## 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 apex-faucet-arc-counterparty-profiler-040f337d
```

Example prompt: Can you pull up the token profile for Arc address 0x4e8a2b3f1c9d0a7e6f5b2c1d3a4e5f6b7c8d9e0f — I want to see the symbol, current USD price, and how many holders it has?

## When to prefer this

Use this endpoint when you need lightweight token profile data (symbol, price, holder count) for a specific Arc blockchain address without needing a full analytics platform. It is ideal for quick pre-trade checks, counterparty screening, or enriching Arc address metadata in an automated workflow. It costs only $0.004 USDC per call, making it cost-effective for frequent lookups.

## Known failure modes

- Invalid or malformed 0x address returns an error or ok:false
- Address not found on Arc network returns empty or null data
- Payment failure due to insufficient USDC balance
- Rate limiting if called too frequently
- Network timeout on Arc chain data retrieval

## How this service works

Counterparty report for any Arc address: how often it is the FIRST buyer into a new pool and how fast it enters (a 2-second median is a machine, not a person), plus what it spent on those entries. IMPORTANT LIMIT: our scanner records only a pool's first buyer and only that pool's first 8 swaps, so later sales are NOT observed — treat the money figures as entry spend and early exits, not a full ledger. Behaviour, not identity; absent from our index means unknown, not safe.

## Output

A JSON object containing ok (success boolean), data (with token symbol, holder count, and USD price), paid (amount charged), tier (pricing tier label), and asset (payment currency used, e.g. USDC).
