Solana PDA Derivation
x402
Solana PDA Derivation 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).
Derives a Solana Program Derived Address (PDA) and its canonical bump seed from a program ID and seed inputs.

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 the derived PDA address (base58-encoded public key), the canonical bump seed (0-255), any derivation warnings (e.g. noting that existence or ownership of the account is not verified on-chain), and the network analyzed. Wrapped in a standard SignalHarness receipt with execution metadata, request/execution IDs, and a SHA-256 result hash.
Example use cases
Smart contract account address lookup
“I'm building a Solana dApp and need to find the program derived address for my escrow program with ID 'EscrowProgram1111111111111111111111111111111' and the seeds 'user-pubkey' and 'token-mint'. What's the PDA and bump?”
Token vault PDA verification
“Can you compute the canonical PDA address and bump seed for the SPL Token program 'TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA' using seeds 'treasury' and 'usdc'?”
Off-chain PDA derivation for transaction building
“Before I submit my Solana transaction, I need to derive the PDA for program 'ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJe8bXh' with seed 'associated-token-account' — give me the address and bump.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/solana_pda_derive/invokeWhen to prefer
Use this endpoint when you need to deterministically compute a Solana PDA address and bump seed off-chain, without making an RPC call to a Solana node. Ideal for transaction construction, address pre-computation, or verification in agent workflows where you need the PDA before submitting a transaction. Prefer this over running findProgramAddressSync locally when your agent environment lacks a Solana SDK.
Side effects
- Invalid program ID format causes derivation failure
- Seeds that produce no valid off-curve point result in an error
- Malformed request_json (not valid JSON or missing required fields) returns a parsing error
- Seeds exceeding Solana's size limits cause an invalid input error
- Non-existent or incorrect program IDs silently derive an address without on-chain validation (warned in response)
