## Pages

Requests by email to contact@noxfze.com, subject "Venue record request (agent)".

- [Venues](https://noxfze.com/venues): An independent, verifiable record of a venue's public market data: a recorder dedicated to the venue seals each UTC hour into a hash-chained record that anyone the venue shares it with can check with openly available tools, delivered into storage the venue owns within 15 minutes after the hour closes unless that storage or the recorder is unavailable. Perpetual and spot instruments; a 30-day pilot at no fee, then a monthly fee under a written order form; requests by email to contact@noxfze.com. A venue can share any hour of its public market data, as Nox recorded it, with a partner, a data aggregator or a researcher, who can check that hour against its hashes.
- [Verification](https://noxfze.com/verify): verify a sealed hour in the browser; every hash of the hour and its link to the hour before are recomputed, and no file leaves the browser
- [Documentation](https://noxfze.com/docs): Nox FZE, an independent company, records your venue's public market data. Each UTC hour becomes a sealed hour in a hash chain, delivered into storage you own within 15 minutes after the hour closes. If your storage or the recorder is unavailable, the hour arrives later. Anyone you share a sealed hour with can recompute its file hashes and its link to the hour before with openly available tools. Markdown: https://noxfze.com/docs.md
- [Record format, version 1](https://noxfze.com/docs/format): Record format version 1 is the contract of every sealed hour. It states where the files of a sealed hour sit in storage you own, and how time, JSON and hashes are encoded. It defines the raw file, the normalized tables, and the hourly and daily manifests that form the hash chain. It lists the ten checks a verifier makes. Within version 1, only optional manifest fields and new columns may be added. Markdown: https://noxfze.com/docs/format.md
- [Command-line verification](https://noxfze.com/docs/verify): Three openly available tools verify a sealed hour against its manifest and against the hour before it. `jq` reads the manifest, `b3sum` recomputes BLAKE3 hashes, and `zstd` opens the raw file. The commands verify the format version, each listed file's size and hash, the raw file's line count, and the hash chain link to the previous hour. Each command prints its result and exits with a non-zero status when its check fails. Markdown: https://noxfze.com/docs/verify.md
- [Synthetic example hour](https://noxfze.com/docs/example): The synthetic example hour is one sealed hour and the hour before it, as one download, for the synthetic venue `example` and its channel `trades`. It holds no market data. It includes both daily manifests and the test key set that their signatures verify against. Markdown: https://noxfze.com/docs/example.md
- [Starting a record](https://noxfze.com/docs/start): A record starts with a written request and an order form that both sides sign. Each sealed hour is delivered into storage you own, through a write-only key you give Nox. The record opens with a 30-day pilot at no fee, then continues for a monthly fee set out in the order form. Nox works in writing, by email. Markdown: https://noxfze.com/docs/start.md
- [Questions venues ask](https://noxfze.com/docs/questions): Short answers to what a venue asks before a record starts: what is recorded, who holds it, how an hour is verified, its price and how it starts. Each answer links to the page that states it in full. Markdown: https://noxfze.com/docs/questions.md
- [Contact](https://noxfze.com/contact): Nox FZE works in writing. Send requests by email to contact@noxfze.com. Markdown: https://noxfze.com/contact.md
- [Home](https://noxfze.com/): the company in five chapters, from the hero through design, engineering and operations to contact
- [Legal notice](https://noxfze.com/legal): company details, registered office and the address on the license, license and licensed activity, services, official channels, governing law, disclaimers, accessibility and security
