# How KeepRouter researches and maintains its editorial library

> KeepRouter's library is engineering guidance rather than an anonymous ranking site. Product facts are tied to named sources and review dates; changing prices, catalogs, limits, and policies remain subject to the linked first-party records. We do not present vendor documentation as hands-on test evidence or invent customer results.

## Editorial team

KeepRouter Editorial maintains the public guides with review from the engineers who operate the product. The team covers multi-model API contracts, migration, routing, billing evidence, reliability boundaries, and developer tooling. The byline identifies a maintained editorial function, not a fictional individual author.

## Source standard

For product capabilities, limits, pricing rules, policies, and migration contracts, we prefer the vendor's current documentation, API reference, pricing page, release notes, or other first-party record. A comparison page names the sources it used and the date that source set was opened and reviewed. Readers should recheck volatile facts before a purchase or production change.

Third-party analysis may provide context, but it does not replace a primary source for a vendor claim. KeepRouter-owned routes such as the live model catalog, OpenAPI document, security page, and legal pages are the authority for KeepRouter's current public contract.

## What our evidence can prove

Documentation proves what a vendor publishes. A configured request proves only what that exact route, model, payload, region, and time window returned. A usage record and an invoice each describe their own accounting layer. We keep those boundaries explicit and do not turn one sample into a universal speed, cost, reliability, or quality claim.

We label shortlists as unranked unless a reproducible method and result set support an order. We do not publish synthetic benchmark scores, undisclosed paid placements, invented hands-on testing, customer logos, testimonials, or case studies.

## Review and correction process

An updated date changes only when the page's substance or source review changes. Comparison sources carry a separate reviewed date so a copy edit cannot silently refresh product evidence. When a material error is found, we correct the page, update the relevant date, and narrow or remove the unsupported conclusion. Corrections can be reported through the contact channel on the site.

## AI-assisted work

AI tools may help organize notes, inspect structure, or draft alternatives. A human-owned editorial pass remains responsible for source selection, claim boundaries, links, dates, and final publication. AI output is not treated as a source, test result, or customer evidence.

## Commercial boundary

KeepRouter's editorial library explains a product sold by KeepRouter, so it is not independent journalism. Comparisons state where KeepRouter fits and where it does not. Product inclusion is not an endorsement, and a link does not establish partnership, integration, or feature parity. Current service terms, model availability, and customer prices remain on their designated product and legal pages.
