## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentcash-send-universal-api-access-via-x402-payment-2414d0e1 -d '<json body>'
```

Example prompt: Use my AgentCash balance to send a paid API request to fetch the latest crypto price data — deduct $1 USDC from my account via x402 and return whatever the target API responds with.

## When to prefer this

Prefer this endpoint when an AI agent needs to access a variety of external APIs without managing separate credentials or billing accounts for each — especially when the agent must autonomously pay for capabilities at runtime using USDC via x402. Ideal for agentic workflows where programmatic micropayment-gated API access is required.

## Known failure modes

- Insufficient USDC balance — payment rejected before API call is made
- Target API unavailable or returns an error after payment is processed
- Invalid x402 payment header format — authentication failure
- Unsupported target API — not accessible through AgentCash routing
- Network timeout on outbound API call after payment deducted

## How this service works

One balance, access to every API on the internet. AgentCash lets AI agents buy data, tools, and capabilities using x402.

## Output

The agent receives the response payload from the target API after the x402 micropayment is processed, along with confirmation that $1 USDC was deducted from the AgentCash balance.

## Example request

```json
{
 "amount": 0.5,
 "address": "0x1234567890abcdef1234567890abcdef12345678",
 "network": "base"
}
```
