# aiworker-data Technical Indicators (Base Token)

> aiworker-data Technical Indicators (Base Token) is a paid API for AI agents from aiworker.duckdns.org, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Computes standard technical indicators (RSI 14, EMA 20/50, SMA 20, Bollinger Bands, ATR 14, high/low, percentage changes) for a Base chain token using GeckoTerminal OHLCV candle data from its largest liquidity pool.

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 aiworker-data-technical-indicators-base-token-211dd95e -d '<json body>'
```

Example prompt: Pull the hourly technical indicators for the Base token at 0x532f27101965dd16442e59d40670faf5ebb142e4 using 100 periods — I want RSI, EMAs, Bollinger Bands, ATR, and the recent percentage changes.

## When to prefer this

Use this endpoint when you need deterministic, reproducible technical indicator values for a Base chain token and want to avoid running the arithmetic yourself. It is ideal when you have a token contract address, need standard TA metrics (RSI, EMAs, Bollinger Bands, ATR) computed from real OHLCV pool data, and want a fast cached result without building your own candle-fetching and indicator pipeline. Prefer this over general market data endpoints when you specifically need indicator values rather than raw price quotes.

## Known failure modes

- Invalid or non-Base token address (must be 0x + 40 hex chars) returns validation error
- Token has no liquidity pool on Base — GeckoTerminal returns no OHLCV data
- Periods out of range (below 50 or above 200) returns schema validation error
- GeckoTerminal API unavailable causes upstream data fetch failure
- Token exists but pool has insufficient candle history for the requested period count

## How this service works

Technical indicators for one Base token from its largest pool's candles (GeckoTerminal OHLCV, hourly or daily, 50–200 periods): RSI 14, EMA 20/50, SMA 20, Bollinger bands 20/2σ, ATR 14, last close, high/low and percentage changes — the textbook arithmetic on past prices, nothing more. Deterministic, no LLM, no signal, no forecast; cached five minutes.

## Output

Returns a JSON object with the computed technical indicators for the token's largest pool: RSI 14, EMA 20, EMA 50, SMA 20, Bollinger Bands (upper/lower/middle/width_pct), ATR 14, last close price, high/low over N periods, 1-period and 24-period percentage changes, pool address, token name/symbol/address, timeframe, candle count, data source attribution, and a disclaimer that these are arithmetic on past prices only. Results are cached for 5 minutes.
