Why apis & backend skills work in Gemini CLI
Each skill on this page is a SKILL.md file built for apis & backend work and confirmed to run in Gemini CLI. Connect your agent through MCP and Gemini CLI follows the workflow the creator encoded instead of improvising from a short prompt.
Listings are ranked by installs, upvotes and reviews, so what surfaces first is what other Gemini CLI users actually keep. Free and paid skills compete on the same page, and every listing shows its security scan result before you use a skill.

What can you do with Gemini apis & backend skills?
These are the jobs creators are actually shipping skills for in this category. Each one encodes a full workflow, so Gemini CLI follows the same method every time instead of improvising from a one-line prompt.

- Rest
- Rest API
- Graphql
- Endpoints

Choosing the right Gemini skill for apis & backend
Start with the outcome, not the label. Open the listing and read the SKILL.md preview: a good apis & backend skill states exactly what it does, what it needs from you, and what it deliberately refuses to do. Vague descriptions usually mean vague output.
Then check three things: the install count and reviews (other Gemini CLI users voting with their setup), whether the creator ships updates, and whether the skill is universal SKILL.md or agent-specific. Free skills are a fine way to test a creator's style before buying their paid work.

Why choose Agensi for Gemini skills?
Verified creators
Every paid creator is verified before they can sell, so skills come from practitioners, not scraped prompt packs.
8-point security scan
Each version is scanned for prompt injection, credential exfiltration and destructive commands before it goes live.
Free and premium together
Some skills are free, but most are paid. Paid skills show the price upfront and include future updates from the creator.
Ready when you connect
Connect your agent to Agensi once and the skill is ready to use. The latest version loads each time, and nothing is saved.
