# X402 Quantitative Technical Indicators

> X402 Quantitative Technical Indicators is a paid API for AI agents from x402.feld-feder.at, paid per call via x402, $0.005/call, status down (last checked 2026-09-15).

Computes quantitative technical indicators (RSI, momentum, moving averages, volatility, max drawdown) for a price series, pay-per-request via x402 micropayment.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-quantitative-technical-indicators-e2c7fc70 -d '<json body>'
```

Example prompt: Compute technical indicators — RSI, momentum, simple moving averages, max drawdown, and annualized volatility — for these closing prices: [100, 102, 101, 104, 106, 106].

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-use quantitative technical indicator computation without subscribing to a heavyweight financial data platform. It is ideal for AI agents that need on-demand RSI, momentum, SMA, volatility, and drawdown metrics from a user-supplied or agent-gathered price series, and when micropayment via x402/USDC is acceptable. Prefer this over broker APIs or Bloomberg-style feeds when you already have the price data and simply need the derived indicators computed.

## Known failure modes

- Insufficient data points in price series — RSI and moving averages require a minimum number of observations
- Invalid or malformed price array — non-numeric values cause computation failure
- Payment failure or insufficient USDC balance — x402 micropayment rejected, request not processed
- Empty price series submitted — endpoint returns error with no indicators computed
- Network timeout or service unavailability at x402.feld-feder.at

## How this service works

Pay-per-request data tools for AI agents.

## Output

Returns a JSON object containing: RSI value, latest close price, momentum percentage for multiple lookback windows, simple moving averages for multiple windows, annualized volatility percentage, max drawdown percentage, number of observations, and a research disclaimer. All values are deterministic calculations based on the submitted price series.
