# Miorail B20 Exit Analysis

> Miorail B20 Exit Analysis is a paid API for AI agents from miorail.xyz, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-16).

Analyzes exit liquidity capacity and feasibility for a given Base chain token (B20), returning a verdict on measurable exit conditions.

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 miorail-b20-exit-analysis-c7260174
```

Example prompt: Can you run an exit analysis on the Base token at contract address 0x1234...abcd and check if I can exit a $500 USDC position without issues?

## When to prefer this

Use this endpoint when you need to assess whether a specific Base chain token has verifiable exit liquidity — particularly before entering or managing a position. It is purpose-built for B20 token exit analysis with optional USDC position-size comparison, making it more specific than generic DEX liquidity checkers. Prefer it when you need a structured verdict with explicit evidence flags rather than raw liquidity numbers.

## Known failure modes

- Missing or invalid tokenAddress returns a validation error
- Token contract not found on Base chain returns no analysis data
- Position size provided but no measured data available at that scale results in missing evidence entries
- Network or upstream data unavailability may result in incomplete verdict
- Invalid contract address format causes request rejection

## Output

Returns a JSON object with the service name, an analysis object containing a verdict with a status field (e.g. 'measured'), and a missingEvidence array listing any gaps in exit capacity evidence — such as whether exit capacity above the largest measured size is established.
