## 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 x402-toolbox-chain-token-transfers-6eaa1fc4
```

Example prompt: Can you pull the recent token transfer events on the Base chain for me? I'll pay per call — no API key needed.

## When to prefer this

Choose this endpoint when you need to retrieve on-chain token transfer data without going through a traditional API key signup — ideal for autonomous AI agents that authenticate via micropayment (x402/USDC on Base). Best suited for lightweight, pay-per-call queries against blockchain transfer events where cost-per-call ($0.002 USDC) is acceptable and no persistent account is needed.

## Known failure modes

- Invalid or unsupported schema value returns an error response
- Payment not fulfilled (x402 protocol failure) results in 402 Payment Required
- Network timeout from Cloudflare Worker if the chain RPC is slow
- Empty result set if no transfers match the provided schema
- Malformed query parameter causes a 400-level error

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with an 'ok' and 'paid' status flag along with token transfer records retrieved from the specified blockchain schema, including transaction details such as sender, receiver, token amount, and block information.
