Monetize your API with x402 crypto payments. Keep 97.5% of every transaction. Get instant payouts in USDC. Reach both human developers and autonomous AI agents.
We take a 2.5% facilitator fee on x402 transactions. That's it. No hidden platform fees, no marketing charges, no "premium listing" upsells. Compare that to RapidAPI's ~20% commission.
x402 payments go directly to your wallet. No waiting 30-60-90 days for payout processing. USDC arrives in your wallet the moment the transaction settles on-chain.
AI agents are the fastest-growing segment of API consumers. They can't sign up for accounts or enter credit cards. x402 lets them pay per-call autonomously — your API earns revenue from customers that can't use traditional marketplaces.
Built on x402 — the open payment protocol backed by Coinbase. Your API isn't locked into a proprietary marketplace. Agents and developers can discover and pay for your service using any x402-compatible client.
See who's calling your API, how often, and how much revenue it's generating. Real-time dashboards, not monthly reports delivered weeks late.
Your API automatically becomes available to AI assistants via our MCP server. Claude Desktop, Cursor, and Windsurf users can discover and use your API without any extra integration work.
Here's what the math looks like on a $100 in gross revenue:
| Metric | RapidAPI | Arch Tools |
|---|---|---|
| Platform Commission | ~20% ($20.00) | 2.5% ($2.50) |
| You Receive | ~$80.00 | $97.50 |
| Payout Speed | Monthly (delays reported) | Instant (on-chain settlement) |
| Payout Currency | USD (PayPal/wire transfer) | USDC (or USD via standard billing) |
| Pricing Control | Tiered (Free/Pro/Ultra/Mega) | You set per-call price directly |
| Customer Types | Human developers only | Human developers + AI agents |
| Customer Relationship | Platform owns billing relationship | Direct — x402 payments go to your wallet |
| Marketplace Quality | Competing with 40K+ APIs (many abandoned) | Curated directory — quality over quantity |
Arch Tools acts as an x402 facilitator — we handle payment verification, routing, and settlement so you don't have to run blockchain infrastructure yourself.
Tell us about your API — what it does, your desired per-call price, and your USDC wallet address for payouts. We review submissions for quality and relevance.
We add your API to the Arch Tools directory with documentation, a live playground endpoint, and x402 payment configuration. Your API gets a dedicated URL at archtools.dev/v1/tools/your-tool-name.
Your API appears in our searchable directory, our MCP server (accessible to Claude Desktop, Cursor, Windsurf), and our x402 service discovery endpoint. Human developers browse the catalog. AI agents discover it programmatically.
When someone calls your API through Arch Tools, we route the request to your service, verify the x402 payment, take our 2.5% facilitator fee, and send the remaining 97.5% to your wallet. For credit-based calls (human developers with API keys), payouts happen on a regular billing cycle.
Monitor your API's usage, revenue, and performance through our analytics dashboard. See call volumes, error rates, response times, and revenue — in real time.
x402 is an open payment protocol backed by Coinbase. It works at the HTTP protocol level — payments are embedded in request headers, so your API can accept crypto payments without any custom integration.
// What happens when an AI agent calls your API on Arch Tools
// 1. Agent discovers your API's pricing
GET https://archtools.dev/.well-known/x402
// → Returns: accepted networks, assets, and per-tool pricing
// 2. Agent constructs payment and calls your tool
POST https://archtools.dev/v1/tools/your-tool-name

// 3. Arch Tools verifies payment, routes to your API, returns result
// 4. $0.00975 (97.5%) settles to your wallet
// 5. $0.00025 (2.5%) is our facilitator feeWe curate our directory for quality. Not every API gets listed — that's intentional. Here's what makes a strong submission:
We're not looking for thousands of APIs. We're looking for APIs that work, are maintained, and provide real value. Quality over quantity — always.
We're building a self-service provider dashboard where you can:
Until the dashboard is ready, submissions are handled personally. Email us your API details and we'll get you set up within 48 hours.
No. Arch Tools handles all x402 payment verification and settlement. You provide a standard REST API endpoint — we handle the crypto layer. All you need is a USDC wallet address (MetaMask, Coinbase Wallet, etc.) to receive payouts.
Yes. There's no exclusivity requirement. List on RapidAPI, AWS Marketplace, your own website, and Arch Tools simultaneously. We don't lock you in.
We support free tools too. If you want your API in our directory for visibility but don't want to charge, that's fine. No facilitator fee on free calls.
You choose your per-call price. We don't dictate pricing tiers or force "Free/Pro/Ultra" structures. If your API costs $0.05 per call, that's what users pay. We take 2.5% ($0.00125) and you receive 97.5% ($0.04875).
Any wallet that can receive USDC on Base (or the chain you prefer). MetaMask, Coinbase Wallet, Rainbow, or any EVM-compatible wallet works. For Solana-based payouts, any Solana wallet works.
You could run your own x402 facilitator — Arch Tools is open source, so you have that option. Listing with us adds: marketplace discovery, MCP server inclusion (your API appears in Claude/Cursor), our developer community, analytics, and payment handling. We earn our 2.5% by driving traffic and handling infrastructure.
Submit your API details via email. We review for reliability, documentation quality, and relevance. If accepted, we'll work with you to integrate it into the directory. Typical turnaround: 48 hours from submission to live listing.
Yes. Arch Tools is MIT licensed. You can review the facilitator code, the directory, and the payment handling. Transparency is core to how we build trust with providers.
