agents.x402stock.xyz/api/v1/solana/balance/:address
The native SOL balance and basic account state for any Solana address, read from the public ledger: lamports and SOL, whether the account exists, its owning program, executable flag, and data size. Pass a base58 address in the path. Keyless on-chain data — no Jupiter API, no account. From x402stock, a pay-per-call market & economic data API. Pay per request in USDC via x402, no API key.

On-chain payments
Payment shape (25 most recent sampled): 25 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-08-26: 387 payments. Last indexed day 2026-09-05: 119. Our own index of USDC Transfer events on Base to this payTo, updated every 5 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 86 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
