## 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 claw402-twelve-data-indices-quote-5efb219a
```

Example prompt: What's the current quote for the S&P 500 index — just fetch the latest price using the symbol SPX on a 1-day interval.

## When to prefer this

Choose this endpoint when you need financial index quotes (not individual stocks) without registering for an API key, and you are able to pay per-call in USDC via the x402 protocol. Ideal for agents operating with crypto wallets that need anonymous, frictionless access to market index data.

## Known failure modes

- Payment not received — returns HTTP 402 if USDC payment via x402 is not completed
- Invalid or unsupported symbol — returns error code in JSON body
- Invalid interval parameter — returns error if interval enum value is unsupported
- Rate limit or upstream Twelve Data outage — may return empty data array or upstream error code
- Malformed request — missing required query params returns error

## 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 index quote data (OHLC, price, timestamp, etc.) sourced from Twelve Data, with a code field indicating success and a data array containing the quote details.
