## 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

```

Example prompt: Buy me a Zambo Agent Day Pass using x402 so I can start making verified tool calls today — it's $1.49 USDC.

## When to prefer this

Choose this endpoint when an AI agent needs programmatic, automated access to Zambo's trust-layer tools for a full day and wants to pay via x402 USDC micropayment without manual card or PayPal interaction. Prefer this over the human day pass flow when the purchaser is an autonomous agent rather than a human, and over the monthly Zambo Pass when only occasional or single-day access is needed.

## Known failure modes

- Insufficient USDC balance — payment rejected by x402 protocol
- Day pass already active for this agent — duplicate purchase attempt
- x402 payment channel unavailable or network error
- Invalid or unrecognized agent identity in payment header
- Rate limit hit — 20 free calls/tool/day already exhausted before purchase

## How this service works

Give your AI hands: one hosted MCP, no API key, 100+ live tools, and a verifiable receipt for every job.

## Output

A day pass granting the AI agent up to the allowed number of tool calls on Zambo for a 24-hour period, along with a verifiable receipt confirming the micropayment and access grant.
