Overview

What the API directory provides

The API directory is a machine-readable benchmark intelligence hub for APIs and machine-facing services. It combines verified synthetic measurements with catalog metadata so people and agents can compare reliability, latency, infrastructure, and operational signals.

  • Weekly verified benchmark snapshots
  • Normalized provider, category, and subject records
  • Latency, pass-rate, CASC, and infrastructure signals
  • Human pages plus JSON data surfaces for agents
Rankings

Top performing providers

The landing page ranks providers by CASC score across monitored endpoints and regions so teams can quickly identify strong operational signals and compare API quality across peers.

Signals

What the landing page highlights

The human page surfaces top performers, featured benchmark categories, CASC score interpretation, and methodology. The Markdown view mirrors those decision points so agents can cite the same operational context without scraping UI components.

  • Fastest median latency signal: Contentful at 33 ms.
  • Strongest CASC signal: Open Weather at 9.70 CASC.
  • Lowest outlier signal: Yapily at 0.1% outliers.
  • CASC score blends consistency, pass rate, errors, and outlier behavior into a comparable quality signal.
Methodology

How to interpret the directory

APIContext benchmark pages are generated from verified synthetic monitoring snapshots. They are not live status pages; they are citable weekly intelligence for comparing machine-facing services.

  • Use category pages to compare peer providers within a market or service type.
  • Use subject pages for domain, CASC, pass rate, p95 latency, regional, and infrastructure detail.
  • Use the comparison view to preserve selected subjects in a shareable URL.
  • Use JSON endpoints when building agents, reports, or external analyses.
