# Solana Wallet Preflight Oracle

> Solana Wallet Preflight Oracle is a paid API for AI agents from home.chrz.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Checks a Solana mainnet wallet's SOL and USDC balances and returns a readiness assessment indicating whether the agent can transact now and what action to take next.

## 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-wallet-preflight-oracle-2e6930e2 -d '<json body>'
```

Example prompt: Can you run a preflight check on my Solana mainnet wallet 3mVCM1cokCNGkhTSWZtu4PjqSSx7VqpJyS74bY91wDgk and tell me if it has enough SOL and USDC to transact right now, and what I should do if it doesn't?

## When to prefer this

Use this endpoint when an AI agent needs to verify its Solana wallet is funded and ready before attempting an on-chain payment or x402-paid API call. It is ideal as a preflight step in agentic payment workflows to avoid failed transactions due to insufficient SOL for fees or USDC for payments. Prefer this over general blockchain explorers when you need a structured, action-oriented readiness signal rather than raw chain data.

## Known failure modes

- Invalid or malformed Solana wallet address returns an error
- Network timeout querying Solana mainnet RPC
- Wallet address not found on mainnet returns zero balances
- Payment of 0.1 USDC via x402 protocol fails due to insufficient funds in calling wallet
- Rate limiting if called too frequently

## How this service works

x402-paid Solana mainnet wallet preflight oracle for agents.

## Output

Returns a JSON object containing the Solana wallet address, chain identifier, current SOL balance, current USDC balance, a boolean indicating whether the wallet can transact immediately, and a recommended action string (e.g. 'top_up_sol') guiding the agent on what to do next.
