ProgrammableWeb

ProgrammableWeb was the original API directory and developer resource, founded by John Musser in 2005, documenting over 19,000 open web APIs and thousands of mashups and applications over 17 years of operation. It was acquired by Alcatel-Lucent in 2010, sold to MuleSoft in 2013, and ultimately shut down in October 2022 following Salesforce's acquisition of MuleSoft. The site's content is preserved through the Internet Archive's Wayback Machine.

ProgrammableWeb publishes 1 API on the APIs.io network. Tagged areas include API Aggregation, API Directory, API Discovery, Archived, and Developer Resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
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/programmableweb: open an issue to ask a question, or submit a pull request to add artifacts.
