# SmallSat Constellation Liveness & Deorbit Risk Gauge

> SmallSat Constellation Liveness & Deorbit Risk Gauge is a paid API for AI agents from aeml-x402.zeabur.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).

Returns a multi-leg due-diligence gauge for a named small satellite constellation covering operator lifecycle, spectrum license milestones, and orbital decay/survival ratio with cross-validated narrative.

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-liveness-deorbit-risk-gauge-8edd5cb0
```

Example prompt: Can you pull the full liveness triangle for OneWeb — operator lifecycle, FCC/ITU spectrum license status, and how many satellites are still in orbit versus deorbited — so I can decide whether to commit to a multi-year data contract with them?

## When to prefer this

Choose this endpoint when you need a verifiable, multi-source triangulated view of a specific small satellite constellation's operational status — especially when a company's corporate health and fleet physical liveness may diverge (e.g. bankrupt operator with satellites still flying). Prefer over generic news searches or single-source checks when satellite data purchase decisions, insurance underwriting, or integration contracts require offline-verifiable provenance tied to official orbital catalogs and spectrum regulators.

## Known failure modes

- Unknown or misspelled entity key returns error or empty legs
- Constellation with no public TLE data (classified or too new) may have incomplete orbital leg
- Spectrum license data may lag actual FCC/ITU actions by days to weeks
- Company still legally operating but fleet fully deorbited — narrative flags but may confuse callers expecting binary alive/dead
- Freshness marked stale if official orbital catalog not updated recently
- Payment failure (x402 USDC) results in 402 response before any data is returned

## 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 sequential 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.

## Output

A structured multi-leg gauge object containing: operator/constellation lifecycle status (deployment through bankruptcy/deorbit), spectrum license milestone flags (FCC/ITU bring-into-use compliance or revocation), orbital survival ratio from Space-Track/CelesTrak TLE data, cross-line narrative reconciling all three legs, freshness/provenance metadata with cadence-aware staleness assessment, and an Ed25519-signed offline-verifiable citation anchoring claims to official sources.
