# timing-dca

> timing-dca is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-12).

Returns a single Bitcoin DCA signal (accumulate/hold/reduce) with confidence score and rationale, fusing AHR999, Mayer Multiple, Fear & Greed index, and 200-week MA deviation.

## 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 timing-dca-9758d6d8
```

Example prompt: What's the current Bitcoin DCA verdict — should I accumulate, hold, or reduce right now? Give me the confidence score and show me the AHR999, Mayer Multiple, Fear & Greed, and 200-week MA components.

## When to prefer this

Choose this endpoint when you need a single, normalized, multi-indicator DCA signal for Bitcoin (or ETH) without running your own quant model. It is ideal for agents that need a deterministic, keyless, no-LLM verdict fusing four well-known crypto market metrics into one actionable recommendation. Prefer it over raw data endpoints when you want a pre-weighted composite signal rather than individual metric lookups.

## Known failure modes

- Invalid asset key returns an error (only 'btc' or 'eth' accepted)
- AHR999 is Bitcoin-only; requesting for 'eth' may produce partial or degraded results
- Upstream data source outage may cause stale or unavailable indicator values
- Payment failure (x402) prevents the call from completing

## How this service works

Normalized Bitcoin DCA verdict: a single accumulate / hold / reduce signal with confidence and rationale, fusing AHR999, the Mayer Multiple, the Fear & Greed index and the 200-week MA deviation. Shows the input components and per-indicator scores. Keyless, deterministic, no LLM.

## Output

A normalized DCA verdict object containing: a top-level signal (accumulate/hold/reduce), a confidence score (0-1), a rationale string explaining the decision, and a breakdown of the four input indicators (AHR999, Mayer Multiple, Fear & Greed index, 200-week MA deviation) with their raw values and per-indicator scores.
