# PoolProof Exit Cost

> PoolProof Exit Cost is a paid API for AI agents from poolproof.qalibr.ru:7443, paid per call via x402, $0.01/call, status down (last checked 2026-09-01).

Calculates the real cost of exiting a Solana liquidity position at a specified size by routing a live trade quote rather than using theoretical slippage estimates

## 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 poolproof-exit-cost-e99e470e -d '<json body>'
```

Example prompt: What will it actually cost me to exit my 50,000 USDC worth of SOL/USDC position on Solana right now — give me the live routed exit cost with any size wall or liquidity flags?

## When to prefer this

Use this endpoint when you need a live, routed exit cost for a specific Solana position size — not a theoretical slippage estimate. Prefer this over static slippage calculators or TVL-based estimates when the actual trade size matters and you need real-time routing to detect size walls or abnormal exit costs before committing to an exit.

## Known failure modes

- Invalid or unsupported token pair returns an error or failed ok status
- Position size too large for any routing path may return SIZE_WALL flag
- Network or RPC issues with Solana may cause stale or unavailable quotes
- Missing required fields (position size, token identifiers) causes request rejection
- Illiquid pools may return unreliable EXIT_COST estimates with appropriate flags

## How this service works

Real cost of exiting a Solana position AT YOUR SIZE — live route, not theoretical slippage

## Output

Returns a JSON object with an 'ok' boolean indicating success, a 'verdict' string summarizing the exit cost assessment, an array of 'flags' (each with a code like SIZE_WALL or EXIT_COST and a message), and a 'disclaimer'. Empty flags array means no issues were detected. The verdict reflects the live-routed actual cost of exiting the position at the specified size.
