Path 1 — MCP address no form, ever recommended

Point any MCP-compatible client at one URL. The first tool call auto-issues an ak_live_... key behind the scenes — there is no dashboard signup, no email, no approval queue.

{
  "mcpServers": {
    "apibase": {
      "url": "https://apibase.pro/mcp",
      "transport": "streamable-http"
    }
  }
}

Works in Claude Desktop, Claude Code, Cursor, Windsurf, ChatGPT, OpenAI Agents SDK, LangChain, Google ADK, CrewAI — full per-framework config on /frameworks.

Path 2 — REST + API key one throwaway POST

Get a key with a single unauthenticated request — no name, no email, no plan selection:

curl -X POST https://apibase.pro/api/v1/agents/auto
→ {"agent_id":"...", "api_key":"ak_live_...", "tier":"free"}

Use it on any call:

curl https://apibase.pro/api/v1/tools/crypto.get_price/call \
  -H "Authorization: Bearer ak_live_..." \
  -H "Content-Type: application/json" \
  -d '{"params": {"coins": ["bitcoin"]}}'

Free tools respond immediately. A priced tool without a payment header replies HTTP 402 with a challenge — sign it with either rail below and retry.

Path 3 — bare wallet, zero registration MPP / Tempo

No key, no /agents/auto call, no prior request of any kind. Sign an MPP payment against a Tempo wallet (set up once at wallet.tempo.xyz, via the mppx SDK) and send it as your very first request — the payment itself creates your agent identity, deterministically, from the wallet address:

npm i mppx

import { pay } from "mppx";

const res = await pay("https://apibase.pro/api/v1/tools/crypto.get_price/call", {
  network: "tempo",
  params: { coins: ["bitcoin"] },
});

No prior call ever touched apibase.pro from this wallet — the first payment IS the signup.

x402 on Base now bootstraps identity from the wallet alone too (as of 2026-09-02) — a signed x402 payment with no prior API key auto-registers your agent exactly like MPP, deterministically keyed to your wallet address. The example above uses MPP because mppx handles the signing for you; the same “first payment is the signup” guarantee now holds for x402/Base too.
