SolMachina Transaction Inspector
x402
SolMachina Transaction Inspector is a paid API for AI agents from api.solmachina.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Decodes and analyzes a Solana transaction by signature, returning success status, fee, programs invoked, SOL/token balance changes, and compute units consumed

How this service works
Before an AI agent executes on Solana, it asks SolMachina: risk + a decision (EXECUTE/REVIEW/REJECT) + an SMRI score + a signed receipt, paid per call over x402 in USDC. Trust-first — cites every source, says 'unknown' over guessing. No account, no API key.
Output
Returns a structured object with: a boolean success flag, the transaction fee in SOL, an array of programs invoked (with names), arrays of SOL and token balance changes per account, and the compute units consumed. Every field is source-cited and no confidence values are fabricated.
Example use cases
Verify DeFi swap outcome
“I just made a swap on Solana — can you inspect transaction 3rQmPpLkXz9vD7YjNwBtFgHsA2eVcR4oUqTmKiLbE8n and confirm it succeeded, what tokens changed, and how much it cost in fees?”
Debug failed Solana transaction
“This Solana transaction seems to have failed — can you decode 4yKpNnMzBx6wE8ZhQvCrJsT3fWdYgU5oRqAiLcP9mV2 and tell me what programs were invoked and how many compute units it consumed so I can figure out what went wrong?”
Audit wallet transaction history
“For compliance purposes, can you pull the full breakdown of Solana transaction 2mFtRrLsXw8vN9YkPqBuHdA4eZcS5oTqKiMbD7jE6n — I need to know every SOL and token balance change and which programs were called?”
Technical details
Endpoint
GEThttps://api.solmachina.com/v1/tx-inspectWhen to prefer
Choose this endpoint when you need a structured, human-readable decode of a specific Solana transaction by its signature — including program names, balance deltas, and success status — without setting up an account or API key. It is ideal for AI agents that need on-demand, per-call transaction intelligence paid in USDC via x402, particularly in DeFi audit, compliance, or debugging workflows where fabricated data is unacceptable.
Side effects
- Invalid or malformed Base58 signature returns an error
- Transaction signature not found on Solana mainnet (e.g. devnet tx) returns not-found error
- Very recent transactions may not yet be indexed, causing a temporary unavailability
- Payment of 0.01 USDC via x402 fails or is rejected, blocking the request
- Network timeout if Solana RPC is congested
