Mint 1,000 PAY402 commemorative meme tokens on Base for $1 via x402 payment.
What it does
PAY402 is a commemorative meme token celebrating the x402 protocol era. The /api/mint endpoint accepts an x402 payment of $1 USDC on Base and mints 1,000 PAY402 (P402) tokens to the payer's address. The token has a max supply of 1 billion, no premine, and is described as a fair-launch souvenir with zero utility, zero roadmap, and no exchange listing guarantees.
The endpoint is live and responds with a standard x402 payment challenge (HTTP 402) when called without payment headers. It accepts POST requests and, upon successful payment, returns a JSON object containing a boolean success flag, a transaction hash, and the payer's address. The token contract is deployed on Base mainnet at 0xC09b6cd7009F117C19Ffb6CBA0af6f8186c44118.
This is explicitly a novelty/meme mint. The project's own site repeatedly states the token has no intrinsic value, no utility, no staking or airdrop mechanics, and may never trade on any exchange. Mint only if you're comfortable treating the cost as a non-refundable souvenir purchase.

Quality
The endpoint is live with a valid x402 challenge, output schema is provided, and the landing page gives clear context about what the mint does. However, there is no OpenAPI spec, no dedicated API docs, no input schema beyond the x402 payment header, and no usage examples beyond what can be inferred from the challenge and site copy.
