Common ways teams use Paywall to charge AI agents and crawlers per call — pick the one closest to your setup.
Charge AI agents per API call instead of provisioning keys and plans for callers you’ll never meet. Register a route, add one middleware, and any endpoint returns a signed x402 challenge — agents pay in USDC and the call succeeds.
Stop giving content to AI crawlers for free. Connect Cloudflare and a Worker decides allow, block, or charge at the edge — crawlers get a USDC price instead of free content, while human visitors pass through untouched.
Charge per tool call on your MCP server. Pair MCP with x402: each tool exposes a price, the agent’s runtime pays in USDC, and you settle per invocation — without building a billing system or handling wallets yourself.
Put a price on each query to a data or retrieval endpoint. Agents calling your search, embeddings, or RAG API pay per request in USDC — so high-value data earns per use instead of being scraped for free.
