How this service works
Use right before signing a transfer your agent built from an instruction like "send 5 USDC to X". Confirms the transaction moves exactly that token, amount and recipient and nothing else, catching hallucinated amounts, wrong decimals and injected instructions.
Output
Returns a verification result indicating whether the transaction exactly matches the intended token, amount, recipient, and contains no unexpected instructions. Flags specific discrepancies such as hallucinated amounts, incorrect decimal encoding, wrong recipient addresses, or injected extra instructions.
Example use cases
Pre-sign USDC transfer guard
“I told you to send 10 USDC to wallet 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU — before you sign anything, verify the transaction you built actually sends exactly 10 USDC to that address and hasn't hallucinated a different amount or slipped in extra instructions.”
Detecting injected instructions
“Double-check this Solana transaction before signing — I asked you to send 1 SOL to my friend's wallet but I want to make sure nobody injected any extra program calls or changed the recipient address.”
Wrong decimals prevention on token send
“I'm about to send 50 BONK to address 3yFwqXBfZY4jVbmFXdGW4jf6nFQkx2JhP9sP2WrKhJtW, but I want you to verify the transaction has the right decimal conversion for BONK and the amount isn't off by a million due to a decimals mistake before you sign it.”

Endpoint
POSThttps://solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/check_transaction_intent?utm_source=zero.xyzWhen to prefer
Use this endpoint specifically when an AI agent has constructed a Solana token transfer transaction from a natural language instruction and needs to verify it before signing — particularly to catch LLM hallucinations around amounts, decimal encoding errors, wrong recipients, or prompt-injection attacks that may have altered the transaction. Prefer this over general transaction simulation when the goal is intent verification rather than balance impact preview.
Side effects
- Transaction cannot be decoded or is malformed — returns error
- Expected parameters do not match any instruction in the transaction — returns mismatch with details
- Token mint address unrecognized — may return inconclusive result
- Network or service unavailability — returns HTTP error
- Ambiguous multi-instruction transaction may produce uncertain match result
