# DeltaSignal ATLAS-7 Calculation History

> DeltaSignal ATLAS-7 Calculation History is a paid API for AI agents from api.aitrailblazer.net, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-15).

Retrieves historical ATLAS-7 alpha, risk, and covenant-stress calculation records for crypto-adjacent public companies, filterable by ticker, CIK, and date range.

## Facts

- Endpoint: GET https://api.aitrailblazer.net/v1/atlas7/calculation-history
- Price: $0.2/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 deltasignal-atlas-7-calculation-history-70830745
```

Example prompt: Pull the ATLAS-7 calculation history for MSTR — give me the last 10 records in compact mode, covering source dates from 2026-01-01 to 2026-05-08.

## When to prefer this

Use this endpoint when you need a time-series or historical view of ATLAS-7 signals for one or more crypto-adjacent public companies (e.g. MicroStrategy, Marathon Digital). Prefer this over the single-issuer signal endpoint when you need multiple past calculations, trend analysis, or audit-trail verification via payload SHA-256. Best for date-range queries and compliance/research workflows.

## Known failure modes

- Unknown ticker or CIK returns empty data array with status ok
- Invalid date format for source_date/source_date_from/source_date_to returns a 400 or empty result
- limit parameter out of range may return default row count
- Missing required input wrapper causes schema validation error
- Payment not completed (x402) results in 402 Payment Required response

## How this service works

Complete ATLAS-7 calculation-history rows for issuer/source-date slices, including covenant, fundamentals, peer, alpha, market regime, SPECTRA inputs, provenance, and hashes.

## Output

Returns a JSON array of ATLAS-7 calculation records, each containing the issuer's CIK, ticker, risk tier (e.g. LOW/MED/HIGH), numeric alpha score (0–100), source date, SHA-256 payload hash, and covenant stress metrics (e.g. live_stress_50pct). Also includes status, payload mode, and method version fields.
