# KeeperHub Emporia CBRI Score - Stablecoin Depeg Risk Scorer

> KeeperHub Emporia CBRI Score - Stablecoin Depeg Risk Scorer is a paid API for AI agents from app.keeperhub.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Computes a composite blockchain risk index (CBRI) score for a Uniswap v3 pool using order-flow imbalance, depeg, and liquidity-drain signals to detect stablecoin depeg risk.

## 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 keeperhub-emporia-cbri-score-stablecoin-depeg-risk-scorer-24b879d6 -d '<json body>'
```

Example prompt: Score the depeg risk on the USDC/ETH Uniswap v3 pool at 0xabc...123 — token0 is USDC (6 decimals) at 0xA0b...eB48, token1 is WETH (18 decimals) at 0xC02...6Cc2, and use the USDC/USDT depeg reference pool at 0xdef...456, with 5-minute candles, a drain threshold of 0.05 and depeg threshold of 0.01.

## When to prefer this

Use this endpoint when you need a quantitative, multi-signal composite risk score for a specific Uniswap v3 stablecoin pool — particularly when you want early-warning drain detection combined with depeg confirmation in a single automated workflow. Prefer this over generic on-chain data queries when you want a pre-calibrated noisy-OR scoring model rather than raw price or liquidity feeds.

## Known failure modes

- Missing required addresses (poolAddress, token0Address, token1Address, depegPoolAddress) returns a validation error
- Partial drain window data causes an inflated/invented drain spike — ensure drainWindow candles are fully available
- Wrong token decimals silently rescale the drain signal, producing incorrect scores
- Misconfigured sigmoid parameters (steepness/threshold) can suppress or over-amplify signals
- Pool address not indexed on-chain returns a data-unavailable error
- Network congestion may delay execution result availability

## How this service works

Build powerful blockchain workflow automations with a visual, node-based editor. Built with Next.js and React Flow.

## Output

Returns a JSON object with a run status ('running') and an executionId that can be used to poll for the completed composite CBRI score, individual signal values (depeg, drain, OFI), and whether the firing threshold was exceeded.
