# Cryptyx Recent Signal Firings Stream

> Cryptyx Recent Signal Firings Stream is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a stream of the most recent signal firing events across crypto assets, sorted newest-first, with signal ID, asset, date, triggered status, and confidence.

## Facts

- Endpoint: GET https://www.cryptyx.ai/api/signals/recent
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/cryptyx-recent-signal-firings-stream-28c2cace
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_3EBaGrtKCCj2GRIRHgTxP

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-recent-signal-firings-stream-28c2cace
```

Example prompt: Show me the last 20 signal firing events on Cryptyx — filter for ETH if you can — so I can see what's changed since I last checked.

## When to prefer this

Use this endpoint when you need a reverse-chronological feed of signal firings for change-detection workflows, periodic agent digests, or 'what happened since last run' summaries. Prefer over asset-specific signal endpoints when you want a broad cross-asset view of recent activity rather than deep analysis on a single asset.

## Known failure modes

- Invalid asset symbol returns empty results or 400 error
- Limit parameter exceeding maximum allowed value may return an error or be capped
- Payment not included or insufficient USDC returns 402 Payment Required
- No recent events for the specified asset returns an empty events array
- Service unavailability returns 503 or timeout

## How this service works

CRYPTYX | institutional-grade crypto intelligence: 150+ signals, 440+ metrics, 200+ assets. | Recently triggered atomic signal events from CRYPTYX's 143-signal registry, served from api.v_signals_atomic_ux. Returns up to 50 events as { events: [{ asset, signal_id, confidence, triggered_at }] } where triggered_at is the day-level asof_day, filtered to is_triggered=true. Single query param: since (ISO date, default 24h back, clamped to max 7 days). Ordered by asof_day DESC then asset. Use as a change-detection digest of which atomic signals fired across ~200 assets — pair with /api/signals/catalog or /api/signals/explain to resolve class, geometry, grade, and regime context.

## Output

A JSON object with an 'events' array containing the most recent signal firings, each with signal_id, asset symbol, day (date), triggered (boolean), and confidence score, sorted newest-first.
