List changes

Official changes, newest first.

GET /api/v1/changes

Filter across labs and products. Use the returned cursor to continue through the feed.

Example

TypeScript

const response = await fetch("https://claudemon.com/api/v1/changes?limit=3");
if (!response.ok) throw new Error(`HTTP ${response.status}`);
const { data } = await response.json();
console.log(data);

import requests

response = requests.get("https://claudemon.com/api/v1/changes?limit=3", timeout=30)
response.raise_for_status()
print(response.json()["data"])

curl "https://claudemon.com/api/v1/changes?limit=3"

TypeScript and JavaScript use native fetch. Python uses requests (pip install requests).

Live response from this deployment, fetched when this page rendered.

Newest first by the ordering date: the upstream publication time, else its date, else when ClaudeMon first saw it. Ties go by ID.

dataobject[]: This page of change objects.
next_cursorstring or null: Pass it as cursor for the next page. null on the last page.
has_moreboolean: Whether another page follows.

Meta update projection

metaobject (optional): Additive convenience projection for supported Meta updates only. Omitted for other labs and for monitoring or inventory kinds such as component and source.repository. Existing change fields and IDs remain canonical.
meta.timestampstring: UTC ISO 8601 instant. Uses source_published_at only when precision=instant; otherwise uses observed_at. A date-only source never invents a publication time.
meta.timestamp_basisstring: published for an upstream publication instant, otherwise observed for the first observation.
meta.providerstring: Always Meta.
meta.productstring: The current catalog display name for product, or Meta when no catalog product matches. The canonical product ID remains unchanged.
meta.update_titlestring: The same upstream title as title. Treat it as untrusted text.
meta.source_urlstring: The same source URL as source_url on the change.
meta.update_typestring: Model Listing for model.listing, Incident for incident, or Changelog for release, changelog, source.tag or source.commit.

Headers

ETag: A strong validator. See caching.
Cache-Control: public, max-age=30, s-maxage=60, stale-while-revalidate=300.
Link: The next page with rel="next", when there is one.

Errors

invalid_parameter: An unknown lab, product or kind, a bad since, include other than body, or limit outside 1 to 100.
invalid_cursor: The cursor is malformed or from other filters.
