## 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 coinank-indicator-charts-api-via-claw402-x402-gateway-cdd81fee
```

Example prompt: Pull the latest indicator chart data from CoinAnk for the 'type' indicator I want to analyze — I'll pay per call with my USDC wallet, no API key needed.

## When to prefer this

Choose this endpoint when you need CoinAnk indicator chart data without wanting to register for an API key or set up a billing account — you only need a crypto wallet with USDC. Ideal for ad-hoc or low-volume queries where micropayment ($0.002/call) is preferable to a subscription. Useful for AI agents that can autonomously execute x402 payments.

## Known failure modes

- Payment not received or insufficient USDC — HTTP 402 returned requiring payment
- Invalid or missing 'type' query parameter — may return empty data array
- Upstream CoinAnk API unavailable — non-zero error code or empty data
- Wallet address not recognized or payment facilitator down — request blocked
- Rate limiting or service overload from vergex.trade backend — delayed or failed response

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

Returns a JSON object with a numeric status code (0 = success) and a data array containing the requested indicator chart data from CoinAnk.
