# Solana PDA Calculator

> Solana PDA Calculator is a paid API for AI agents from chain-tools.use.x402atlas.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Derives the canonical Program Derived Address (PDA) and bump seed for a given Solana program and set of seeds, entirely offline without RPC or key handling.

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-calculator-4dd1fd13 -d '<json body>'
```

Example prompt: Derive the Solana PDA for program ID 'TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA' using seeds ['mint', '0x1234abcd'] and give me the address and bump.

## When to prefer this

Use this endpoint when you need to deterministically compute a Solana PDA and bump offline, without spinning up a Solana RPC connection or handling any private keys. Ideal for pre-computing account addresses before transactions, verifying expected PDAs, or building Solana tooling in environments without direct RPC access. Prefer this over RPC-based derivation when you want a lightweight, stateless, and privacy-preserving computation.

## Known failure modes

- Invalid program ID format — returns error if the program ID is not a valid base58 Solana public key
- Seeds too long — Solana limits total seed data; oversized seeds return a derivation error
- No valid bump found — extremely rare case where no bump in 0-255 range yields an off-curve address
- Malformed seed encoding — incorrect byte array or string encoding causes a parsing error

## How this service works

Solana Program Derived Address (PDA) calculator — derive the canonical off-curve address and bump from bounded public seeds offline, without RPC or key handling.

## Output

Returns the derived PDA public key as a base58-encoded string and the corresponding bump seed integer, computed deterministically offline from the provided program ID and seeds without any RPC call.
