## 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 deltasignal-alpha-signals-adf0cc5e
```

Example prompt: Pull the DeltaSignal phase 1 alpha, resilience, treasury-strength, and regime-fit signals for MSTR as of 2024-11-01.

## When to prefer this

Use this endpoint when you need deterministic, quantitative investment signals specifically for crypto public companies — covering alpha, resilience, treasury-strength, and regime-fit in a single call. Prefer this over generic financial data APIs when you need crypto-native scoring methodology rather than traditional fundamental analysis.

## Known failure modes

- Unknown or unsupported ticker returns a 404 or empty signal object
- Invalid date format for source_date (not YYYY-MM-DD) returns a 400 validation error
- Ticker not covered by DeltaSignal universe returns no signal data
- Payment not processed (x402 protocol failure) blocks access
- Service temporarily unavailable on canary deployment returns 503

## How this service works

Deterministic Phase 1 alpha, resilience, treasury-strength, and regime-fit signals for one issuer.

## Output

Returns a structured object containing deterministic phase 1 signals for the requested issuer, including alpha score, resilience metric, treasury-strength indicator, and regime-fit score, optionally scoped to a specific scoring slice date.
