What is Arch Tools?
63 tools. One API. Built for agents.
Arch Tools is an API platform. You get one key, and behind it is a broad toolset your agent (or your code) can call with a single POST request. No infrastructure to run, no libraries to install, no APIs to sign up for separately.
🤖
For AI Agents
Give your agent an API key. It can call Arch Tools to scrape data, generate text, look up prices, send email, and pay autonomously in USDC via x402. No human needs to approve anything.
👨💻
For Developers
Stop rebuilding the same utilities in every project. Need to hash data? Validate a phone number? Extract text from a PDF? One POST request, credits deducted, done. No monthly fees - buy credits once, they never expire.
🔌
For MCP Clients
Using Claude Desktop, Cursor, or Windsurf? Add 6 lines to your config and Arch Tools appear natively - your client knows what each one does and can use them automatically. No API calls in your prompts.

How it works
Three steps to your first API call
Register with your email, add credits, start calling tools. No infrastructure. No setup. Just POST requests.
🔑
Step 01
Register & get your key
Sign up with your email. You instantly receive an API key and 25 free credits - 75 more on email verification, no credit card required to start.
⟠
Step 02
Pay with USDC or Stripe
Agents pay autonomously with USDC · Base & Polygon via x402 - no human card needed. Humans can use Stripe. Both rails, one platform.
⚡
Step 03
Call any tool via REST
Every tool is a single POST request. JSON in, JSON out. Built for machines - works great for humans too.
Quick Start

x402 Protocol · Base & Polygon
AI agents pay with USDC, USDT, or ETH. Automatically.
Arch supports the x402 payment protocol - built on Coinbase Base and Polygon, settled in USDC/USDT. Your agent discovers tools, sees the price in USDC, pays autonomously, and calls the endpoint. No human in the loop, no wallet setup, no credit card management.
- → Agent hits endpoint → receives HTTP 402 with price + wallet address
- → Agent pays in USDC on Base or Polygon (USDC or USDT) - settles in seconds
- → Endpoint unlocks, tool executes, result returned
- → No wallet setup on your side - the protocol handles everything
- → Fallback: Stripe credits always available if you prefer traditional billing

Grok uses OpenAI-compatible function calling. Pass Arch Tools as tools in your request - Grok will call them autonomously when needed.
# Python - Grok function calling with Arch Tools
from openai import OpenAI
import requests
client = OpenAI(api_key="xai-your-key", base_url="https://api.x.ai/v1")

Quick Start
Up and running in 3 steps.
Get your API key, make your first call, and integrate with your agent - all in under 5 minutes.
STEP 1 - GET YOUR KEY
STEP 2 - FIRST CALL
STEP 3 - USE IN AGENT
# Register - 25 instant credits, 75 more on email verify
$ curl -X POST https://archtools.dev/v1/agent/register \
-H "Content-Type: application/json" \
-d '{"email":"[email protected]"}'
# → returns your api_key
# Call any tool with x-api-key
$ curl -X POST https://archtools.dev/v1/tools/generate-hash \
-H "x-api-key: arch_your_key" \
-H "Content-Type: application/json" \
-d '{"text":"hello","algorithm":"sha256"}'
// JS agent fetch example
const res = await fetch(
"https://archtools.dev/v1/tools/web-scrape",
{ method: "POST",
headers: { "x-api-key": API_KEY,
"Content-Type": "application/json" },
body: JSON.stringify({ url: "https://example.com" }) }
);
const data = await res.json();
Every response includes credits_remaining so your agent always knows its balance. Failed calls (4xx) never cost credits.
Questions
Frequently asked
Everything you need to know before your first API call.
What happens when my credits run out?
+
Your API calls return a 402 Payment Required response with a credit count of 0. Your key stays active - just top up via Stripe or send USDC directly to unlock the endpoint. No service disruption, no account deletion. Your data and key are preserved.
Do credits expire?
+
No. One-time credit purchases never expire. Buy once, use whenever. Every other API platform we know of expires your credits monthly - we don't, and never will. Subscription plans auto-refill credits each month, but unused credits carry over and don't disappear.
Can my AI agent pay without a human in the loop?
+
Yes - that's the entire point of the x402 protocol. Your agent hits a tool endpoint, receives a 402 response with a USDC price and wallet address, signs the payment from its own wallet, and retries the request. The endpoint unlocks automatically. No human approves anything. No credit card required on the agent side. This is HTTP-native machine-to-machine payment.
What's the difference between paying with USDC vs Stripe?
+
Both pay for the same tools at the same prices. The difference is who's paying. Stripe is for humans - you buy a credit pack or subscribe with a credit card, credits are added to your account, and every tool call deducts from that balance. USDC via x402 is for AI agents - the agent pays directly per call, on-chain, in real time, with no pre-purchased balance needed. You can use both on the same account.
Which blockchain networks are supported for payment?
+
Payments settle in USDC on Base and Polygon. If your agent holds USDC on either, it can pay. No bridging, no wrapping - send natively.
Is there a free tier? What do I actually get?
+
Register with your email - no credit card needed - and you instantly receive 25 free credits — and 75 more when you verify your email (100 total, refreshed every month). That's enough for substantial testing across web, utility, and AI tools before spending a dollar. No time limit, no expiry, no upsell wall. Use it to test the platform thoroughly. When you're ready to scale, one-time credit packs start at $9.
What exactly is a credit?
+
A credit is the unit of usage on Arch Tools. Each successful API call deducts credits from your balance - most utility tools (hash, UUID, validate) cost 1 credit. Mid-tier tools (web scrape, currency convert) cost 2-5 credits. AI generation and advanced tools cost 10-30 credits. Failed requests (4xx errors) are always free. Your current balance is returned in every API response as credits_remaining.
What is x402 and how does it work?
+
x402 is an open HTTP payment protocol - an extension of the classic 402 Payment Required status code. When an AI agent calls a tool without a pre-purchased balance, the server responds with a 402 containing a USDC price and wallet address. The agent signs a payment on-chain (Base or Polygon), includes the signed receipt in a retry request, and the endpoint unlocks immediately - all without a human or credit card. Arch Tools is the first production API platform to implement x402 natively. Learn more at x402.org.
How do I get an API key?
+
Register with just your email address - no credit card, no waiting. Visit archtools.dev/signup or POST to /v1/agent/register with {"email":"[email protected]"}. Your API key and starter credits are returned instantly in the response and displayed on screen; confirm the verification email to unlock the rest of your free credits. Store it safely - it's the only authentication you need across Arch Tools.
