## 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-rsi-indicator-api-polygon-70948e89
```

Example prompt: What's the 14-period RSI for AAPL on a daily timespan, closing price series, most recent 10 values in descending order?

## When to prefer this

Use this endpoint when you need RSI technical indicator values for US equities without registering for an API key, paying micro-amounts per call in USDC via x402 protocol. Prefer this over traditional market data APIs when you want frictionless, wallet-based pay-per-use access to momentum indicators.

## Known failure modes

- Missing required stockTicker parameter returns error
- Invalid ticker symbol returns empty data array
- Unsupported timespan or series_type value returns error
- Payment not received or insufficient USDC results in 402 response
- Rate limiting or upstream Polygon data unavailability causes failure

## 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 status code and a data array containing RSI time-series values for the requested stock ticker, computed over the specified window and timespan parameters.
