Code examples

From intent to receipt in a few lines

import { GistClient } from '@gistplus/client';

const intent = client.createIntent({
  capability: 'gpt-4-inference',
  maxPricePerRequest: 0.01,
  token: 'USDC',
  sla: { maxLatencyMs: 2000 }
});

const offer = await client.negotiate(
  'https://api.provider.com',
  intent
);

// Returns:
// {
//   pricePerRequest: 0.008,  // 20% discount!
//   sla: { maxLatencyMs: 1500 },
//   signature: "..."  // Ed25519 signed
// }

const session = await client.createSession(offer, {
  depositAmount: 1.0  // 1 USDC
});

console.log(session.remainingBalance);  // 1.0 USDC
console.log(session.pricePerRequest);   // 0.008
// Can make 125 requests on one deposit!

const result = await client.executeRequest(
  session.sessionId,
  { prompt: 'Explain quantum computing' }
);

console.log(result.data);     // AI response
console.log(result.receipt);  // Cryptographic proof

import { verifyReceipt } from '@gistplus/core';

const receipt = result.receipt;
verifyReceipt(receipt); // Throws if invalid

if (receipt.slaVerification.met) {
  console.log('SLA met');
} else {
  console.log('Breached — refund:',
    receipt.slaVerification.refundAmount);
}

import { gistMiddleware } from '@gistplus/server';

app.use('/api/*', gistMiddleware({
  connection,
  wallet,
  endpoint: 'https://your-api.com',
  pricing: { basePrice: 0.01, token: 'USDC' },
  sla: { maxLatencyMs: 2000 }
}));

// Every /api/* route is now monetized.

app.post('/api/inference', async (req, res) => {
  const result = await runInference(req.body);

  // Middleware auto-signs the receipt
  return res.gistReceipt?.(result);

  // Receipt includes:
  // - Ed25519 signature
  // - SHA-256 input/output hashes
  // - SLA verification
});

import { LoadBasedPricingStrategy } from '@gistplus/server';

const pricing = new LoadBasedPricingStrategy(
  0.01,   // base price
  'USDC',
  () => getCurrentLoad()  // returns 0-1
);

// 0% load  -> $0.01
// 50% load -> $0.015
// 100% load -> $0.02

// Anchor a receipt to Solana
pub fn anchor_receipt(
    ctx: Context<AnchorReceipt>,
    receipt_id: String,
    session_id: String,
    input_hash: String,
    output_hash: String,
    sla_met: bool,
) -> Result<()> {
    let receipt = &mut ctx.accounts.receipt;
    receipt.receipt_id = receipt_id;
    receipt.session_id = session_id;
    receipt.sla_met = sla_met;
    Ok(())
}

// Get offers from multiple providers
const offers = await Promise.all(
  providers.map(p => client.negotiate(p, intent))
);

// Pick the cheapest
const best = offers.sort(
  (a, b) => a.pricePerRequest - b.pricePerRequest
)[0];

// Agent auto-routes to the best deal.
