# TruthBear AI Dataset Takedown Gauge

> TruthBear AI Dataset Takedown 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 3-leg sequential chain signal tracking the takedown lifecycle of a specific AI training dataset — from access pressure and legal notices through current availability to final disposition (gated, withdrawn, or deleted).

## Facts

- Endpoint: GET https://api.truthbear.co/gauge/aidataset-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-dataset-takedown-gauge-a153e7ce
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_tNCybhpHKCixNw5t66vBk

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-dataset-takedown-gauge-a153e7ce
```

Example prompt: What's the current takedown status of the LAION-5B dataset — is it still accessible, under legal pressure, or has it been gated or withdrawn?

## When to prefer this

Use this endpoint when you need a structured, sequential chain assessment of an AI training dataset's takedown lifecycle — from legal pressure through final disposition — sourced from host registries and official notices. Prefer this over general web search when you need a standardized, confidence-scored signal rather than unstructured news. Not suitable for forecasting or legal advice.

## Known failure modes

- 422 no_charge returned when no data exists for the requested entity — caller is not billed
- Invalid or unrecognized entity ID returns an error — use GET /gauge/catalog?signal_id=<signal_id> to retrieve the accepted entity list
- Network or upstream registry unavailability may delay or block readings

## How this service works

[3-LEG] AI dataset takedown chain, one dataset (?entity=laion-5b): leading access pressure from gating and legal notices -> current current availability -> realized lifecycle to gated, withdrawn or deleted (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: host registries and official notices. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.

## Output

A JSON object representing a 3-leg sequential confidence chain: leg 1 is leading access pressure (gating pressure, legal notices); leg 2 is current availability status; leg 3 is realized lifecycle disposition (gated, withdrawn, or deleted). Confidence score reflects how many legs are confirmed in order. Returns 422 with no charge if no data is available for the requested entity.
