What sets it apart

Not a list of promises: each point comes with how to check it right now, without an account. If any of it ever stops being true, this page fails before you do.

1. The court file, already written

   A PDF with the applicable legal framework, what each piece of evidence proves, and the protocol for the opposing expert to check it without going through us. Limits included: a report that only says what suits it does not hold up before a judge.

   Check it → art. 326.2 LEC

2. The proof outlives us

   The fingerprint is on the Bitcoin chain. If CODEX shuts down tomorrow, your document is still verifiable with public tools.

   Check it → ots verify

3. Anyone can check without an account, any proof

   No signup, no cost, no permission. And not just ours: upload anyone's OpenTimestamps proof and we tell you what it anchors and where.

   Check it → POST /api/v1/verify/ots

4. Your AI can verify it

   Open MCP server. Claude or ChatGPT check a document with no work on your side.

5. You seal from your phone in seconds

   On Android, once installed, CODEX shows up in the Share menu: a PDF, a photo, a screenshot, three seconds. On iPhone, from the browser.

   Check it → share_target

6. They send it to you, sealed

   Your link in your email signature. Whatever they send arrives sealed with name and time, no account on their side.

   Check it → /recibir/<your-account>

7. Your public track record, if you want it

   How many documents you've sealed and since when. Never titles or clients. Opt-in.

   Check it → /emisor/<your-account>

8. Credentials in the standard W3C data format

   Each credential reads as a W3C Verifiable Credential. Not yet signed by the issuer (what wallets require): the proof points to Bitcoin.

   Check it → /v/<fingerprint>/w3c.json

9. The specification is public

   How the seal is computed, anchored and verified. Implement it if you like.

   Check it → /estandar

10. Your client opens it in their language

    36 languages, detected from the browser. You do nothing.

    Check it → Accept-Language

11. Unlimited documents, free, nothing per person

    No document cap, no per-seat price: the two grievances the industry squeezes with. (The emails CODEX sends on your behalf do have a daily quota, against spam.)
