# FluxA Monetize > Discovery gateway and payment layer for agents. Find external APIs, LLM models, and skills at one endpoint and pay per call over x402 (HTTP 402); the FluxA Wallet CLI settles payment so the agent never writes payment code. ## Start here - [Agent skill (fluxa-monetize)](https://monetize.fluxapay.xyz/skill.md): the self-updating skill file.
