# CRYPTYX Near-Fire Watchlist

> CRYPTYX Near-Fire Watchlist is a paid API for AI agents from cryptyx.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns queued trading setups ranked by proximity to trigger threshold (distance-to-fire in sigma units), enabling cheap polling for imminent signal detection across 200+ crypto assets.

## Facts

- Endpoint: GET https://cryptyx.ai/api/v1/harness/watchlist
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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-near-fire-watchlist-1118a323
```

Example prompt: Check the CRYPTYX near-fire watchlist and show me the top 15 setups closest to triggering as of today, ranked by how close they are in sigma distance.

## When to prefer this

Choose this endpoint over /api/v1/harness/evaluations when you only care about which setups are closest to firing and want to minimize cost — it is explicitly cheaper and designed for 15-30 minute polling intervals. Prefer this for autonomous agent monitoring loops where full evaluation detail is unnecessary. Use the full evaluations endpoint only when you need complete state breakdowns (fires/boundary/silent/failed) for all setups on a given day.

## Known failure modes

- Invalid asof_day format (non-YYYY-MM-DD) returns a 400 error
- limit exceeding 50 is clamped or rejected
- Requesting a future asof_day returns no data or an error
- Payment failure (x402) results in 402 response requiring USDC payment
- No near-fire setups exist for the requested day returns an empty list

## How this service works

Near-fire setups ranked by distance-to-trigger DESC (closest to firing first). Primary monitoring surface for autonomous agents — cheap to poll at 15-30 min intervals to detect when a queued setup is about to fire. Distance in sigma; 0.2 means one metric is 0.2σ from its threshold. Cheaper than polling /api/v1/harness/evaluations when you only care about near-fires. Applicable across the CRYPTYX 200+ asset coverage universe (BTC, ETH, SOL, top-cap + long-tail); backtested scope is the 33-asset curated slice.

## Output

An ordered list of queued trading setups (up to 50) ranked by distance-to-trigger in descending order (closest to firing first), where each entry includes the asset identifier, the distance in sigma units, and setup metadata. Distance of 0.2 means one metric is only 0.2σ away from its threshold. Coverage spans 200+ assets with a backtested curated slice of 33 assets.
