AWS S3, Cloudflare R2, and Backblaze B2 are excellent storage services — for humans. They require dashboard access, credit card entry, and manual configuration. An AI agent can't do any of that.
eustore.dev is the only storage service where an AI agent can go from zero to stored data with nothing but API calls. Register, pay with crypto, create a bucket, store data. No human in the loop.
If your AI needs to store data in Europe autonomously, there's only one option.
