## 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 starchild-relay-taapi-rsi-indicator-9a29ca2a -d '<json body>'
```

Example prompt: Can you pull the RSI for BTC/USDT on Binance using a 1-hour interval so I can see if Bitcoin is currently overbought or oversold?

## When to prefer this

Use this endpoint when you need RSI values for crypto trading pairs via TAAPI.io but want to pay per-call with USDC micro-payments via x402 rather than managing a direct TAAPI subscription; ideal for agents making infrequent or on-demand technical analysis requests without a long-term API contract.

## Known failure modes

- Invalid or missing TAAPI secret returns authentication error
- Unsupported exchange name returns 400 or upstream error
- Invalid trading pair symbol returns error from TAAPI
- Unauthenticated request without X-PAYMENT header returns 402 payment required
- Invalid interval string returns upstream validation error
- Upstream TAAPI service unavailable causes 502 or timeout

## How this service works

All-in-one reputable data source for AI agents and developers. Crypto spot/OHLC, derivatives funding rates, open interest, liquidations, forex, commodities, indices, social sentiment, DeFi protocols, and more — 17+ upstream data sources behind a single x402 paywall.

Usage: Send requests to any proxied path (e.g. GET /coingecko/api/v3/...). Unauthenticated requests receive a 402 challenge with payment instructions. Include X-PAYMENT header with a valid signature to access data.

## Output

Returns the current RSI value (0–100) for the specified trading pair on the given exchange and timeframe, indicating momentum and potential overbought (>70) or oversold (<30) conditions.
