# SolProbe Exit Cross-Check

> SolProbe Exit Cross-Check is a paid API for AI agents from api.solprobe.xyz, paid per call via x402, $0.01/call, status down (last checked 2026-09-15).

Checks whether a Solana token can be profitably exited and bridged to a home EVM chain, returning all-in cost breakdown and a buy/sell recommendation.

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 solprobe-exit-cross-check-5201b062 -d '<json body>'
```

Example prompt: Check if I can cleanly exit $200 worth of this Solana token (address: 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAss) and bridge the proceeds to Base — tell me the all-in cost, price impact, and what I'd net.

## When to prefer this

Use this endpoint when an AI agent needs to evaluate whether a Solana token position can actually be liquidated and the proceeds moved to an EVM chain, including realistic cost modeling. Prefer this over generic DEX APIs when you need combined sell-and-bridge cost analysis in a single call with no account setup.

## Known failure modes

- Token address not found or invalid — returns error or low data_quality signal
- No bridge route available to the requested home chain — bridge.available: false
- Extremely low liquidity causes price impact too high to estimate accurately
- Unsupported home_chain value — validation error
- Payment failure via x402 — 402 response before data is returned

## How this service works

AI-callable Solana token intelligence. Pay per call via x402 USDC on Base or Solana, or Virtuals ACP escrow. No accounts, no keys, no subscription.

## Output

Returns a JSON object with: whether the token is sellable, price impact percentage, bridge tool and cost percentage, estimated bridge duration in seconds, all-in cost percentage, expected and net output in USDC on the home chain, a data quality indicator, and a plain-language recommendation (action: OK or warning + reason string).
