Authentification
Envoyez une clé d'API en tant que jeton du porteur (bearer token). Cet endpoint n'indique pas de permission spécifique dans la spécification, attribuez donc à votre clé le minimum requis et vérifiez la réponse plutôt que de faire des suppositions.
Cet endpoint ne prend aucun identifiant d'organisation. Votre clé identifie déjà l'organisation à laquelle elle appartient, et la réponse y est limitée.

Détails
The site's newest Core Web Vitals reading — LCP, CLS and INP for its **homepage**, with the "good / needs improvement / poor" band for each and for the reading as a whole. Backs the Performance tab's vitals card and the free SEO Basics tile, both of which are sold as included on every plan and every site. RLS-scoped to a site the caller can view (`sites.view`); an out-of-scope or unknown id is a `404`, exactly like `getSite`. **Homepage only, by design.** Every surface that sells this sells *homepage* Core Web Vitals. Measuring every URL of every site is a different product. **Collection is asynchronous.** Readings are taken off the request path by a scheduled collector and read back here — a live Lighthouse run would be a 20-second uncached external call on a tab that mounts for every site (CLAUDE.md §2.16). Until a site has been measured, `available` is `false`, every metric is `null` and every band is `unknown`. **`source` must be rendered.** A `lab` reading is a synthetic Lighthouse run; a `field` reading is what real Chrome users experienced (Chrome UX Report) and is what Google ranks on. Field data does not exist for sites below CrUX's traffic threshold — which is most low-traffic sites — so `lab` is the coverage tier. Presenting a lab score as though real users produced it is a false claim about what visitors experienced, so clients must label which one they are showing.

Réponse
| Nom | Type | Obligatoire | Qu'est-ce que c'est |
|---|---|---|---|
available | boolean | Oui | Whether any vitals reading exists for this site yet. |
url | string | Oui | The exact URL measured. Empty when unavailable. |
source | string<field, lab, > | Oui | `field` = Chrome UX Report (real users, what Google ranks on); `lab` = a synthetic Lighthouse run. Clients MUST label which is shown. Empty string when unavailable, following `p… |
field_available | boolean | Oui | Whether real-user (field) data exists for this site at all, independent of which reading is returned — so the UI can say "no real-user data yet" while still showing the lab number. |
lcp_ms | object | Oui | Largest Contentful Paint, p75, milliseconds. Good ≤ 2500, poor > 4000. |
cls_milli | object | Oui | Cumulative Layout Shift, p75, in **thousandths** (0.083 → `83`). An integer so no band comparison is ever made against a float at the 0.1/0.25 boundaries; clients render `cls_mi… |
inp_ms | object | Oui | Interaction to Next Paint, p75, milliseconds. Good ≤ 200, poor > 500. INP replaced First Input Delay as a Core Web Vital in March 2024; FID is retired and is deliberately not re… |
ttfb_ms | object | Oui | Time to First Byte — a diagnostic, not a Core Web Vital. |
fcp_ms | object | Oui | First Contentful Paint — a diagnostic, not a Core Web Vital. |
performance_score | object | Oui | Lighthouse performance score, 0–100. Always `null` on a `field` reading — the Chrome UX Report computes no score, and inventing one would present a number Google never produced. |
accessibility_score | object | Oui | Lighthouse accessibility score, 0–100 (docs/85 §2.1). Lighthouse computes all four of its categories from a **single** page load, so this costs about a second on a 10–30 s run —… |
best_practices_score | object | Oui | Lighthouse best-practices score, 0–100 — mixed content, deprecated APIs, console errors. `null` on a `field` reading. |
seo_score | object | Oui | Lighthouse SEO score, 0–100. `null` on a `field` reading. |
stack_packs | string[] | Oui | The technology stacks Lighthouse detected on this run (`wordpress`, `woocommerce`, …). **Ids only.** Lighthouse also ships stack-specific remediation *text*; that is untranslate… |
