## 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 ddg-agent-payable-blockchain-address-lookup-2fcac2c3 -d '<json body>'
```

Example prompt: Look up the details for blockchain address 0x1234abcd...5678 using the DDG agent-payable chains endpoint — it costs $0.01 USDC per query.

## When to prefer this

Choose this endpoint when you need a pay-per-call, x402-compatible blockchain address lookup that integrates directly with agent payment flows using USDC. It is best suited for AI agents that can autonomously handle micropayments and need on-chain address data without maintaining a subscription or API key relationship.

## Known failure modes

- Payment not processed — returns 402 if USDC payment is missing or insufficient
- Invalid or malformed address input — likely returns a 4xx error
- Unsupported chain — may return an error if the chain type is not supported
- Network or provider downtime — 5xx server errors possible
- Schema validation failure if required fields (input, output) are missing from the request body
