Quickstart — sell your API to agents

​

Option A — deploy the template (5 minutes, no existing API)

1. Deploy with Vercel — it clones templates/serve-vercel into your GitHub.
2. Set T2000_PAY_TO to your Sui address. No wallet? npm i -g @t2000/cli && t2 init && t2 fund.
3. Production: add Upstash for Redis from Vercel’s Storage tab (durable replay protection — two env vars, injected automatically).

​

Option B — wrap your existing API (~15 minutes)

npm install @t2000/serve

import { createServeFromEnv } from '@t2000/serve';
export const serve = createServeFromEnv(); // reads T2000_PAY_TO

import { z } from 'zod';
import { serve } from '@/lib/serve';

const input = z.object({ query: z.string().min(1) });

export const POST = serve
  .route({ path: 'search', description: 'Web search, paid per call' })
  .paid('0.02') // USDC
  .body(input, z.toJSONSchema(input))
  .handler(async ({ body }) => yourExistingLogic(body));

export const GET = serve.openapi(); // app/openapi.json/route.ts
export const GET = serve.llms();    // app/llms.txt/route.ts

# The 402 challenge (free):
curl -s -X POST localhost:3000/search -d '{}' | jq

# A real gasless mainnet payment (needs a funded wallet — t2 init):
t2 pay http://localhost:3000/search --data '{"query":"test"}' --max-price 0.05

t2 check https://your-api.example/search          # every gate, dry run
curl -X POST https://mpp.t2000.ai/api/catalog/submit \
  -H 'content-type: application/json' \
  -d '{"url":"https://your-api.example/search"}'

What you just shipped

• 402 → sign → settle — the buyer signs a gasless USDC payment; serve verifies it structurally, runs your handler, submits it on-chain, and attaches the X-PAYMENT-RESPONSE receipt.
• No keys, no gas on your server.
• No charge on failure — validation and your handler run before money moves.
• Replay protection — challenge-once + digest-once, durable with a KV.
• Discovery — /openapi.json (with x-payment-info pricing) + /llms.txt.
