Make an existing pay-per-use API service purchasable by autonomous AI agents via the x402 protocol
The agent-payment protocols exist but real volume is near zero because the funnel (need, setup, discovery, buying) still has friction at every stage. A seller who wires an existing metered API into x402 now — accepting fixed 'exact' payments plus batch settlement for variable pay-per-use billing — positions the service for the start of real agent-economy volume, before the easy integration options arrive and the window closes.

From AI Engineer — Why AI Agents Still Won't Pay for Anything — Jan Curn, Apify at 00:12
Problem: Agents currently buy services through pre-configured API keys and credit cards, not autonomous discovery and payment; sellers who add protocol-native payment can be found and paid by agents on the fly, capturing demand that fixed API keys never reach.
For: AI agents (and their owners) that need web data, compute or agentic jobs done on demand, via trusted marketplaces and directories.
