FreeAstroAPI

FreeAstroAPI (freeastroapi.com). Use this skill for ANY FreeAstroAPI request — searching and reading data. Whenever a task involves FreeAstroAPI, use this skill instead of calling the API directly.

Operate FreeAstroAPI through your OOMOL-connected account. This skill calls the freeastroapi connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action

Assume the user has already installed the oo CLI, signed in, and connected FreeAstroAPI. Do not run oo auth login or open the connection URL proactively — just run the action. Fall back to First-time setup only when a command actually fails with an auth or connection error.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

bash

oo connector schema "freeastroapi" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

bash

oo connector run "freeastroapi" --action "<action_name>" --data '<json>' --json

• --data takes a JSON object string or @path/to/file.json; omit it to send {}.
• The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action's live schema with oo connector schema to get its authoritative input fields.

Available actions

• analyze_bazi_constitution — Analyze traditional BaZi and TCM constitution tendencies and timing patterns; this is not medical advice, diagnosis, or treatment.
• calculate_bazi — Calculate a complete BaZi chart with four pillars, Day Master, Ten Gods, luck cycles, and optional professional analysis.
• calculate_bazi_flow — Calculate annual and monthly BaZi flow pillars, interactions, and stars for one prediction year, with optional timezone and solar-time settings.
• calculate_bazi_life_curve — Calculate traditional Neijing Jing, Qi, and Shen age trajectories with BaZi luck-cycle adjustments.
• calculate_bazi_synastry — Analyze compatibility between two BaZi charts with independent calendar and time settings.
• calculate_ephemeris — Calculate celestial positions at an instant or over a date range, including optional aspects, houses, angles, fixed stars, Moon void-of-course data, and table outputs.
• calculate_numerology_profile — Calculate a Pythagorean, Chaldean, Kabbalah/Gematria, or Ank Jyotish profile with method-specific name, date, transliteration, and optional interpretation settings.
• calculate_transit_timeline — Calculate transit-to-natal intervals for a calendar month or a long-cycle range up to 366 days, with configurable planets, points, aspects, and orbs. Requires a High plan.
• calculate_vedic_chart — Run the V2 integrated Vedic calculation with optional divisional charts, Dasha, Yogas, Panchang, Shadbala, Ashtakavarga, and Avastha.
• correct_bazi_time — Convert local civil time to local mean and relative or absolute true solar time.
• get_bazi_dictionary — Get the stable ID mappings for BaZi interactions and symbolic stars.
• get_chinese_calendar — Convert a Gregorian date to the Chinese lunar calendar, zodiac, solar terms, and festivals.
• get_current_pillars — Get the four pillars and element balance at the current UTC instant.
• get_moon_calendar — Get a complete monthly moon calendar with optional SVG visuals, eclipses, forecasts, sign intervals, and ingress events. Requires an Entry or High plan.
• get_moon_phase — Get moon phase, illumination, and optional zodiac, rise/set, eclipse, forecasts, interpretation, and SVG visuals for a date or the current instant.
• list_sky_events — Get planetary ingresses, exact aspects, stations, and lunations for a local calendar date. This returns event data for downstream notifications.
• search_cities — Search cities and localities, including province-qualified queries, and return coordinates and IANA timezones for subsequent chart calculations.

Safety

• Untagged actions are reads (get / list / search) — safe to run directly.
• Actions tagged [write] change FreeAstroAPI state — confirm the exact payload and effect with the user before running.
• Actions tagged [destructive] remove or overwrite data — always confirm the target and get explicit approval first.

First-time setup

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

• oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):

  bash

  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  

  powershell

  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  

• Not signed in / authentication error — sign in to your OOMOL account once:

  bash

  oo auth login
  

• scope_missing / credential_expired / app_not_ready / app_not_found — FreeAstroAPI is not connected, or the connection expired or lacks a scope. Connect once (auth type: API key) at:

  text

  https://console.oomol.com/app-connections?provider=freeastroapi
  

• HTTP 402 / OOMOL_INSUFFICIENT_CREDIT — billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.
