# Smallsat Constellation Chain — 3-Leg Distress Gauge

> Smallsat Constellation Chain — 3-Leg Distress Gauge is a paid API for AI agents from api.truthbear.co, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).

Returns a sequential 3-leg chain assessment of a smallsat operator's status: financing/deployment stress → current constellation state → realized lifecycle outcome (bankruptcy, wind-down, or deorbit).

## Facts

- Endpoint: GET https://api.truthbear.co/gauge/smallsat-region
- Price: $0.25/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/smallsat-constellation-chain-3-leg-distress-gauge-6c36e786
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_LO0SRhRHLZF8X-bbBQ9VQ

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 smallsat-constellation-chain-3-leg-distress-gauge-6c36e786
```

Example prompt: Pull the TruthBear smallsat constellation chain for OneWeb — I want to see how many of the three distress legs are lit, from financing stress through current constellation state to any wind-down or deorbit confirmation.

## When to prefer this

Use this endpoint when you need a structured, multi-stage distress chain view of a specific smallsat operator grounded in FCC/ITU regulatory filings and operator disclosures — not a forecast but a descriptive, data-anchored chain. Prefer this over generic news searches or financial databases when you want a machine-readable, confidence-scored sequential assessment of a LEO constellation operator's lifecycle stage.

## Known failure modes

- 422 no_charge returned when no data is available for the requested entity — not billed
- Invalid or unrecognized entity ID returns an error; valid IDs can be fetched from GET /gauge/catalog
- Missing required 'entity' query parameter causes request failure
- Partial chain: one or more legs may be unlit if underlying data sources lack current filings

## How this service works

[3-LEG] Smallsat constellation chain, one operator (?entity=oneweb): leading financing and deployment stress -> current current constellation state -> realized lifecycle to bankruptcy, wind-down or deorbit (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: FCC and ITU filings, operator disclosures. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.

## Output

A JSON object with up to three sequential chain legs: (1) leading financing and deployment stress indicators, (2) current constellation operational state, and (3) realized lifecycle outcome such as bankruptcy, wind-down, or deorbit confirmation. A confidence score reflects how many legs are fully supported by data (FCC/ITU filings, operator disclosures). Returns 422 no_charge with no billing if data is unavailable.
