API Tools
Open source tooling for the specifications that describe, secure and ship APIs — with the license, the specification it implements, and the semantics an AI agent needs to actually use it.

roles in the vocabulary
Building an agent?
Everything here is published as structured data — don't scrape the pages.
/tools.json is the catalog,
/roles.json is the vocabulary of what
a tool does to a specification,
/tool.schema.json is the contract,
and /llms.txt explains how to resolve
from an artifact you are holding to a tool that acts on it.
The Agent Reference covers the vocabulary in full,
and what the numbers on this site do and do not mean.
By specification
The open source tooling behind each standard, harvested from its governing organisation. Follow a standard through to standards.apievangelist.com for what it actually specifies.

All tools by hiring demand
Ranked by the number of distinct companies whose job postings name the tool, from the API Evangelist demand corpus. This is a demand signal — evidence of hiring, not of deployment — and counts are only comparable within a single quarter.
Precision is a separate axis: how trustworthy the tool's name is as a search term in a job-postings corpus, independent of how many companies said it. A name that is also an ordinary word scores low however large its count. Filter on both — low precision with a high count is where a number is least safe to quote.
