Give your agent one API key. It can instantly scrape the web, generate text with Claude, GPT-4, Grok, or Gemini, convert files, detect PII, look up crypto prices, send email, transcribe audio, and more - and pay autonomously in USDC across 15 blockchains. No credit card needed.
Arch Tools is an API platform. You get one key, and behind it are 64 ready-to-use tools 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.
Give your agent an API key. It can call any of the 64 tools to complete tasks - scrape data, generate text, look up prices, send email - and pay autonomously in USDC via x402. No human needs to approve anything.

Every tool is a single POST request. JSON in, JSON out. Built for machines - works great for humans too. Scraping that handles JavaScript, AI that routes to any model, voice in and out, real-time memory, SMS, email, payments, legal.
5 crypto tools powered by CoinGecko - live prices, market caps, news, historical data, and token lookup. Your trading agent or portfolio tracker gets real-time market data in one API call.

Arch supports the x402 payment protocol - built on Coinbase Base, Ethereum, Arbitrum, Polygon, Optimism, and Solana. 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.
Arch ships a native MCP server. Pick your client below - copy the config, paste it in, and all 64 tools appear natively. Works on Mac, Windows, and Linux.
Config file: Mac: ~/Library/Application Support/Claude/claude_desktop_config.json | Win: %APPDATA%\Claude\claude_desktop_config.json | Linux: ~/.config/Claude/claude_desktop_config.json
Arch Tools plugs into the tools you already use. SDKs, framework adapters, and MCP support — ready to go.
Buy once, use whenever. Credits never expire. Or subscribe monthly and auto-refill. You choose.
Limits are per API key. x402 micropayment calls bypass rate limits entirely - the chain is the ratelimiter.
| Plan | Requests / min | Requests / hour | Concurrent | Timeout |
|---|---|---|---|---|
| Free | 20 | 200 | 5 | 30s |
| Developer · $19 | 60 | 1,000 | 15 | 30s |
| Pro · $49 | 200 | 5,000 | 50 | 60s |
| Business · $149 | 600 | 20,000 | 100 | 120s |
429 responses include a Retry-After header. x402 per-call payments have no rate limit. Need higher limits? Contact us.
5,000 credits, never expire. Here's what that looks like in practice - pick any tool, run it, repeat until empty.
Mix and match across all 64 tools. Credits never expire - use them at your own pace.
Credits are consumed per successful API call. Failed calls (4xx errors) never cost credits. Here's what each tool category costs.
| Tool Category | Examples | Credits / call | Calls per $9 |
|---|---|---|---|
| Utility | UUID, hash, QR code, regex, readability | 1 | 10,000 |
| Validation | Email verify, phone validate, PII detect | 2 | 5,000 |
| Conversion & Data | Currency, format convert, JSONPath, language detect | 3-5 | 2,000-3,333 |
| Crypto & Finance | Crypto price, OHLCV, fear/greed, sentiment | 5-10 | 1,000-2,000 |
| Web & Search | Web scrape, search, RSS parse, screenshot | 5-10 | 1,000-2,000 |
| AI Generation | AI text, image generate, OCR, browser task | 10-30 | 400-1,000 |
Every API response includes credits_used and credits_remaining so your agent always knows its balance. Failed calls (4xx) are always free.
Every competitor charges per tool, per call, or per seat. You get 64 tools, 15 payment networks, and MCP support from $9. No other platform comes close.
| Platform | Entry Price | Tools Included | x402 / USDC | MCP Native | Agent Auto-Pay |
|---|---|---|---|---|---|
| ⚡ Arch Tools | $9 / $19/mo | 64 tools | ✓ Native | ✓ Yes | ✓ Yes |
| AbstractAPI | $20/tool | 1 per plan | ✗ | ✗ | ✗ |

AbstractAPI: 64 tools × $20/tool = $1,280/mo vs Arch Tools $9 one-time or $19/mo. That's 67× cheaper at entry tier.
Register in 10 seconds. 100 free credits, no card required. Your agent can be calling tools in under a minute.
Get your API key, make your first call, and integrate with your agent - all in under 5 minutes.
Every response includes credits_remaining so your agent always knows its balance. Failed calls (4xx) never cost credits.
Everything you need to know before your first API call.
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.
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.
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.
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.
15 networks: Base, Ethereum, Arbitrum, Polygon, Optimism, Avalanche, Unichain, Monad (EVM/USDC), plus Solana, Noble/Cosmos, Algorand, Stellar, Sui, Polkadot, Aptos. USDT is accepted on 6 EVM chains. Native tokens supported: ETH, BNB, NEAR, SOL, TAO. If your agent holds any of these, it can pay. No bridging, no wrapping - send natively.
Register with your email - no credit card needed - and you instantly receive 100 free credits, refreshed every month. That's enough for ~20 web scrapes, ~50 hash/validate/UUID calls, or 5 AI generations. No time limit, no expiry, no upsell wall. Use it to test every tool before spending a dollar. When you're ready to scale, one-time credit packs start at $9.
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.
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, Solana, or Ethereum), 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.
Register with just your email address - no credit card, no verification email, no waiting. Visit archtools.dev/signup or POST to /v1/agent/register with {"email":"[email protected]"}. Your API key is returned instantly in the response and displayed on screen. Store it safely - it's the only authentication you need for all 64 tools.
