Google PageSpeed Insights for one public URL: the Lighthouse scores (performance, seo, accessibility, best-practices), the lab Core Web Vitals (FCP, LCP, CLS, TBT, Speed Index), the CrUX field data when Google has it (LCP, INP, CLS), and the top five opportunities with estimated savings. Mobile by default. A run takes 10 to 40 seconds and is cached for an hour. Keyless calls share Google's quota, so a busy moment is a 503.

Translate an SRT or WebVTT subtitle file into another language. Only the cue text is translated; every cue number, timing line and header is copied exactly, and the output is checked to parse back to the same cues and timings, or it is refused unpaid.

SQL from a question and a schema (CREATE TABLE statements or a JSON description of tables and columns), for postgres (default), mysql, sqlite or bigquery. The tables and columns used are checked against the schema; a query that does not match it is retried once, then refused. Writes (INSERT, UPDATE, DELETE, DDL) are refused unless allowWrite is true. The query is not run.

Subdomains of a domain seen in certificate transparency logs: each name with the first and last certificate dates, the issuer of the newest certificate, and wildcard entries flagged.

Only public certificates are listed.
