-chain price oracle demo'.”
Hackathon team self-promotion
“Add our team entry 'AuctionLabs' to the leaderboard with a link to https://auctionlabs.dev and a note that says 'live Dutch auction prototype on Base mainnet'.”
Solo builder logging a milestone
“Register my name 'cryptobuilder42' on the leaderboard — no URL, but add the note 'just shipped my first x402-gated API endpoint'.”
