How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a structured analysis including a list of changes (account, action, amount, authority, delegate, index), a list of risk flags, the analyzed network (solana), evidence scope (caller_supplied_data), and the service ID. Also includes a receipt with payment and execution metadata.
Example use cases
Pre-signing SPL approval audit
“Before I sign this Solana transaction, can you analyze the SPL token approval instructions in it and flag any suspicious delegate or authority changes? Here's the raw transaction JSON.”
DeFi wallet security check
“I'm building a DeFi wallet and want to warn users before they approve risky token delegations — can you analyze this SPL instruction JSON and tell me what approvals are being granted and whether there are any risk flags?”
Post-incident token approval review
“Someone may have tricked a user into signing a malicious Solana transaction. Can you parse this transaction JSON and show me all SPL token transfers and approvals, including any delegate authorities that were set?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/solana_spl_approval_analyze/invokeWhen to prefer
Use this endpoint when you need to statically analyze caller-supplied Solana SPL token approval or transfer instructions — for example, to audit a transaction before signing, to build wallet security warnings, or to investigate a suspicious transaction. It is a static analysis tool that works on provided data without querying live blockchain state, so prefer it for fast, offline-style checks. It should not be used when you need real-time on-chain authority or allowance lookups.
Side effects
- Malformed or invalid JSON input returns a parse error
- Service explicitly does not query on-chain state, so current authority or allowance accuracy is not guaranteed
- Very large transaction JSON may exceed the 65536-character input limit
- Missing or empty request_json field will fail validation
- Network or payment failures may prevent execution
