Data & API
The observatory's data can be downloaded as CSV files or queried through the JSON API.
The references for citing the data or the project are available on the About page.
JSON API
Public, read-only endpoints. All of them return UTF-8 encoded JSON.
| Endpoint | Parameters | Description |
|---|---|---|
api/palabra.php |
word (required) |
Full profile of a lemma: occurrences, frequencies, forms, weekly time series, breakdown by outlet and section. Example |
api/buscar.php |
q (required), mode=contains|prefix|exact, media, section, from, to, lang=en|other, p |
Occurrence search, paginated (25 per page). Example |
api/comparar.php |
words (comma-separated, max 5) |
Frequency-per-million time series for several lemmas. Example |
api/tendencias.php |
tipo=top|rising|new, periodo=week|month|quarter|year, dias=7|30|365 |
Rankings: most frequent, rising or new anglicisms. Example |
api/sugerencias.php |
q (required, min. 2 characters) |
Lemma autocomplete. Example |
Fair use: the API is intended for one-off queries and prototypes, and enforces a per-IP rate limit (20-60 requests per minute depending on the endpoint; exceeding it returns 429). For large-scale analyses, please download the monthly CSV files.
Monthly CSV files
One file per month with the anglicisms extracted by Lázaro, hosted on GitHub.
