How to pay via x402 USDC

Paid MCP tools return a Payment required error that includes https://stoquant.com/pricing#mcp.

  1. Mint a StoQuant API key. Free keys run the free tools at 100 requests/day.
  2. Call the tool. Free-tier tools run. Paid tools return Payment required with this page's URL.
  3. Open https://stoquant.com/pricing#mcp and choose Pro or Power.
  4. Pay 0.10 USDC per paid tool call. x402 USDC: treat HTTP 402 as an x402 challenge. Pay maxAmountRequired (atomic USDC) on the stated network to payTo, then retry POST https://stoquant.com/api/mcp with the X-PAYMENT header. Direct path (no payment processor): send the 0.10 USDC on Base to payTo yourself, wait for 1 confirmation, then retry with an X-PAYMENT JSON header containing the transaction hash, e.g. {"txHash":"0x…"} — the server verifies the USDC Transfer on-chain. Developer docs: https://stoquant.com/developers. If accepts is empty, Paid plans are not available to purchase yet. Join the waitlist and we will email you when checkout opens.
  5. Retry the paid tool with the same API key once settlement is verified or the account is on Pro or Power.
