## 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 quantaflow-x402-gateway-rapid-indian-stock-exchange-api-d79f3745 -d '<json body>'
```

Example prompt: Can you look up the current stock price and today's trading volume for Reliance Industries on the Indian stock exchange?

## When to prefer this

Use this endpoint when you need Indian stock market data (NSE/BSE listings, Nifty/Sensex, individual equities) and want to pay per-call via x402 USDC micropayments rather than maintaining a subscription. Useful for agents that need infrequent or on-demand Indian financial data without a monthly API subscription commitment.

## Known failure modes

- Payment failure — insufficient USDC balance or x402 payment rejected, returns 402 status
- Upstream API unavailability — the proxied Indian stock exchange API may be down or rate-limited
- Invalid path — specifying a non-existent API route returns an upstream 404
- Invalid query parameters — malformed or unsupported query fields may return an upstream error
- Stale or delayed data — stock data may not be real-time depending on upstream provider tier

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The raw upstream response from the Indian Stock Exchange API, including stock quotes, price data, company financials, or index values, passed through as-is with the original content type after successful $0.01 USDC micropayment.
