What people ask Perigon 9

The questions people put to an LLM, and the jobs they hand an agent, that Perigon's APIs answer — each one linked to the operation that does it. Generated by API Evangelist

Perigon News & Stories API Search news articles “How do I search news articles by keyword, source and date range?” Queue articles for a background refresh “How do I ask for updated data on a batch of articles I already have?” Check an article refresh job's status “Is my article refresh job finished yet?” Peek at cached refreshed article data “Can I see already-cached refreshed article data without starting a new job?”
Perigon Watchlists API List watchlists “Which watchlists of people and companies can I use?” Create a watchlist of people and companies “How do I build a watchlist of executives and companies to track?” Resolve watchlist names “If a private watchlist and a public one share a name, which does a lookup by name return?” Get a watchlist by ID “Who is on a particular watchlist?”
Perigon Supplemental Endpoints API Search tracked companies “Can I look up a company by its stock ticker or domain?” Search journalists “How can I find journalists who cover a specific topic?” Get a journalist's profile “Can I get more detail on a journalist using the ID from an article?” Search known people “How do I look up a public figure mentioned in the news?”

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/perigon: open an issue to ask a question, or submit a pull request to add artifacts.
