Solana PDA Verification Service
x402
Solana PDA Verification Service is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).
Mathematically verifies whether a given address is a valid Program Derived Address (PDA) on Solana, returning the canonical bump seed and address derivation result.

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 object containing the analyzed address, the computed bump seed, whether the supplied address matches the canonical PDA derivation, any warnings (e.g. that the check is mathematical only and does not inspect on-chain account state), the analyzed network (Solana), and evidence scope. Also includes a full receipt with payment metadata, execution timing, and a SHA256 hash of the result.
Example use cases
Smart contract PDA sanity check
“I just derived a PDA for my Solana program and I want to confirm that address H68a6HmNocBWoDtYo2PDxX3ciRHLUosfsnH9b2r7xNPJ is actually the canonical program derived address — can you verify the bump seed and whether the derivation matches?”
Debugging failed PDA lookup
“My Solana dApp is failing to find an account at the address I computed. Can you mathematically verify if 8Bb7E1hSjoG9rVraQqH6QJ4VYq9vD1g5p7h9oPQx8d3K is a valid PDA for my program ID and tell me what the canonical bump should be?”
Auditing third-party PDA claims
“A third party is claiming this Solana address is a PDA derived from their program — can you run a mathematical verification to check if that derivation is canonical and what bump seed it uses?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/solana_pda_verify/invokeWhen to prefer
Use this endpoint when you need to mathematically verify whether a Solana address is a valid Program Derived Address (PDA) without querying on-chain state. Ideal for smart contract developers, auditors, or agents building Solana integrations who need to confirm correct address derivation and bump seeds. Prefer this over on-chain RPC calls when you only need cryptographic derivation validation, not live account data.
Side effects
- Invalid or malformed JSON in request_json — returns error or unexpected result
- Supplied address does not match any valid PDA derivation — canonical_match returns false
- Missing required seeds or program ID in the request body — may produce incomplete analysis
- Network mismatch if non-Solana parameters are supplied
- Result is mathematical only — does not confirm the account exists on-chain or has been initialized
