# Solana Program API
> Inspect deployed Solana programs live from public Solana RPC — no key — and answer the question that matters most for safety: can this program still be changed, and by whom? For any program address it resolves the loader it runs under, whether it is executable, its on-chain ProgramData account, the upgrade authority (or that it has been made immutable / frozen), and the slot it was last deployed at. A batch endpoint audits up to twelve programs at once — perfect for checking the upgrade authority of every program a protocol depends on before you trust it — and a loaders endpoint documents Solana's program loaders. Distinct from balance, token and transaction APIs: this is the program and upgrade-authority layer that auditors, wallets and security tooling rely on to judge whether a Solana program is safe. Live from the chain; short cache only.

## Authentication
All requests require your oanor API key in the `x-oanor-key` header. Get one at https://www.oanor.com/developer/keys.

```bash
curl -H "x-oanor-key: oanor_live_…" "https://api.oanor.com/solanaprogram-api/..."
