What it does
Astrologer API is an agent skill from g-battaglia/Astrologer-API. Integrate the hosted Astrologer API through RapidAPI for SVG charts, astrology data, Moon phases, planetary hours and XML context. Use when writing or debugging clients for this service.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/clients-and-errors.md`, `references/options-and-responses.md` and `references/requests.md`).
It sits in Development. The repository describes itself as: High-precision Astrology API powered by the Kerykeion engine. Natal charts, synastry, transits, composites, returns, and moon phases as SVG + JSON. The licence is AGPL-3.0.
When your agent uses it
- Debugging clients for this service
Example prompts
- “/astrologer-api”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 75f8011. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
astrologer.p.rapidapi.com
Also links to:
kerykeion.netrapidapi.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Astrologer API loads about 1.9k tokens when it runs, and up to ~7.9k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 818 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Integrate the hosted Astrologer API through RapidAPI for SVG charts, astrology data, Moon phases, planetary hours and XML context. Use when writing or debugging clients for this service.
Astrologer API
Use this skill for the public RapidAPI catalogue. It covers the 31 endpoints below, not every capability in the source repository. Follow the user's requested feature and language; do not add unrelated calculations or infrastructure.
Connection
- Base URL:
https://astrologer.p.rapidapi.com/api/v6 - All listed endpoints use
POSTwith a JSON body, including current-time endpoints. - Headers:
X-RapidAPI-Key,X-RapidAPI-Host: astrologer.p.rapidapi.com, andContent-Type: application/json. - Read the consumer key from the caller's environment or existing secret store. Keep it on the application's server; never embed it in browser code, examples or logs.
- The consumer key is not the provider's proxy secret. A client only needs the consumer key.
- Obtain a key through the subscription page. Account changes and purchases remain the user's decision.
The playground provides schemas and examples. For these routes select version 6.0.0. Older guides using /api/v5 describe a different contract; do not copy their field aliases into new requests.
Select an endpoint
Paths below are relative to the base URL. Choose data when no image is needed, charts when an SVG is needed, and context when the consumer needs XML for a model prompt. Context endpoints return structured input, not generated predictions or prose.
| Group | Path | Main input | Result |
|---|---|---|---|
| Charts | /chart/birth-chart | subject | SVG + chart data |
| Charts | /chart/transit | first_subject, transit_subject | SVG + chart data |
| Charts | /chart/synastry | first_subject, second_subject | SVG + chart data |

| Charts | /chart/solar-return | subject, return search start | SVG + chart data |
| Charts | /chart/lunar-return | subject, return search start | SVG + chart data |
| Charts | /now/chart | Options or {} | Current UTC sky SVG + data |
| Chart Data | /chart-data/birth-chart | subject | chart_data |

| Chart Data | /chart-data/synastry | first_subject, second_subject | chart_data |
| Chart Data | /chart-data/composite | first_subject, second_subject | chart_data |

| Chart Data | /subject | subject | subject |

| Moon Phase | /moon-phase | Date, time, coordinates, timezone | moon_phase_overview |
| Moon Phase | /moon-phase/now-utc | Options or {} | Current moon_phase_overview |
| Moon Phase | /moon-phase/context | Date, time, coordinates, timezone | XML + moon_phase_overview |
| Moon Phase | /moon-phase/now-utc/context | Options or {} | XML + current Moon data |
| AI Context | /context/birth-chart | subject | XML + chart_data |
| AI Context | /context/transit | first_subject, transit_subject | XML + chart_data |
| AI Context | /context/synastry | first_subject, second_subject | XML + chart_data |
| AI Context | /context/composite | first_subject, second_subject | XML + chart_data |
| AI Context | /context/lunar-return | subject, return search start | XML + return data |
| AI Context | /context/solar-return | subject, return search start | XML + return data |
| AI Context | /now/context | Options or {} | XML + current subject |

Choose the relevant reference
- Requests and examples: subject fields, time zones, paired charts, returns, Moon and Sun requests, current-time calls, and dominant planets.
- Options and responses: zodiac and house settings, points and aspects, SVG customization, response field locations, and reuse of computed data.
- Clients and errors: server-side Python and JavaScript clients, timeout and retry decisions, and checks before shipping an integration.
Read the relevant sections for the requested feature. The examples are complete JSON bodies for their named endpoints; they use synthetic subjects.
Start with a small request
Keep subject (or both subjects) first in examples, then computation settings, then rendering options. Inside a subject show name, date, time and location before advanced settings.
POST /api/v6/chart/birth-chart
{
"subject": {
"name": "Ada",
"year": 1990,
"month": 5,
"day": 1,
"hour": 10,
"minute": 0,
"city": "Rome",
"latitude": 41.9028,
"longitude": 12.4964,
"timezone": "Europe/Rome"
},
"theme": "classic"
}For /chart-data/birth-chart or /context/birth-chart, use the same subject and remove theme. The first returns chart_data; the second also returns an XML context string.
Contract essentials
- A subject requires
year,month,day,hour,minuteandcity;nameis optional. Use complete coordinates plus an IANA timezone, or GeoNames lookup. Do not invent an unknown birth time or location. - Synastry, composite and compatibility use
first_subjectandsecond_subject. Transit usesfirst_subjectandtransit_subject. Moon and Sun endpoints use flat date/location fields. - Requests use
timezone,longitude,latitude; computed subjects usetz_str,lng,lat. Response objects are not valid request subjects without mapping and filtering. - Computation options belong at request level on chart-family endpoints; zodiac, house and fixed-star settings belong inside each subject. Rendering options belong only on chart endpoints. Extra fields are rejected.
- Use canonical point names such as
Mean_LilithandMean_North_Lunar_Node. Keep fixed stars insubject.active_fixed_stars, notactive_points. - Choose new subjects or precomputed
chart_datadeliberately. Where supported,chart_datatakes precedence and calculation options do not recompute it. - Require HTTP 200 and
status: "OK", then check the payload needed by the feature: SVG, chart data, XML, Moon data, Sun times or dominants. Do not mistake an empty successful response for a working integration. - Handle 422 by fixing the body, 401/403 by checking credentials and subscription, and 429/503 with bounded retries that respect
Retry-After. Do not silently change plans or loop indefinitely.
Use the API README and the endpoint's playground schema for additional fields. Test connectivity with a synthetic subject before sending real birth details.
