What is the datos.gob.cl API?

datos.gob.cl is Chile's national open data portal, exposing a free, key-free CKAN API with more than 3,100 datasets. Records carry a machine-readable `frequency` such as `1d` for daily, and a large share are released under CC0, which is unusually permissive for a government catalogue.

Chile's portal is compact and well-tended. An unfiltered search returns the industrial property registry from INAPI — patents, trademarks and design registrations — with eighteen attached resources, a daily refresh cadence and a CC0 licence. That combination of frequency plus genuinely public-domain licensing is rare: most national portals default to CC BY and state cadence in prose, if at all.

Two implementation details are specific to this install. The `frequency` field uses terse codes such as `1d`, `1m` and `1y` rather than ISO 8601 durations or English words, so parse accordingly. And organisation IDs are agency codes like `AY001`, not UUIDs — convenient as stable keys, but they break any assumption that a CKAN `organization.id` is a UUID. Everything is Spanish; there is no English mirror.

Quick facts

Base URL: https://datos.gob.cl/api/3/action
Authentication: No API key for reads. Publishing requires an account tied to a Chilean public body.
Rate limit: No published limit. Some records attach many resources, so keep `rows` low.
Pricing: Free. CC0 and CC BY are both common; check `license_id` per dataset.
CORS: Enabled — callable directly from browser JavaScript

Response fields

successboolean: CKAN's flag; HTTP 200 does not imply success.
result.countinteger: Total matching datasets — 3,187 unfiltered when tested.
results[].frequencystring: Terse cadence code: `1d` daily, `1m` monthly, `1y` yearly. Not ISO 8601.
results[].license_id / license_urlstring: Often `cc-zero` with a link to the Open Definition licence text — public domain, no attribution required.
results[].organization.idstring: An agency code such as `AY001`, not a UUID. Stable, but not the shape other CKAN clients expect.
results[].organization.descriptionstring: A full paragraph describing the agency's remit, in Spanish.
results[].num_resourcesinteger: Attached files. Registry datasets can carry well over a dozen.
results[].isopenboolean: True for the CC0 and CC BY records that make up most of the catalogue.

Common errors and how to fix them

HTTP 200 with success false

CKAN rejected your parameters.

Fix: Read `error.message` in the body rather than the status code.

Frequency parser fails

Values are `1d`/`1m`/`1y`, not ISO 8601 durations.

Fix: Parse the short code directly; do not feed it to a duration library expecting `P1D`.

Organisation ID fails UUID validation

Chile uses agency codes like `AY001`.

Fix: Treat `organization.id` as an opaque string across all CKAN portals.

Empty results

The query was in English.

Fix: Search Spanish terms; the index carries no English text.

datos.gob.cl API — frequently asked questions

Is the datos.gob.cl API free?

Yes. All reads are free with no key or registration. Only Chilean public bodies publishing data need an account.

What licence covers Chilean open data?

It varies, but CC0 is common — the industrial property registry returned by an unfiltered search is CC0, meaning public domain with no attribution requirement. Always confirm `license_id` on the individual record.

How often is the data refreshed?

Each record states it in `frequency` using a short code: `1d` for daily, `1m` monthly, `1y` yearly. That is machine-readable, so you can drive your harvest schedule straight from the catalogue.

Is there an English version?

No. Titles, descriptions and agency profiles are Spanish only, so search with Spanish vocabulary and translate on your side if needed.
