# TruthBear AI Tool Lifecycle Status Chain

> TruthBear AI Tool Lifecycle Status Chain 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).

Runs a 3-leg sequential chain to assess whether a monitored AI tool is live or dead, using DNS/GitHub checks and lifecycle history with decay warnings and days-alive confirmation.

## Facts

- Endpoint: GET https://api.truthbear.co/gauge/tool-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/truthbear-ai-tool-lifecycle-status-chain-af2c5303
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_iRRp-LqvCW0E0bo0QfwDm

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 truthbear-ai-tool-lifecycle-status-chain-af2c5303
```

Example prompt: Can you check if Cursor is still alive and being maintained — run the full lifecycle chain with DNS and GitHub checks and tell me how many of the three legs are lit?

## When to prefer this

Use this endpoint when you need a structured, multi-signal verdict on whether a specific AI tool or product is still live and actively maintained. It is particularly valuable for due diligence before integration, competitive monitoring, or detecting early decay signals before a product fully shuts down. Prefer this over generic uptime monitors because it combines DNS, GitHub activity, release cadence, and documentation signals into a single confidence-scored lifecycle chain specific to AI tools.

## Known failure modes

- 422 no_charge returned when no data exists for the requested entity — not billed
- Invalid or unrecognized entity slug returns an error
- Entity not in the monitored catalog returns no results
- DNS or GitHub upstream unavailability may reduce confidence or omit legs

## How this service works

[3-LEG] AI tool and MCP chain, one tool (?entity=mammoth-ai): leading decay warnings, release cadence stalling and docs going dark -> current live or dead status from real DNS and GitHub checks -> realized lifecycle from launch to death with days alive (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: DNS, GitHub, package registries. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.

## Output

A sequential 3-leg chain result including: (1) leading decay signals such as release cadence stalling and documentation going dark, (2) current live/dead status from real DNS and GitHub checks, and (3) realized lifecycle data from launch to potential death including days-alive count. Confidence is expressed as the number of legs successfully lit in order. Returns 422 with no_charge if no data is available.
