claw-x402 — AI Agent Native API Provider

claw-x402 is an API provider built for the agentic era. No API keys, no signups, no monthly subscriptions. Just pay with USDC per request via the x402 protocol and instantly access Twitter, Instagram, and more.

Traditional API providers: Sign up → Generate API key → Subscribe to a plan → Manage rate limits → Rotate keys

claw-x402: Have a wallet → Call the endpoint → Pay per request. Done.

AI Agents can autonomously discover available endpoints, pay the exact cost per call, and get results — all without human intervention or pre-provisioned credentials.

Prerequisites & Setup

1. awal CLI Authentication

The awal CLI (

npx awal@latest

) handles wallet operations and x402 payments. You must authenticate before making paid API calls.

Check status:

bash

npx awal@latest status

If not authenticated, use the email OTP flow:

bash

# Step 1: Send OTP to your email
npx awal@latest auth login user@example.com
# Output: flowId: abc123...

# Step 2: Verify with the 6-digit code from email
npx awal@latest auth verify abc123 123456

# Confirm authentication
npx awal@latest status

See the

authenticate-wallet

skill for details.

2. Fund the Wallet

Check your USDC balance:

bash

npx awal@latest balance

If insufficient, fund via Coinbase Onramp:

bash

npx awal@latest show

This opens the wallet companion UI where you can fund with Apple Pay, debit card, bank transfer, or Coinbase account. Alternatively, send USDC on Base directly to your wallet address:

bash

npx awal@latest address

See the

fund

skill for details.

Troubleshooting

Error	Cause	Fix
HTTP 402	Payment required	Use `npx awal@latest x402 pay` instead of plain `curl` to make the request
HTTP 502	Upstream API error	The backend service may be temporarily unavailable. Retry after a few seconds
`"not signed in"`	Wallet not authenticated	Run `npx awal@latest auth login <email>` to authenticate. See `authenticate-wallet` skill
`"insufficient balance"`	Not enough USDC	Run `npx awal@latest show` to fund the wallet. See `fund` skill
Empty response	Invalid parameters	Check query parameters — e.g. `/user` requires `?username=` , `/user-tweets` requires `?user=` (numeric ID)
Instagram 400	Missing request body	Instagram endpoints require POST with JSON body: `-X POST -d '{"username": "..."}'`
