## When to prefer this

Use this endpoint when you need a simple, pay-per-call lookup of a Solana wallet or program account balance without setting up API keys or subscriptions. Ideal for AI agents that need occasional on-chain Solana balance checks and are already operating within the x402 payment ecosystem on Base.

## Known failure modes

- Invalid or malformed Solana address returns an error or account not found response
- Account does not exist on-chain (exists: false in response)
- Payment failure via x402 if insufficient USDC balance on Base
- Network timeout or Solana RPC node unavailability
- Rate limiting or downstream RPC congestion causing slow response

## How this service works

Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.

## Output

Returns a JSON object with the SOL balance as a decimal, raw lamports, account owner program ID, whether the account exists, data size in bytes, whether it is executable, and a timestamp of when the data was retrieved, sourced from x402stock via Solana mainnet.
