## 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-calculator-fb811a8d -d '<json body>'
```

Example prompt: What will it actually cost me to exit my 50,000 USDC position in this Solana token right now — check the live route and tell me if there's a size wall or any exit cost flags I should know about.

## When to prefer this

Use this endpoint when you need a live, size-aware exit cost quote for a Solana position — not theoretical slippage estimates. It is the right choice when position size is large enough to matter (i.e., you could move the market), when evaluating pump.fun or low-cap tokens with thin liquidity, or when you need explicit SIZE_WALL and EXIT_COST flag signals before executing a trade. Prefer it over generic price feeds or TVL metrics when the question is specifically 'what will I actually receive if I sell right now at this exact size?'

## Known failure modes

- Token address not found or not a valid Solana token — returns ok:false with error flags
- Position size too large for any available route — SIZE_WALL flag raised
- Network or RPC issues preventing live route fetch — ok:false response
- Missing required input fields — malformed request error
- Token has no active liquidity pools — router returns no viable exit path

## How this service works

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

## Output

A JSON object with an 'ok' boolean indicating success, a 'verdict' string summarizing the exit assessment, an array of 'flags' (each with a code like SIZE_WALL or EXIT_COST and a message), and a 'disclaimer'. Together these tell you the real-world cost and feasibility of exiting your position at the requested size using a live DEX router quote.
