The data — what is free, and what is available on request
Everything published on this site is free to reuse under CC BY 4.0, including commercially, with attribution. There is no signup, no key, and no rate limit to negotiate. We have recorded 4,777,202 measurements since 2026-07-25 across 46 providers and 4 regions.
What is in the dataset?
One row per probe. The core fields are below; raw rows also include the model, DNS, TCP, TLS and total timings, HTTP status and error details. Published percentiles are computed from successful timed samples in the stated window.
| Field | Type | Meaning |
|---|---|---|
ts | ISO-8601 UTC | when the probe ran |
provider | slug | which API host was probed, e.g. openai |
region | slug | one of 4 probe locations |
probe_type | network | inference | edge latency (no key needed) or time-to-first-token (needs a key) |
status | ok | error | timeout | probe outcome |
ttfb_ms | number or null | network probe: milliseconds to the first response byte |
ttft_ms | number or null | inference probe: milliseconds to the first model token |
What does the dataset cover?
Coverage by region and probe type is listed below. Inference rows exist only for providers we hold an API key for; unmeasured combinations have no estimate.

What can I use right now, for free?
- Rankings JSON — current p50/p95 and uptime per provider per region, with the timestamp it was generated at.
- OpenAPI description and an MCP endpoint, so an agent can query the data directly.
- A markdown twin of every page (append
.md), plus the whole corpus as text. - An embeddable badge that regenerates itself.
What is not published?
The site shows a rolling 24-hour window. The raw time series behind it — every individual probe, with DNS, TCP, TLS and first-byte timings separated — is retained for 90 days. Contact us to discuss a bulk export.
What can I ask for?
See a working seven-day report and its JSON. A data pilot costs $20/month for agreed provider filters, daily reports and delivery support.
- Historical bulk export — the raw series for a period, as CSV or Parquet.
- A region we do not measure yet — request an additional probe location.
- A provider we do not track — if it has a public API host, it can be measured.
- Higher-frequency probing for a specific provider or route.
Open an issue at the public repository and describe what you need. Requests that make the public dataset better get done and stay free; work that exists only for one requester is quoted individually.
Does paying change the rankings?
No. Rankings are based on measurements. Providers cannot pay for placement, ordering or omission. Paid work covers data access and additional measurements.
