Delegare – let AI agents pay safely (x402, AP2 – base/USDC and Stripe)
Scoped spending mandates solve the private key problem better than x402 or pre-funded wallets.

x402 middleware for REST APIs, but agent payments are still niche and early.
API providers wanting to monetize endpoints for agent access; AI agent builders needing payment integration
Stripe · MoonPay · Magic Link
CrowPay fixes that. We integrate x402 payment headers into your existing API and configure USDC settlement on Base. You go from zero to agent-accessible in days, not months.
How it works:
You have an existing API (Express, Next.js, Cloudflare Workers, any HTTP server) We add x402 payment capability — your endpoints return 402 with payment instructions, agents pay in USDC and get access USDC settles to your wallet on Base. You get a dashboard with real-time analytics on agent payment volume.
That's it. You don't have to learn how x402 works under the hood, run blockchain infra, or change your API architecture. Why this matters now: There are over 72,000 AI agents paying for services via x402, with $600M+ in annualized volume across 960+ live endpoints. Stripe just added x402 support. CoinGecko is charging agents $0.01/request. This is going from experiment to real money fast — and most API providers are leaving it on the table because the integration is still too annoying.
The agent-side story: We also handle wallet creation and spending budgets for agent builders. If you're building agents that need to pay for things, Crow lets you create a wallet, fund it, set spending limits, and let your agent loose. The agent gets a budget, and you don't wake up to a surprise $10k bill.
What I'd love to hear:
What's keeping you from adding agent payments today? Is it technical complexity, uncertainty about demand, or something else? Agent builders: how do you handle spending controls? Is "agent gets a wallet with a budget" the right abstraction?

Walkthrough mode turns code review into pair programming where the agent points at your screen.
They revive HTTP 402 so agents can automatically buy API calls — the repo ships PayingClient/WalletManager primitives, an @x402-kit/core package, five agent templates (web-scraper, image-gen, search, translation, code-review), a live demo and 93 tests. Smart infrastructure play with a clear demoable surface; the hard part will be UX and economics (wallet funding, gas/settlement, and convincing API operators to adopt x402 instead of existing billing).
Well-built middleware betting on an agent payment economy that doesn't exist yet.
