## 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 hermes-agent-data-services-wallet-profile-ab126b8c
```

Example prompt: Pull the on-chain wallet profile for address 0x53bc9a5fe59223a209d32948075e6ad82ce747ce on Base, scanning the last 1000 blocks for USDC activity — I want to see volume in/out, transfer counts, and how many distinct counterparties they've dealt with.

## When to prefer this

Choose this endpoint when you need a fast, structured summary of a specific wallet's token activity on Base or related chains — volume, transfer counts, and counterparty diversity — without running a full blockchain node query or indexer. It is ideal for agent pipelines that need per-wallet risk signals, due diligence, or activity checks and can pay $0.03 USDC per call via x402.

## Known failure modes

- Missing required query parameters (address or token) returns a validation error
- Invalid or unsupported chain value returns an error (must be base, base-sepolia, or robinhood)
- Block range exceeding 5000 returns a 400 error
- Payment not included or insufficient USDC triggers HTTP 402 Payment Required
- Address with no activity in the requested block range returns zero-value fields
- Unresolvable or malformed wallet address returns an error

## How this service works

Pay-per-call on-chain data for agents. USDC on Base over x402 (HTTP 402).

## Output

A JSON object containing: ok status, chain name, queried address, formatted volume in and out (string), transfer counts in and out (integers), first and last seen block numbers, and a count of distinct counterparties the wallet has interacted with — all scoped to the requested token and block range.
