find_observations

Search verified species observation records.

Direct GET

For navigating agents: open the HTML page with parameters in the URL. The result is fetched and displayed without screenshots or form filling.

https://allemannsdata.com/wiki/kilder/artskart/find_observations/?taxon_id={taxon_id}&county={county}&municipality={municipality}&status={status}&from_date={from_date}&to_date={to_date}&lat={lat}&lon={lon}&radius_km={radius_km}&only_image_obs=false&page=0&page_size=20&limit=25&offset=0

Replace {taxon_id}, {county}, {municipality}, {status}, {from_date}, {to_date}, {lat}, {lon}, {radius_km}, {only_image_obs}, {page}, {page_size} with values. Remove unused optional parameters from the URL.

For software and dashboards: Read the operation descriptor. The JSON GET template is https://allemannsdata.com/wiki/api/v1/kilder/artskart/find_observations?taxon_id={taxon_id}&county={county}&municipality={municipality}&status={status}&from_date={from_date}&to_date={to_date}&lat={lat}&lon={lon}&radius_km={radius_km}&only_image_obs=false&page=0&page_size=20&limit=25&offset=0.

ParameterRequirementJSON typeDescription
taxon_idoptionalunionRestrict to one species/taxon, from search_species.
countyoptionalunionTwo-digit numeric fylkesnummer, e.g. "50" for Trøndelag. Pass the code, not a county name such as "Trøndelag". Validated against the current 15 fylke; an unknown code errors rather than returning unrelated data.
municipalityoptionalunionKommunenummer, e.g. "5035" for Stjørdal. Must be a current (post-2024) 4-digit kommunenummer; a stale/unknown code silently returns nothing useful.
statusoptionalunionRedlist/alien-species status code, e.g. "cr", "en", "hi" (codes from list_reference_codes("status")).
from_dateoptionalunionISO date (YYYY-MM-DD), inclusive range.
to_dateoptionalunionISO date (YYYY-MM-DD), inclusive range.
latoptionalunionWGS84 point and radius for a "near here" search; supply all three together. Each result gains a distance_km field and the list is sorted nearest first. The public API ignores geometry filters, so this is applied client-side over up to ~1000 fetched records; combine with taxon_id and/or county for complete coverage. Ignores page (returns the nearest page_size).

Generated JavaScript, Python and response structure

Use JSON when the user requests code, machine-readable data, value extraction or further computation. Use the HTML GET page to identify the correct source and verify parameters.

Example for generated JavaScript and Python

https://allemannsdata.com/wiki/api/v1/kilder/artskart/find_observations?taxon_id={taxon_id}&county={county}&municipality={municipality}&status={status}&from_date={from_date}&to_date={to_date}&lat={lat}&lon={lon}&radius_km={radius_km}&only_image_obs=false&page=0&page_size=20&limit=25&offset=0

Replace URL placeholders and remove unused optional parameters.

JavaScript in a dashboard

const url = "https://allemannsdata.com/wiki/api/v1/kilder/artskart/find_observations?taxon_id={taxon_id}&county={county}&municipality={municipality}&status={status}&from_date={from_date}&to_date={to_date}&lat={lat}&lon={lon}&radius_km={radius_km}&only_image_obs=false&page=0&page_size=20&limit=25&offset=0";
const response = await fetch(url);
if (!response.ok) {
  const failure = await response.json();
  throw new Error(`${failure.error.code}: ${failure.error.message} ${failure.suggestion}`);
}
const result = await response.json();
const data = result.data;

How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the find_observations lookup

  1. Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
  2. Check types, units, limits and ID formats in the parameter table.
  3. Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
