How this service works
OpenAI-compatible AI and data API for agents. Pay per call in USDC on Base via x402 — no API keys, no subscriptions, no lock-in.
Output
Returns a JSON object containing the queried Solana wallet address, its current SOL balance as a numeric string (e.g. '1.5'), and the network identifier ('solana').
Example use cases
Pre-transfer wallet verification
“Before I send SOL, check the balance on the sender wallet address 7dFp2...Qr9w and tell me how much SOL is available.”
DeFi agent portfolio tracking
“Fetch the current SOL balance for my Solana address 3mTn8...Vk1x so I can see if my holdings have changed since yesterday.”
Automated funding check for bot wallet
“Check whether the Solana wallet 5aHj6...Lp4c has enough SOL — I need to confirm it's funded before the agent can proceed.”

Endpoint
GEThttps://api.cortexcloud.org/x402/v1/data/solana/balanceWhen to prefer
Choose this endpoint when you need a lightweight, no-subscription, pay-per-call SOL balance lookup for Solana mainnet. It is ideal for AI agents that already support x402 micropayment flows on Base and want to avoid managing API keys or monthly plans. Prefer alternatives if you need batch balance queries, token balances beyond native SOL, or historical balance data.
Side effects
- Invalid or malformed Solana address returns an error response
- Payment failure via x402 if USDC balance is insufficient blocks the request
- Network or RPC unavailability may cause timeouts or empty responses
- Address with zero balance returns balance of '0' which may be misinterpreted as an error
