# Solana SPL Mint Account Decoder

> Solana SPL Mint Account Decoder is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Decodes and analyzes a Solana SPL token mint account's raw data, returning parsed fields like decimals, supply, mint authority, and freeze authority.

## Facts

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-spl-mint-account-decoder-f21690ef -d '<json body>'
```

Example prompt: Decode this Solana SPL mint account data for me — I need to know the token's decimal places, total supply, mint authority, and whether freeze authority is set: {paste mint account JSON here}.

## When to prefer this

Use this endpoint when you have raw Solana SPL token mint account data and need to extract structured token metadata (decimals, supply, authorities) without making a live RPC call to the Solana network. Ideal for offline analysis, audit pipelines, or when you already have the account data cached and want cheap, fast decoding at $0.01 USDC per call.

## Known failure modes

- Malformed or invalid JSON input results in a parsing error
- Incorrect token program identification leads to misinterpreted fields (warning issued)
- Missing required mint account fields cause incomplete or null output values
- Supplying non-mint account data returns incorrect decoded values without error
- Network mismatch if non-Solana data is supplied

## Output

Returns a parsed JSON object containing: decimals (token decimal places), display_supply (human-readable supply), supply_atomic (raw supply integer), mint_authority (public key or null), freeze_authority (public key or null), is_initialized (boolean), and the analyzed_network identifier. Also includes any warnings about caller-supplied data accuracy, plus a receipt with payment and execution metadata.
