# TruthBear LRT Region Gauge – Liquid Restaking Token Risk Chain

> TruthBear LRT Region Gauge – Liquid Restaking Token Risk 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).

Returns a 3-leg sequential risk chain for a specific liquid restaking token (LRT), measuring NAV deviation against ETH, current protocol state, and realized lifecycle impairment/slashing risk.

## Facts

- Endpoint: GET https://api.truthbear.co/gauge/lrt-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-lrt-region-gauge-liquid-restaking-token-risk-chain-527291f6
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_tpGtZtFVq-EM_IIHVu14p

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-lrt-region-gauge-liquid-restaking-token-risk-chain-527291f6
```

Example prompt: Can you pull the TruthBear 3-leg risk chain for Renzo ezETH and tell me the current NAV deviation against ETH, the protocol state, and whether there's any impairment or slashing risk confirmed?

## When to prefer this

Use this endpoint when you need onchain-sourced, descriptive risk assessment for a specific liquid restaking token measured against ETH (not USD), particularly for NAV deviation, protocol state, or impairment/slashing risk. Prefer this over generic DeFi data feeds when you need a structured 3-leg sequential confidence chain rather than a raw price or TVL figure. Not suitable for price forecasting, trading signals, or stablecoin depeg monitoring (use the stablecoin chain endpoint for that).

## Known failure modes

- 422 no_charge returned when no data is available for the requested entity — call is not billed
- Invalid or unrecognized entity identifier results in an error response
- Entity not in the supported list of ~19 monitored LRTs will not return valid data
- Partial chain reading if only some legs have available data, reducing confidence score

## How this service works

[3-LEG] Liquid restaking chain, one LRT (?entity=renzo-ezeth): leading NAV deviation measured against ETH, NOT against one dollar -> current current protocol state -> realized lifecycle to impairment, slashing or wind-down (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: onchain and protocol disclosures. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.

## Output

A 3-leg sequential risk chain JSON object for the specified LRT entity, including: (1) leading NAV deviation measured against ETH, (2) current protocol state, and (3) realized lifecycle status covering impairment, slashing, or wind-down confirmation. A confidence indicator reflects how many legs returned data. Returns HTTP 422 with no charge if no data is available for the entity.
