## 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 mycelia-signal-regime-persistence-oracle-d881d42e
```

Example prompt: What's the current BTC perp market regime, how many hours has it been running, and where does that put us historically — is this an unusually long regime or pretty typical?

## When to prefer this

Use this endpoint when you need historical context on how long the current perp market regime has been running and how unusual its duration is — particularly for trading strategy timing, regime-change anticipation, or risk management. Prefer this over generic market data endpoints when you need the specific combination of regime label, duration percentile, and remaining-time estimate in one signed, auditable response.

## Known failure modes

- Unsupported currency parameter returns error — only BTC, ETH, SOL are supported
- Missing currency param may default or return 400 bad request
- Signing/attestation failure if oracle backend is degraded
- Stale regime data if upstream market feed is delayed
- Payment failure (402) if USDC balance insufficient for $0.15 per-call fee

## How this service works

Regime Persistence — historical context for current perp regime duration. Returns current regime, duration_hours, historical_percentile, typical_remaining_hours based on median of all historical runs. BTC/ETH/SOL via ?currency= param. Layer 3 Oracle Intelligence. — Ed25519 signed attestation

## Output

Returns the current perpetual futures market regime label, the number of hours it has been active (duration_hours), its historical percentile rank among all past regime runs (historical_percentile), and the typical remaining hours based on the median of all historical runs of that regime type. Response is Ed25519 signed for attestation integrity.
