## 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 agent-rest-stop-addresspack-34ebb6e4 -d '<json body>'
```

Example prompt: Package the Ethereum address 0xAbC...123 on chain ID 1 with the memo 'payment leg 2' into a single forwarding object the next agent can send as-is.

## When to prefer this

Use this endpoint when an agent pipeline needs to pass a blockchain address and chain identifier to a downstream agent in a single, self-contained object without the receiver needing to reformat or reassemble fields. Ideal for multi-hop agentic workflows where each hop consumes a pre-packaged payload.

## Known failure modes

- Missing required address or chain_id field returns a validation error
- Malformed address string (wrong format or checksum) may be rejected
- Invalid or unsupported chain_id value may cause downstream routing failures
- Empty payload body returns a 400-level error
- Payment not included or insufficient USDC causes a 402 Payment Required response

## How this service works

One object the next hop can send as-is.

## Output

A single JSON object containing the address, chain_id, and memo fields formatted and ready for the next agent hop to forward without modification — no further assembly required.
