That's it. Claude can now make AI requests that pay automatically from your balance.

Send a prompt to Claude or GPT-4. Cost deducted automatically from wallet balance.

  max_tokens  (optional) — 1-4096, default 1024
  system      (optional) — system prompt for context

Check your current USDC/SOL balance on SolanaProx.

Input:
  wallet  (optional) — defaults to configured SOLANA_WALLET

Estimate request cost before making it.

Input:
  prompt      (required)
  model       (optional)
  max_tokens  (optional)

List all available models and pricing.

Cached responses receive a 50% discount.

Typical request costs:

• Short question/answer: ~$0.001–0.003
• Code review (500 lines): ~$0.01–0.03
• Long document analysis: ~$0.05–0.15

Pay only for what you use. No $20/month subscription burning while you sleep.

AI agents that pay for their own inference — no hardcoded API keys, no human in the loop.

// Agent pays autonomously on every request
const res = await fetch("https://solanaprox.com/v1/messages", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "X-Wallet-Address": process.env.SOLANA_WALLET,
  },
  body: JSON.stringify({
    model: "claude-sonnet-4-20250514",
    max_tokens: 1024,
    messages: [{ role: "user", content: prompt }],
  }),
});

Let your app's users pay for AI features directly from their Phantom wallet. No backend payment processing required.
