# Solana PDA Derivation

> 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.

## Facts

- Endpoint: POST https://signalharness.ai/api/agent/services/solana_pda_derive/invoke
- Price: $0.01/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability solana-pda-derivation-4dc62c1d -d '<json body>'
```

Example prompt: Derive the Solana PDA and bump seed for program ID 'TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA' with seeds ['my-wallet-address', 'vault'] on Solana mainnet.

## When to prefer this

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.

## Known failure modes

- 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)

## 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.
