Agents pay.
Your coin gets bought.

Every coin on 402PAD gets a skill AI agents pay to use with x402. Every payment buys the coin back. On Solana.

01How it worksshare ↗ How it works on X

From call to buyback.

Four steps. One loop. Every call prints a receipt.

  1. 01. LAUNCH

    Create a coin on 402PAD. It drops into the slot and goes live on Solana.

    MINT · $EXAMPLE
    name · ticker · image → minted on Solana

  2. 02. SKILL

    Give it a skill agents can use. It becomes a paid API endpoint and an MCP tool agents can discover.

    price
    0.01 USDC
    default: the coin's own AI personality

  3. 03. PAY

    Agents pay per call with x402 in USDC. No account, no API key: the wallet is the key.

    HTTP · x402
    1. → GET /api/example/ask?q=gm
    2. ← 402 Payment Required
    3. PAYMENT-REQUIRED: 0.01 USDC · solana
    4. … agent wallet signs 0.01 USDC
    5. → GET /api/example/ask?q=gm
    6. PAYMENT-SIGNATURE: eyJ4NDAyVmVy…
    7. ← 200 OK
    8. {"answer":"gm. bought back."}

  4. 04. BUY BACK

    Every payment is swapped into the coin automatically: half held or burned, half to the creator.

For the agents' humans.

If your agent can make an HTTP request and sign with a wallet, it can use any coin on 402PAD.

  1. An endpoint per coin

    Every coin's skill lives at 402pad.fun/api/<ticker>. Plain HTTP, JSON in, JSON out.

  2. x402 payments

    The endpoint answers 402 with its price. The agent signs a USDC payment on Solana and retries. 200 OK. No accounts, no API keys.

  3. An MCP tool

    Each skill is also published as an MCP tool, so agents can discover it, read its price and call it like any other tool.

  4. A receipt per call

    Every payment settles on-chain and is swapped into the coin. Every call prints a receipt.

Examples follow the public, open x402 flow. Endpoints and coin are fictional until launch. Full docs are in the print queue.

// Example: an agent calls a coin's skill and pays per call with x402.// npm i @x402/fetch @x402/svm @solana/kitimport { wrapFetchWithPayment, x402Client } from "@x402/fetch";import { ExactSvmScheme } from "@x402/svm/exact/client";import { createKeyPairSignerFromBytes } from "@solana/kit";// No account, no API key: the wallet is the key.const signer = await createKeyPairSignerFromBytes(agentSecretKey);const client = new x402Client();client.register("solana:*", new ExactSvmScheme(signer));const fetchWithPayment = wrapFetchWithPayment(fetch, client);// First try gets 402 Payment Required. The client pays 0.01 USDC,// retries with the signed payment, and gets 200 OK.const res = await fetchWithPayment("https://402pad.fun/api/example/meme", {  method: "POST",  headers: { "content-type": "application/json" },  body: JSON.stringify({ input: "make a meme about Mondays" }),});console.log(await res.json()); // the skill's resultconsole.log(res.headers.get("PAYMENT-RESPONSE")); // settlement receipt

09FAQshare ↗ FAQ on X

Small print.

Read it. It's short.

What is x402?
An open standard that lets software pay for an API call inside the request itself, usually in USDC. No accounts or API keys.
Who pays?
AI agents that use your coin's skill, like any paid API.
Where does the money go?
It's swapped into the coin automatically: half held or burned, half to the creator. Every payment is on-chain.
Do agents really pay for things like this?
Agents already pay for APIs with x402 today. Whether they use a specific coin's skill depends on how useful it is.
Is it live?
Agent payments go live in stages. Every update is posted on @402pad.
What's the contract address?
Only posted on this site and @402pad. Anything else is fake.CA: coming soon
Is this financial advice?
No.
