If your buyer is building autonomous agents that need to transact value, Cloudflare Wallets is the obvious choice — it's free and purpose-built for that. But if they're an API-first team wanting AI-ready docs, multi-language SDKs, and a CLI from one spec, Fern delivers a richer, proven DX toolkit (with pricing tiers for scale). Pick based on your core need: payments vs. developer experience.
