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).
Example use cases
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.”
Technical details
Endpoint
POSThttps://api.solprobe.xyz/exit/cross-checkWhen to prefer
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.
Side effects
- 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
