# 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](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
```bash
npx agentcash wallet info
```
Returns wallet address, USDC balance, and deposit link. Always check before expensive operations.
### Redeem Invite Code
```bash
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/<wallet-address>`
**Important**: Only Base network USDC. Other networks or tokens will be lost.
## Calling Paid APIs
### 1. Discover endpoints
```bash
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)
```bash
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
```bash
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.
