Frequently asked questions
Each dataset is assigned a unique digital fingerprint (CID) at upload, creating a verifiable record of its contents. The system then automatically checks your data on a recurring basis (about every 24 hours) to confirm that the data still matches that original fingerprint, ensuring nothing has been altered.
Fil One provides an S3-compatible API: if your application works with AWS S3, it works with Fil One. Point your SDK or CLI at our endpoint and authenticate with your API keys.
Fil One takes a security-first approach to S3-compatibility. The S3-compatible API enables simple setup and migration. Storage supports private buckets by default, with public access consistent with full S3 parity coming soon.
Read Fil One docs, access the app to get started with no code required, or talk to someone on our team to get started.
Fil One is optimized for large-scale storage needs, including AI and data-intensive workloads, multi-cloud strategies, audit-sensitive data, and long-term retention.
Fil One uses industry-standard encryption with per-object data encryption keys, ensuring your data is protected regardless of which provider it's stored with. We are actively pursuing SOC 2 Type II and ISO 27001 certifications — if you'd like to be notified when those are finalized or have other questions about security, reach out to our team directly at security@fil.one.
After you create an account and provision your first bucket, migrating to Fil One is straightforward with our S3-compatible interface. You can integrate directly into your codebase using any S3-compatible SDK, or use the AWS CLI to migrate your data with a single command.
For enterprise teams who want more hands-on support during migration, our team is available to walk you through every step. Reach out at sales@fil.one, and we'll make sure the transition is seamless.
Bucket Intelligence turns your Fil One buckets into queryable knowledge bases. Powered by a built-in RAG Pipeline, files are auto-indexed as they land in your bucket. You can ask questions in plain language and get answers grounded in your actual data.
You bring your own LLM API keys (OpenAI, Anthropic, or Cohere), so AI costs go directly to your provider. Bucket Intelligence is free for early testers.
The AI Agent Toolkit lets you connect your AI tools and automations to Fil One. Pick an integration, paste a config block, and your buckets are immediately available for your AI agents to use or to trigger automations from bucket events.
It works with your existing buckets, no new setup or credentials needed. Access can be revoked at any time. Free for early testers.
No. Object Storage is the foundation every Fil One account starts with, and it works great on its own as a fully S3-compatible store. Bucket Intelligence and AI Agent Toolkit are coming soon and will connect directly to your existing buckets with no data migration needed.
Filecoin is a distributed storage network launched in 2020, designed to make data portable, verifiable, and resilient by default.
Instead of relying on a single proprietary vendor, Filecoin uses open protocols and an open market to store data with a global network of independent providers — helping reduce single points of failure and deliver true multi-cloud durability.
One network. One record. One less thing to worry about.
