# AI Dependency Deprecation Risk Gauge

> AI Dependency Deprecation 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 2026-09-15).

Returns lifecycle and deprecation risk signals for a named AI model, API, or SDK — including sunset dates, official deprecation notices, and cascading dependency exposure.

## Facts

- Endpoint: GET https://aeml-x402.zeabur.app/gauge/dependency-region
- Price: $0.25/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ai-dependency-deprecation-risk-gauge-5068855d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_F-9Hy_WUTItTO_7kw0dKI

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 ai-dependency-deprecation-risk-gauge-5068855d
```

Example prompt: Can you check the deprecation status and lifecycle timeline for openai-text-davinci-003 — I want to know if there's an official sunset notice, how long it survived, and whether any AI tools depending on it are at risk?

## When to prefer this

Choose this endpoint when you need a single structured pull of an AI model's, API's, or SDK's full deprecation lifecycle — especially when you need official sunset notices, survival day counts, migration guide references, and cascade risk signals in one verifiable response. Prefer this over general web search when you need machine-readable, cryptographically citable provenance for compliance or automated monitoring workflows.

## Known failure modes

- Unknown entity returns no lifecycle data or empty legs
- Entity not found in tracked index returns an error or null result
- Stale data may be flagged via freshness field as 'stale' when official sources haven't updated
- No official deprecation page exists for some models, limiting notice data
- Payment failure (x402) blocks access before any data is returned
- 422 returned when entity has no applicable signals

## How this service works

[3-LEG] AI dependency chain, one dependency (?entity=openai-text-davinci-003): leading deprecation notices INCLUDING the sunset date the publisher itself scheduled -> current current availability -> realized lifecycle to deprecation, days alive (confirmation gate). A sequential chain, not one reading - confidence = how many legs are lit, in order. Sources: vendor notices, source URL per record. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.

## Output

A structured JSON object containing: lifecycle status (launch to deprecation/sunset with survival days), official deprecation notices and migration guide references, cascade exposure signals for dependent AI tools, a cross-line narrative comparing signals, provenance metadata with freshness indicators, verifiable record hashes, and an Ed25519-signed citation for zero-trust verification.
