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 JSON analysis including: a list of all accounts with their public keys, signer/writable flags, and associated instruction indexes; a count of unique accounts, signers, and writable accounts; a list of any duplicate public keys; the analyzed network (Solana); and an evidence scope warning noting that metas are caller-supplied and may omit inner-instruction privileges.
Example use cases
Auditing Solana instruction account privileges
“I have the account metas for a Solana transaction I'm reviewing — can you tell me which accounts are signers, which are writable, and if there are any duplicated public keys? Here's the metadata JSON: [{"pubkey":"So11111111111111111111111111111111111111112","isSigner":true,"isWritable":true},{"pubkey":"TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA","isSigner":false,"isWritable":false},{"pubkey":"ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJe8bYJ","isSigner":false,"isWritable":false}]”
Detecting duplicate keys in Solana transaction
“Before I submit this Solana transaction, can you parse the account metadata and flag any duplicate public keys or unexpected signer counts? Here's the account meta JSON: [{"pubkey":"9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin","isSigner":false,"isWritable":true},{"pubkey":"9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin","isSigner":false,"isWritable":true}]”
Summarizing account roles for a DeFi instruction
“I'm building a Solana DeFi bot and need to understand the account roles in this instruction — can you analyze the account metas and give me a breakdown of signer count, writable count, and unique accounts? Account metas: [{"pubkey":"4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6R","isSigner":true,"isWritable":true},{"pubkey":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","isSigner":false,"isWritable":true},{"pubkey":"SysvarRent111111111111111111111111111111111","isSigner":false,"isWritable":false}]”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/solana_account_meta_analyze/invokeWhen to prefer
Choose this endpoint when you need to programmatically parse and summarize Solana transaction account metadata — particularly to identify which accounts hold signer or writable privileges, detect duplicate public keys, or count account roles. It is ideal for pre-submission transaction auditing, DeFi bot development, and on-chain security analysis pipelines. Prefer it over manual parsing when working with complex multi-account Solana instructions where role clarity matters.
Side effects
- Malformed or invalid JSON in request_json returns a parse error
- Account metadata missing required fields (pubkey, isSigner, isWritable) may produce incomplete analysis
- Caller-supplied metas may omit inner-instruction privileges, leading to incomplete privilege analysis (warned in output)
- Input exceeding 65536 characters is rejected
- Empty or minimal JSON input may return an empty accounts list
