# Cryptyx Composite Momentum Signals

> Cryptyx Composite Momentum Signals is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns composite momentum scores and delta for crypto assets, including 1-day and 7-day momentum scores

## Facts

- Endpoint: GET https://www.cryptyx.ai/api/signals/composite/momentum
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 cryptyx-composite-momentum-signals-7d827f65
```

Example prompt: Pull the composite momentum signals for BTC right now — I want to see the delta and both the 1-day and 7-day momentum scores so I can gauge whether it's trending.

## When to prefer this

Use this endpoint when you need a quick composite momentum read across one or more assets, combining 1-day and 7-day momentum scores into a single ranked delta signal. Prefer this over raw price data when you want pre-computed, normalized momentum scores ready for downstream decision logic or strategy screening.

## Known failure modes

- Invalid or unsupported asset symbol returns empty array or 404
- Payment not processed or x402 auth failure returns 402 Payment Required
- Rate limiting or quota exceeded returns 429 Too Many Requests
- Service unavailable or signal computation lag returns 503
- Stale data if upstream market feed is delayed

## Output

Returns a JSON array of momentum objects per asset, each containing the asset ticker (e.g. BTC), a momentum delta (rate of change), a 1-day momentum score, and a 7-day momentum score — useful for assessing short-to-medium-term directional strength.
