CF x-api

An X API alternative and Twitter API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no OAuth and no developer application. Use when the user wants to search X posts by keyword, hashtag, or advanced operators (from:, to:, since:, until:, min_faves:, filter:), scrape an X/Twitter profile by handle, pull a user's posts, replies, followers, or followings, fetch a single post with its replies or reposters, read an X List's members or posts, check trending topics by country, or search for X accounts by name. Also covers building an X data pipeline, social listening, competitor monitoring, hashtag tracking, or follower export without the official X API's pricing tiers or app-review process.

What is at stake

Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.

Exfiltration medium severity

Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.

If you install

The instructions or scripts send data out: environment variables, keys, file contents, chat history. You may never notice, because the agent performs the upload as "part of the task".

For the author

If the upload is not needed for the task, remove it: catalogs flag such skills and delist them. If it is needed, name the destination explicitly, say what leaves the machine, and give the user a switch.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
