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.
Example use cases
RSI check for crypto prices
“I have the last 6 daily closing prices for Bitcoin: 28000, 28500, 28200, 29000, 29800, 30000. Can you calculate the RSI, momentum, and moving averages for me?”
Volatility screening for equities
“Run the quant indicators on these AAPL closing prices — 170, 172, 169, 175, 178, 177 — and tell me the annualized volatility and max drawdown.”
Momentum check before rebalancing
“Before I rebalance my portfolio, can you compute the 3-period and 5-period moving averages and momentum percentage for this ETF price series: 50, 51, 52, 53, 54, 55?”
Technical details
Endpoint
POSThttps://x402.feld-feder.at/v1/quant/indicatorsWhen to prefer
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.
Side effects
- 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
