Data and API documentation

Download the same published information used by the checker. Each model has separate prescription routes and market records. The download contains no visitor prescriptions.

GET https://smartspecscheck.co.uk/api/v1/models.json

This endpoint returns a complete snapshot. It accepts no prescription input and provides no server-side prescription-checking service. Keep the downloaded file if you need to reproduce a comparison later.

Response structure

generated: Build date. This does not mean every source was checked that day.
source and licence: Methodology link and the current citation statement. Quoted material remains attributable to its original publisher.
models[]: Model records with stable IDs, names, category, record URLs, prescription routes and markets.
rx_paths[]: One provider route: provider, method, official, optional country codes in markets, limits, source_url and last_verified.
limits.power_rule: sph_only uses the published sphere limits; sph_plus_cyl uses the published total-power limits. Preserve the separate cylinder, lens-type and fitting restrictions. unknown requires confirmation.
markets: Sale status, prices, retailers and checked dates by country. A model being sold in a country does not establish availability of every prescription route there.
open_questions: Unresolved points to keep beside relevant claims.

Example: inspect provider routes

const response = await fetch('/api/v1/models.json');
if (!response.ok) throw new Error('Dataset unavailable');
const dataset = await response.json();
for (const model of dataset.models) {
  for (const route of model.rx_paths) {
    console.log(model.name, route.provider,
      route.markets, route.limits, route.last_verified);
  }
}

The example uses a relative URL on this site. For an external application use the absolute endpoint above and check your environment’s cross-origin requirements.

Missing information and dates

A missing value or null means information is not recorded; it never means unlimited support. A route without listed countries does not prove worldwide availability. Check its source and notes. After 45 days the checker flags a route as stale; after 90 days a passing route is labelled unverified.

Citation and corrections

Cite the model page, named provider, original source URL and that route’s checked date. Retain country and fitting restrictions. For example: Smart Specs Check, “[model name]”, “[provider]” route, source checked [date], accessed [date].
