What it does
Astrologer API is a service on the Kerykeion engine that computes natal charts, synastry, transits, composites, returns and moon phases and returns SVG diagrams and JSON data. The repository holds an `astrologer-api` skill for agents and MCP server code. The skill covers all 31 RapidAPI endpoints, request examples, chart options, SVG responses, server-side Python and JavaScript clients and error handling. Calls need your own RapidAPI key, kept on the server. Requests go to `astrologer.p.rapidapi.com/api/v6`.
Who it is for. Developers of astrology apps and compatibility services who wire up the API through an agent. Needs a RapidAPI key.
Good fit when
- An app needs a natal chart as SVG plus data for the interface.
- Synastry and a compatibility score for a pair.
- Current transits and moon phase on a page.
- A server-side Python or JavaScript client built from ready examples.
Not a fit when
- An offline calculation without an external service is needed, as the API is paid and networked.
- The key would go into browser client code.
- Astrological results would be used as health or money advice.
Example request
Use the astrologer-api skill and write a server-side natal chart call with the dark theme, taking the key from an environment variable.Limitations
The skill does not replace a subscription: a RapidAPI key is needed for every request and limits depend on the plan. Never embed the key in client code; keep it on the server. Requests carry a person's name, birth date, time and place, which is personal data. The repository is AGPL-3.0, which matters when hosting your own copy. Astrological results are not suitable as health or money advice. The last commit is from 6 November 2026.
How to disable. Delete the `astrologer-api` folder from the agent skills directory and revoke the RapidAPI key if it is no longer needed.
FAQ
How many endpoints does the skill cover?
All 31 RapidAPI endpoints: charts, chart data, returns, transits, compatibility, moon phases and helpers.
Which headers does a request need?
`X-RapidAPI-Key` with your key and `X-RapidAPI-Host: astrologer.p.rapidapi.com`.
What does a chart endpoint return?
JSON with a status, SVG markup in `chart` and data in `chart_data`. With `split_chart` the wheel and grid arrive separately.
Can the API be called from a browser?
No. The key must stay on the server, which the skill requires.
Does the repository include an MCP server?
Yes, the `mcp` folder holds server code with chart and moon phase tools. The skill remains the main way to connect.
