# Solana SPL Token On-Chain Mint Info

> Solana SPL Token On-Chain Mint Info is a paid API for AI agents from agents.x402stock.xyz, paid per call via MPP, $0.01/call, status unknown (last checked 2026-09-12).

Returns on-chain facts for a Solana SPL token mint: total supply, decimals, mint/freeze authority, initialization status, and token program type.

## 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 agents-x402stock-xyz-solana-spl-token-on-chain-mint-info-ce00c1c8
```

Example prompt: What's the total supply and mint authority for the BONK token on Solana? Pull the data straight from the on-chain ledger.

## When to prefer this

Use this endpoint when you need authoritative, real-time on-chain token supply and mint metadata directly from the Solana ledger, not from a third-party index like Jupiter. Ideal for due diligence on token minting rights, checking token standards (SPL vs Token-2022), or verifying supply figures without trusting aggregator caches.

## Known failure modes

- Invalid or malformed base58 mint address returns an error
- Unrecognized symbol that is not in the known mapping returns an error
- Token mint not found on Solana ledger returns not-found error
- Network or RPC connectivity issues may cause timeouts
- Token with very large supply may have supply_raw as a large integer string requiring careful parsing

## How this service works

On-chain facts for any Solana SPL token, read straight from the public ledger (not the Jupiter API): total supply and decimals, mint and freeze authority, initialization, and token program (SPL Token or Token-2022). Pass a base58 mint address or a known symbol (SOL, JUP, JLP, USDC, USDT, BONK, JTO, WIF). Keyless public-chain data, no account. From x402stock

## Output

A JSON object with the token's mint address, symbol (if mapped), decimals, total supply as a UI amount and as an exact raw integer string, mint authority, freeze authority (either a base58 address or null), whether the mint is initialized, the owning token program address, and the token standard ('spl-token', 'token-2022', or 'unknown'). Also includes source, venue, and an as_of timestamp.
