# QuickBuild Solana Token Mint Info

> QuickBuild Solana Token Mint Info is a paid API for AI agents from quickbuild.quynguyenbac.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-02).

Fetches live SPL token mint metadata from Solana mainnet RPC for a given mint address, including supply, decimals, and authority status.

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 quickbuild-solana-token-mint-info-2e377123
```

Example prompt: Can you look up the live on-chain details for the Solana token with mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — specifically whether the mint and freeze authorities have been revoked, the total supply, and the number of decimals?

## When to prefer this

Use this endpoint when you need live, on-chain SPL token mint metadata directly from Solana mainnet without running your own RPC node. Ideal for verifying token safety (revoked authorities), checking supply and decimals for DeFi calculations, or enriching token data in an agent workflow. Prefer this over general blockchain explorers when you need structured, machine-readable JSON responses with explicit null handling and no invented data.

## Known failure modes

- 404 Not Found — address exists on Solana but is not an SPL mint account
- 400 Bad Request — mint address is malformed or not valid base58
- RPC timeout or Solana mainnet congestion causing delayed or failed response
- Null fields in response when on-chain data is missing or not applicable

## How this service works

Mint account read live from the public Solana mainnet RPC (jsonParsed). Every response has disclaimer: "informational only, not investment advice"; unavailable values are null (never invented). Not a mint = 404, invalid = 400, never charged.

## Output

Returns a JSON object with the token's on-chain supply (as an object), decimals (integer), token program identifier, boolean flags for whether mint authority and freeze authority are revoked, and a disclaimer string. Unavailable fields are returned as null rather than invented values. Returns 404 if the address is not a mint, 400 if the address is invalid.
