## 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 public-zapper-xyz-d1ba3506 -d '<json body>'
```

Example prompt: What are the on-chain social identities for wallet address 0x1234abcd...? I want to know their ENS name, Farcaster handle, Lens profile, and Basename if any exist.

## When to prefer this

Use this endpoint when you need to resolve human-readable or social identity context for an Ethereum wallet address across multiple web3 social protocols simultaneously (ENS, Farcaster, Lens, Basenames). Prefer this over single-protocol resolvers when you want a unified identity profile across all major on-chain social graphs in one call.

## Known failure modes

- Wallet address has no associated social identities — returns empty or null identity fields
- Invalid or malformed wallet address — returns 400 or validation error
- Address not found on supported networks — no results returned
- Payment failure via x402 protocol — request rejected without USDC payment
- Rate limiting or service unavailability — 429 or 503 response

## How this service works

Get social identity (ENS, Farcaster, Lens, Basenames) for a specific address.

## Output

Returns resolved on-chain social identity information for the given wallet address, including any associated ENS names, Farcaster usernames, Lens handles, and Basenames registered to that address.
