What it does

Moonpay X402 is an agent skill from moonpay/skills. Make paid API requests to x402-protected endpoints. Automatically handles payment with your local wallet.

Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with x402 and Solana. The repository describes itself as: Skills for AI agents to move money — on-ramps, swaps, wallets, deposits, and more via the MoonPay CLI. The licence is MIT.

Example prompts

“/moonpay-x402”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

User: "Upgrade my rate limit for a day."
Run: mp upgrade --duration day --wallet my-wallet --chain solana
The CLI handles the 402 payment flow automatically and applies the upgrade.

What it can do on your machine

Read from SKILL.md and the folder at commit aa672ab. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- agents.moonpay.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Moonpay X402 loads about 370 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 153 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~30
When it runs · the whole SKILL.md, loaded when a task matches: ~370

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: moonpay-x402
description: Make paid API requests to x402-protected endpoints. Automatically handles payment with your local wallet.
tags: payments, api

x402 paid API requests

Goal

Make HTTP requests to x402-protected endpoints. The CLI automatically detects 402 Payment Required responses, builds and signs a payment transaction with your local wallet, and retries the request with the payment proof.

Command

bash

mp x402 request \
  --method POST \
  --url <x402-endpoint-url> \
  --body '<json-body>' \
  --wallet <wallet-name-or-address> \
  --chain solana

Available x402 endpoints

Endpoint	Cost	Input
`https://agents.moonpay.com/x402/upgrade`	$1-$20	`{"duration": "day"}` or `{"duration": "month"}`

Example flow

User: "Upgrade my rate limit for a day."
Run: mp upgrade --duration day --wallet my-wallet --chain solana
The CLI handles the 402 payment flow automatically and applies the upgrade.

Notes

Requires a local wallet with USDC on Solana or Base.
Payments accepted on Solana mainnet and Base.
If the request fails (status >= 400), the payment is not settled — you don't pay for errors.
Use moonpay-auth to set up a local wallet first.

moonpay-auth — Create or import a local wallet.
moonpay-check-wallet — Check your wallet balance before making paid requests.
moonpay-upgrade — Upgrade your rate limit via x402.
