api_gate, verbatim from the file:

unknown

949 of 1252 entries carry an unknown gate. Unknown is a legal answer and it ships as unknown rather than as a guess.

API documentation

https://www.sendblue.com/api

No documentation text is reproduced anywhere on this site. Read the vendor page for the prose. The structured docs digest specced in SPEC section 3 has not been built or crawled: docs_digest is null on every entry in this build.

GitHub health

Not measured. github_url, github_stars, github_last_commit and github_archived are null on every entry in this build.

The refresh rail specced in SPEC section 7.2 has not been run. An unstamped star count is a lie, so nothing is shown rather than something stale.

On GitHub

No GitHub organisation could be tied to sendblue.com with evidence on 2026-09-15.

Recorded by the harvest: not checked: gh CLI missing or not logged in.

Jobs it can do

No job tag on this entry.

981 of 1,252 entries are untagged. An empty list here means nobody has tagged this, not that the tool does nothing. The vocabulary is closed, so a tool whose job is genuinely not in it stays blank rather than being forced into the nearest tag.
