# VerticalAPI

> Independent LLM API intelligence. VerticalAPI helps developers and technical
> buyers choose a model or provider using current, source-checked pricing,
> capability, lifecycle and benchmark evidence. Built by Brandyze in
> Aix-en-Provence, France.

## Direct answer

VerticalAPI is primarily a public decision layer for LLM APIs, not a model host
and not a token reseller. Its connected corpus contains model/API pages,
provider profiles, decision comparisons and benchmark research. Facts that can
change carry a verification date and relevant pricing or access conditions.

Current repository inventory, verified 2026-08-23:

- 50 model and API pages
- 61 comparison pages
- 25 provider profiles
- 173 sitemap URLs

These are coverage counts, not customer, traffic or adoption metrics.

## Primary research routes

- [Model and API directory](https://verticalapi.com/apis/) — current model IDs,
  pricing, context, lifecycle and direct provider access where published
- [Provider profiles](https://verticalapi.com/verticals/) — API platform facts,
  access routes and operational context
- [LLM comparisons](https://verticalapi.com/vs/) — 61 decision pages organized
  around providers, workloads, cost, context and capabilities
- [Benchmark](https://verticalapi.com/benchmark/) — latency, throughput, list
  cost and heuristic quality data with methodology and limitations
- [Guides and research](https://verticalapi.com/resources/)

## Evidence policy

VerticalAPI uses this source hierarchy:

1. First-party provider documentation and pricing pages.
2. First-party provider announcements and changelogs.
3. Reproducible VerticalAPI measurements with method and limitations.
4. Secondary sources only when the primary source does not publish the fact,
   with the limitation stated.

Provider-published claims and VerticalAPI measurements are kept separate.
Unpublished or unavailable facts are labelled "not published" or left
incomplete; missing coverage is never represented as zero. Pricing statements
must include relevant context tiers, regions, preview status, temporary rates or
other conditions. See [methodology](https://verticalapi.com/about#methodology).

## Corrections and commercial independence

Providers and readers can submit a listing or factual correction at no charge
through the [structured request route](https://verticalapi.com/request/) with
the page URL, exact field and an official source.

Sponsored placements, if offered, are visibly labelled and cannot change factual
tables, methodology, editorial rankings or conclusions. Custom data research is
scoped separately. See [listings and data services](https://verticalapi.com/pricing)
and [correction policy](https://verticalapi.com/about#corrections).

## Secondary gateway utility

VerticalAPI also operates a beta OpenAI-compatible BYOK gateway at
`https://api.verticalapi.com/v1`. The gateway is a secondary developer utility,
not the primary product promise. It routes calls to upstream LLM providers and
does not host model weights. Access is handled directly while the public offer is
being aligned with the capabilities proven in code.
