Benchmark API

Per-plugin and per-theme WordPress performance scores from the only public dataset of its kind — 37,000+ plugins benchmarked across 3 contexts (activation, homepage, wp-admin).

Endpoints

GET /wp-json/mwf-api/v1/plugins/{slug}

Returns benchmark data for a WordPress.org plugin.

GET /wp-json/mwf-api/v1/themes/{slug}

Same shape, for WordPress.org themes.

GET /wp-json/mwf-api/v1/me

Returns your current tier, quota, usage, and reset date. Always works — even when over quota.

Response notes

• Contexts may be null if a plugin couldn't be measured in that scenario (e.g. an admin-only plugin has no homepage row). Treat null as "not measured", not "no impact".
• benchmarked: false means the slug is known but hasn't been benchmarked yet. 404 means the slug isn't in the dataset at all.
• Memory deltas in KB, TTFB in milliseconds, queries are raw counts — all measured against a clean WordPress baseline.
• Speed grade is computed from activation memory + query deltas on a logarithmic scale (A = ≤8MB / ≤4 extra queries; F = catastrophic).
• Rate-limit headers: X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset on every successful response.

Status codes

• 200 — OK
• 401 — missing or invalid API key
• 403 — key revoked or suspended
• 404 — slug not in dataset
• 429 — monthly quota exceeded

Data freshness

Benchmarks are re-run as plugins update. The benchmarked_at field tells you when the row you're reading was last measured. Responses are not edge-cached (every request is authenticated against your quota); cache on your side if you need to absorb spiky traffic.
