check_solana_transaction
Use before signing an unsigned Solana transaction, not for a token mint alone. Provide a real unsigned Solana transaction serialized as base64, with optional signer and expected intent. Malformed input is rejected before payment. Simulation returns ALLOW, WARN or BLOCK with reasons and balance changes. Optional idempotency_key is random 32-byte base64url. A signed call waits up to 20 seconds for analysis and can settle without a key. If still processing, echo the unpaid job_id with the same proof and arguments when ready. get_job_result reports processing and retry_after_s for free; the result appears there only after settlement. Costs $0.01 USDC via x402.
