## 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 blockrun-price-indicator-api-0b14a598
```

Example prompt: What's the current RSI for BTC right now? Also pull the MACD while you're at it so I can see if it's showing bullish momentum.

## When to prefer this

Choose this endpoint when you need computed technical analysis indicators (RSI, MACD, Bollinger Bands, EMA) for a specific crypto symbol on a pay-per-call basis with no API key required. Prefer this over general market data feeds when you specifically need momentum, trend, or volatility indicators rather than raw price or order book data.

## Known failure modes

- Missing required 'symbol' param returns 400 or error response
- Missing required 'indicator' param returns 400 or error response
- Unsupported indicator name returns error or empty result
- Invalid or unlisted trading symbol returns no data
- Payment not settled (x402) causes 402 Payment Required response
- Rate limit or insufficient USDC balance causes request failure

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output

Returns computed technical indicator values (e.g. RSI score, MACD line/signal/histogram, Bollinger Band upper/middle/lower levels, or EMA value) for the requested crypto symbol and indicator type
