## Koios News: an AI-assisted newsroom with RSS feeds and a $0.25 x402 briefing

**[Koios.News](https://koios.news/) is a general news publication of the 561 Group, subtitled "General news with systems-analysis depth", that discloses how it is made: source-bound AI research and drafting, recorded newsroom desks, independent editorial assessment, signed publication authority and dated public corrections.** It publishes in ten sections, offers RSS, Atom and JSON feeds, and sells a source-led intelligence briefing for $0.25 over x402, which a regular browser cannot buy and an x402-compatible client can.

Koios is one of the Group's public services that you do not need the Group's vocabulary to use: open the front page, read a story, and decide whether its evidence convinces you.

### What is Koios.News?

Koios.News reports general news: the front page on 2026-10-21 carried a boxing result, a documentary's box-office opening, a Bitcoin price move and sanctions and diplomacy stories, grouped by desk. Its tagline claims systems-analysis depth; the editorial standards state what that means in practice: report from named sources, link the underlying documents when available, distinguish what a source says from what the evidence establishes, identify analysis as analysis, and preserve material uncertainty or contrary evidence instead of smoothing it away.

The publication's sections are World, US Politics, Business & Markets, Crypto, Technology, Science & Climate, Health, Culture & Entertainment, Sport, and Opinion & Analysis. On 2026-10-21 the front page counted 66 reports across them, with Culture & Entertainment (22) and World (17) the largest.

### Is Koios written by AI? How does it disclose that?

Yes in part, and it says so. Koios.News "uses source-bound AI research and drafting, real recorded desk and reporter offices, independent editorial assessment, signed publication authority, and dated public corrections." Desk bylines (for example "Koios.News Culture & Entertainment Desk") identify coverage areas. A named specialist byline identifies an explicitly disclosed AI editorial character seated in a recorded newsroom office, "not a human journalist or a claim of first-hand interviews or observation." No writer can authorize publication merely by producing a draft. Software and AI agents may assist source research, drafting, independent editorial assessment, rendering and publication, but articles remain bound to cited source evidence, deterministic checks and independent acceptance, and "generated or automated assistance is never a substitute for attributable reporting."

Ownership and funding are on the [About page](https://koios.news/about/): Koios.News is owned and published by the 561 Group, which funds it; it also carries advertising and offers paid products, and those revenue paths do not buy editorial coverage.

### How does Koios handle sources, claims and corrections?

Three features set it apart from a typical news site.

- **Claim records.** The [claims](https://koios.news/claims/) index carries a record for assertions in the reporting, grouped by topic (economy, politics, technology, war, entertainment and others), with the guidance to read the record and its source before treating an assertion as fact.
- **The wire.** [The wire](https://koios.news/wire/) lists links to work published by named outlets, explicitly "not Koios reporting", each with a claim record, so a reader can tell aggregation from original reporting.
- **A corrections register.** [Corrections](https://koios.news/corrections/) are recorded on the affected article and in a public register with the date and what changed, plus a machine-readable JSON version. Entries as of 2026-10-21 include a headline corrected to name community banks as plaintiffs in a suit against the OCC over crypto trust bank charters, and a category and desk byline corrected on an article about Welsh devolution, with the original date and URL retained.

The [newsroom sources page](https://koios.news/sources/) lists the configured intake feeds (outlets such as the BBC, The Guardian, Al Jazeera, CNBC, CoinDesk, Cointelegraph, Decrypt, The Verge, Ars Technica and The Register) with the caveat that "listing a feed does not mean every item has been independently verified or published."

### How do I follow Koios without an algorithmic timeline?

Subscribe to a feed:

| Format | Address |
| --- | --- |
| RSS | [koios.news/feed.xml](https://koios.news/feed.xml) |
| Atom | [koios.news/feed.atom](https://koios.news/feed.atom) |
| JSON Feed | [koios.news/feed.json](https://koios.news/feed.json) |
| Sitemap | [koios.news/sitemap.xml](https://koios.news/sitemap.xml) |
| Archive | [koios.news/archive/](https://koios.news/archive/) |

As for cadence, we will be plain: Koios publishes in bursts, not on a fixed daily schedule. On 2026-10-21 the archive listed 76 posts for 2026 and 14 for 2025, and the JSON feed's recent items cluster around the days of 26 September, 2 to 6 October and 17 to 20 October 2026. The most recent publication date shown on the front page was 20 October 2026. If you need to know that something new has arrived, a feed reader is the right tool.

### What is the Koios Intelligence Briefing?

It is an x402-payable product: "the current Koios intelligence issue: bounded source-led analysis with every section linked to its cited evidence." It costs **$0.25** per call, in USDC on Base, at:

```
GET https://market.561.group/v1/koios/briefing/current
```

The response is JSON of kind `koios.news.intelligence-briefing/v1`, with an `id`, an `issuedAt` timestamp, a `title`, a non-empty list of `sections` (each with a heading, Markdown body and a list of source URLs) and a `references` object that maps each source URL to a bibliographic record. The catalog's example is a briefing id of the form `koios-intelligence-briefing:2026-09-24:2026-09-25`, a window of a day. The briefing is a recoverable offer: send an `X-Payment-Recovery` token generated before payment, and a dropped connection after payment returns the exact purchased response rather than charging again.

Koios.News itself says that "purchase requires an x402-compatible client; a regular browser cannot complete checkout", and links to the [payment terms](https://market.561.group/v1/koios/briefing/current). Opening that address in a browser or with `curl` returns `402 Payment Required` and a `payment-required` header, which you can read without paying. The step-by-step method is in [How to buy from an x402 market as a software agent](https://services.561.group/how-to-buy-from-an-x402-market-as-a-software-agent/).

### Why would anyone buy a briefing for a quarter?

Honestly, we do not know that anyone will; the market's own notes treat demand as unknown. The reasoning behind the product is the one that runs through [what we learned selling on x402](https://services.561.group/what-happens-when-you-sell-an-api-on-x402/): a machine buyer pays for what it needs mid-task and cannot get free, and a current, source-linked summary with machine-readable references fits that better than a horoscope does. An agent that needs "what is the situation today, and where is the evidence?" can buy one JSON document and cite its references. A person who wants the reporting itself can read the site for nothing.

### How does Koios relate to the rest of the Group?

Koios.News is one of the Group's public services; the Group's other doors are the [market](https://services.561.group/the-130-offer-x402-market-explained/) where the briefing is sold, the [bazaar and shop](https://services.561.group/market-bazaar-and-shop-explained/), the [games at Play](https://services.561.group/play-561-group-games-with-visible-odds/), and the [Turntide Islands](https://turntide.561.group/) climate-adaptation community. Its Crypto desk covers the same x402 and stablecoin territory the Group researches; the Group's own analysis of that market is in [How big is the x402 market?](https://services.561.group/how-big-is-the-x402-market/) and [What is x402?](https://services.561.group/what-is-x402/)
