If the wallet is not authenticated, refer to the authenticate-wallet skill.
npx awal@2.10.0 x402 pay <url> [-X <method>] [-d <json>] [-q <params>] [-h <json>] [--max-amount <n>] [--json]
| Option | Description |
|---|---|
-X, --method <method> | HTTP method (default: GET) |
-d, --data <json> | Request body as JSON string |
-q, --query <params> | Query parameters as JSON string |
-h, --headers <json> | Custom HTTP headers as JSON string |
--max-amount <amount> | Max payment in USDC atomic units (1000000 = $1.00) |
--correlation-id <id> | Group related operations |
--json | Output as JSON |
X402 uses USDC atomic units (6 decimals):
| Atomic Units | USD |
|---|---|
| 1000000 | $1.00 |
| 100000 | $0.10 |
| 50000 | $0.05 |
| 10000 | $0.01 |
IMPORTANT: Always single-quote amounts that use $ to prevent bash variable expansion (e.g. '$1.00' not $1.00).
Before constructing the command, validate all user-provided values to prevent shell injection:
https:// or http://. Reject if it contains spaces, semicolons, pipes, backticks, or shell metacharacters.^\d+$).Do not pass unvalidated user input into the command.

Use when you or the user want to generate, create, make, or forge a 3D model, asset, object, mesh, or prop from a text description — "make a 3D model of a robot", "generate a GLB of a sword", "I need a 3D chair". Runs on the FREE text→3D lane (no key, no account, free). Returns a GLB URL plus a browser viewer link.
Sign in to the wallet. Use when you or the user want to log in, sign in, connect, or set up the wallet, or when any wallet operation fails with authentication or "not signed in" errors. This skill is a prerequisite before sending, trading, or funding.
Add money to the wallet. Use when you or the user want to fund, deposit, top up, load, buy USDC, add funds, onramp, or get USDC. Also use when the wallet has insufficient balance for a send or trade operation, or when someone asks "how do I get USDC?"
Build and deploy a paid API that other agents can pay to use via x402. Use when you or the user want to monetize an API, make money, earn money, offer a service, sell a service to other agents, charge for endpoints, create a paid endpoint, or set up a paid service. Covers "make money by offering an endpoint", "sell a service", "monetize your data", "create a paid API".
Query onchain data on Base using the CDP SQL API via x402. Use when you or your user want to view onchain information about decoded blocks, transactions, and events.
Auto-rig a static 3D GLB model into an animation-ready one. Use when you or the user have an existing GLB and want to rig it, add a skeleton, add bones, make it posable, or make it animatable — "rig this model", "add a skeleton to my GLB", "make this character animation-ready". Takes a GLB URL, adds a humanoid skeleton plus skin weights, and returns the rigged GLB URL and a pose-studio link.
