SignalHarness Solana V0 Message Analyzer
x402
SignalHarness Solana V0 Message Analyzer is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-13).
Analyzes a serialized Solana versioned (v0) transaction message to extract instruction counts, lookup table usage, key counts, and structural validity warnings.

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 JSON analysis including instruction_count, lookup_count, readonly_lookup_indexes, writable_lookup_indexes, static_key_count, valid_v0 flag, version number, and any structural warnings. Also includes evidence_scope indicating the analysis is based on caller-supplied data, and the analyzed_network (solana). Does not fetch Address Lookup Tables or simulate execution.
Example use cases
Pre-sign Solana transaction validation
“Before I sign this Solana v0 transaction, can you analyze this message JSON and tell me if it's structurally valid, how many instructions it contains, and whether there are any warnings I should know about?”
Inspect address lookup table usage
“I have a Solana versioned transaction message and I need to know exactly which address lookup table indexes it uses — both readable and writable — can you parse this message JSON and give me that breakdown?”
Audit instruction count in transaction
“Can you decode this Solana v0 message and tell me the total instruction count, the static key count, and the version number so I can confirm it matches what my dApp constructed?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/solana_v0_message_analyze/invokeWhen to prefer
Use this endpoint when you need fast, stateless structural analysis of a Solana v0 (versioned) transaction message without executing it on-chain. Ideal for pre-signing inspection, instruction auditing, or lookup table mapping. Note: it does not fetch Address Lookup Tables or simulate execution, so use on-chain RPC simulation if you need execution-level validation.
Side effects
- Invalid or malformed request_json string causes parsing failure
- Oversized input exceeding 65536 characters is rejected
- Non-v0 transaction format may produce unexpected analysis results
- Missing or empty request_json returns validation error
- Payment failure or insufficient USDC balance returns 402 response
