## 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-first-ever-setup-fires-86c4dda0
```

Example prompt: Pull today's first-ever CRYPTYX setup fires — I want to see which signals have never fired before across the full asset universe.

## When to prefer this

Use this endpoint when you specifically want the rarest, most historically unprecedented signal events — setups that have never fired before. Prefer this over the general daily setup evaluation endpoint when novelty and first-occurrence are the primary filter criteria, and when you want to surface the highest-signal anomalies rather than all firing setups.

## Known failure modes

- Invalid asof_day format returns a 400 error
- If no first-ever setups fired on the requested day, returns an empty result set
- Payment not attached or invalid x402 header results in a 402 Payment Required response
- Future dates or dates before catalog inception may return errors or empty results

## How this service works

First-ever fires — setups that fired for the FIRST TIME in prospective history. Rarest, highest-signal events in the canonical catalog. A setup with state = first_ever has never fired before since it was added. Historical backtest reflects behaviour on ADJACENT setups or partial configurations, not this exact combo — treat as structurally important context, not directional recommendations. Applicable across the CRYPTYX 200+ asset coverage universe (BTC, ETH, SOL, top-cap + long-tail); backtested scope is the 33-asset curated slice.

## Output

A list of canonical setups with state = 'first_ever', meaning each has never fired before since being added to the CRYPTYX catalog. Each record includes setup identifiers, the asset(s) involved, and structural backtest context drawn from adjacent or partial configurations (not the exact combo). Covers CRYPTYX's 200+ asset universe with backtested data anchored to a 33-asset curated slice.
