# CRYPTYX Harness Snapshot

> CRYPTYX Harness Snapshot is a paid API for AI agents from cryptyx.ai, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns a canonical orientation tear-sheet for crypto assets — totals counts, top-5 fires by confidence, first-ever prints, boundary watchlist, and silent fade setups — in a single call.

## Facts

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-harness-snapshot-801c5be2
```

Example prompt: Give me the CRYPTYX harness snapshot for all 33 assets as of today — I want to see total setup counts, the top fires by confidence, anything printing a first-ever signal, and which assets are on the boundary watchlist.

## When to prefer this

Use this endpoint as the first call in any crypto analysis workflow — it is explicitly designed as the canonical orientation layer before drilling into attribution, regime context, or raw metric data. Prefer it when you need a fast, cheap, high-level summary across multiple setup types (fires, boundary, silent, first-ever) without querying multiple specialized endpoints. It is the lowest-cost entry point at $0.005 per call, making it viable for polling loops. Use sibling endpoints for per-asset attribution waterfalls, cross-sectional metric scans, or raw time-series data.

## Known failure modes

- Invalid scope string returns 400 — must be 'apex', 'all', or 'asset:{SYMBOL}' format
- Unknown asset symbol in asset:{SYMBOL} scope returns error or empty result
- Invalid asof_day format (not YYYY-MM-DD) causes request failure
- Day with no evaluated data (future date or missing evaluation run) may return empty totals
- Payment failure (x402) returns 402 before any data is served
- Rate limiting if polling frequency exceeds economically modeled thresholds

## How this service works

Canonical harness tear-sheet — one call returns totals (fires / boundary / silent / first-ever), top-5 fires by confidence, first-ever prints (5-year rarity), boundary watchlist (near-fire ranked by distance-to-trigger), and silent fade setups. Every setup carries plain-English composition (via ref.metric_display_labels) so responses never leak raw metric_id strings. Priced cheap so polling patterns stay economically viable — every MCP skill instructs Claude to call this FIRST as the canonical orientation. Scope: apex (BTC/ETH/SOL default), all (33-asset curated universe), or asset:{SYMBOL} for single-asset lens.

## Output

A structured tear-sheet containing: (1) aggregate setup counts across fire/boundary/silent/first-ever categories, (2) top-5 setups ranked by confidence with plain-English metric labels, (3) first-ever prints flagged as 5-year rarities, (4) a boundary watchlist of near-trigger assets sorted by distance-to-trigger, and (5) silent fade setups — all with human-readable metric composition via ref.metric_display_labels so no raw metric IDs are exposed.
