## 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 saylor-innovations-solana-token-authority-decoder-bc3ddb0b
```

Example prompt: Can you decode the token authorities for the Solana mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v and tell me if the mint authority is still active or has been revoked?

## When to prefer this

Use this endpoint when you need a quick, low-cost lookup of Solana token authority metadata — particularly for security screening, rug pull risk assessment, or DeFi token audits — without running your own Solana RPC node or parsing raw on-chain data. Prefer this over generic blockchain explorers when you need structured, machine-readable authority data for automated agent workflows.

## Known failure modes

- Invalid or malformed Solana mint address returns an error response
- Token address not found on-chain returns empty or null result
- Network timeouts or Solana RPC unavailability may cause slow or failed responses
- Non-token program accounts passed as input may return unexpected results

## How this service works

Solana Token Authority Decoder. A procedure for producing a mint-specific Solana token authority report: resolving the exact mint and program (SPL Token vs Token-2022), decoding mint/freeze authorities, enumerating Token-2022 extensions (transfer hooks, permanent delegate, default account state, close authority), separating metadata/update authority from supply economics, and analyzing controller addresses (multisig/PDA/program) — without inferring safety from any single revoked authority.

## Output

Returns a JSON document containing decoded authority fields for the specified Solana token, including mint authority address (or null if revoked), freeze authority address (or null if revoked), and upgrade authority details, enabling assessment of token control and centralization risk.
