## 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-token-supply-authority-info-6fd83626 -d '<json body>'
```

Example prompt: What's the total supply, decimal places, and mint authority for the Solana token with mint address DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263?

## When to prefer this

Use this endpoint when you need on-chain SPL token supply and authority data for a Solana mint address — particularly when verifying tokenomics, checking if mint or freeze authorities are renounced, or enriching token profiles with supply information. It is more specific and cheaper than full token profile endpoints when only supply/authority data is needed.

## Known failure modes

- Invalid or malformed mint address returns an error
- Mint address does not exist on Solana mainnet
- Network timeout if Solana RPC is congested
- Supply returned as floating point may have precision issues for very large supplies

## How this service works

Total supply of a Solana token with decimals, mint authority, freeze authority and token program.

## Output

Returns a JSON object with the mint address, token program ID, number of decimals, total supply as a number, mint authority (null if renounced), and freeze authority (null if not set).
