agentcash Wallet & Paid APIs
Call any x402-protected API with automatic payment. Payment is the authentication — no API keys or subscriptions needed.
Setup
If the agentcash CLI is not yet installed, see rules/getting-started.md for installation and wallet setup.
Wallet Management
Your wallet is auto-created on first use and stored at ~/.agentcash/wallet.json.
Check Balance
npx agentcash wallet info
Returns wallet address, USDC balance, and deposit link. Always check before expensive operations.
Redeem Invite Code
npx agentcash wallet redeem YOUR_CODE
One-time use per code. Credits added instantly. Run npx agentcash wallet info after to verify.
Deposit USDC
1. Get your wallet address via npx agentcash wallet info
2. Send USDC on Base network (eip155:8453) to that address
3. Or use the deposit UI: https://x402scan.com/mcp/deposit/
Important: Only Base network USDC. Other networks or tokens will be lost.
Calling Paid APIs
1. Discover endpoints
npx agentcash discover https://stableenrich.dev
Returns all endpoints, pricing, and usage instructions. Read the instructions field — it has critical endpoint-specific guidance.
2. Check schema (optional)
npx agentcash check https://stableenrich.dev/api/apollo/people-search
Returns full request/response JSON schemas and pricing for a specific endpoint.
3. Make a paid request
npx agentcash fetch https://stableenrich.dev/api/apollo/people-search -m POST -b '{"person_titles": ["CEO"], "person_locations": ["San Francisco"]}'
Payment is automatic: sends request, gets 402 challenge, signs USDC payment, retries with credential, returns result. Payments settle only on success (2xx) — failed requests cost nothing.
