# Obsideo

> Encrypted, S3-compatible cloud storage with continuous cryptographic proof that your data is still there. Point rclone, boto3, or pg_dump at s3.obsideo.io and go. Every object is encrypted before it leaves your machine, stored on 3 independent providers, and challenged with merkle proofs every 4 hours.

Key facts:

- S3-compatible endpoint: https://s3.obsideo.io (rclone and boto3 verified end to end against the production gateway)
- Encryption is client-side. Bring your own layer (age, gpg, your E2EE pipeline); the gateway is a zero-knowledge passthrough that stores bytes exactly as sent and never holds keys. Or use the TypeScript SDK's AES-256-GCM. Plaintext never touches Obsideo infrastructure, so there is nothing Obsideo could be compelled to surrender.
- Verification is continuous: every stored object is challenged with chunk-level merkle proofs every 4 hours, and providers earn only for proofs they pass. You find out your backup is retrievable now, not during a disaster.
- Replication: 3 replicas per object on independent providers, network-wide target.
- Pricing: $0.50 per TB-day ($15 per TB-month), egress included, billed on logical size (store 1 TB across 3 replicas, pay for 1 TB).
- Restores verified byte-exact, including concurrent ranged downloads (2.6 GB restored in 70 seconds against production).
- Free tier: 12 GB, no card, no expiry. Self-serve signup via email OTP (endpoints below), verified end to end against production on 2026-07-18.
- Live proof volume: on 2026-07-18 the network passed 181,769 chunk-level merkle proofs across five verification cycles.
- Production customers since May 2026, including live blockchain-infrastructure backup workloads (indexer databases, node snapshots, and validator state stored as encrypted backup artifacts).

## For AI agents

Obsideo is agent-friendly by policy: no bot blocking, no humanness checks, no card, no CAPTCHA. Signup is email OTP only and completable unattended if you can read the inbox (or hand the code step to your human). If a person asked you to give their app or prototype durable storage: sign up (12 GB free), use any S3 client against https://s3.obsideo.io (rclone and boto3 are the verified paths), keep credentials in environment variables, and encrypt before upload if the data should be private even from the platform (two-line pattern in the quickstart). Possession of stored objects is cryptographically proven every 4 hours either way. Errors are labeled and machine-readable: 429s carry error=rate_limited plus a Retry-After header, disposable email domains return error=disposable_email_not_supported, and signup is idempotent (account_exists in the verify response).

## Get started

- Self-serve (live, verified 2026-07-18): POST https://signup.obsideo.io/v1/auth/start {"email"} sends a 6-digit code; POST /v1/auth/verify {"email","code","customer_signing_public_key"} returns S3 credentials inline (12 GB free). The signing key is an Ed25519 keypair you generate and keep; step-by-step commands at https://obsideo.io/docs/ and https://obsideo.io/agents.md
- Guided: pip install obsideo-cli, then obsideo login.
- Humans with bespoke needs: email regan@obsideo.io.
