AstroWay Core astrology missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

astroway

astroway_account_status

Check current API key status: tier, credit balance, rate limits, monthly cycle reset. Run this BEFORE invoking expensive endpoints (Tier 4+ at 100+ credits, Tier 6/7 at 500-5000 credits) to confirm the user has budget. Returns plain-text human-readable summary.

astroway_agent_tools

Tool definitions for an agent framework, generated from the live OpenAPI document, so the schema a model fills is the schema the endpoint validates. `format=openai` (default) returns `{ type, function }` objects you can spread straight into a chat completion; `format=anthropic` returns `{ name, description, input_schema }`. The objects carry nothing of ours: how to call each tool lives in a separate `executors` map keyed by tool name, because an unexpected key inside a vendor tool object is a 400 at their end. [Group: Agent Platform] [Endpoint: GET /v1/agent/tools] [Cost: see your plan — endpoint not in the public credit manifest]

astroway_calendar_planetary_hours

Chaldean planetary hours for a date and place: 12 from sunrise to sunset and 12 from sunset to sunrise, so an hour is rarely 60 minutes. `startHour` and `endHour` are decimal local hours. Send `atLocalHour` (decimal local time, e.g. 15.2 for 15:12) to have the hour containing it marked `isCurrent`; without it no hour carries the field, because the answer is cacheable and a flag from the server clock would be stale by the time it renders.

astroway_content_localization_translate_astro

Translate one text into any of 21 languages with astrology-domain glossary pinning. Source defaults to English; pass source_lang to override. Credits: 15 + ceil(chars/40). Max 3000 chars. [Group: Content Localization] [Endpoint: POST /v1/translate/astro] [Required: text, target_lang] [Cost: 16 credits (Tier 1)]

astroway_content_localization_translate_batch

astroway_geo_acg_best_places

Rank cities against the astrocartography lines of a chart for one of the 19 life categories. Distance to a line is computed from the body hour angle and altitude rather than against a discretised polyline, so it is exact: the distance to a horizon line IS the altitude in degrees of arc, and a meridian line offset is the hour angle times cos(latitude). Supportive and challenging totals are returned separately with every contributing line and its distance, so a strong-but-turbulent city is distinguishable from an average one. Bundled GeoNames set of 34,028 places above 15,000 people. [Group: Astro-Geography] [Endpoint: POST /v1/acg/best-places] [Cost: 50 credits (Tier 3)]

astroway_geo_acg_countries

Which countries the bundled city list can rank, and how many qualifying cities each has. Asking for a country with two cities and getting two results should not look like a bug. [Group: Astro-Geography] [Endpoint: GET /v1/acg/countries] [Cost: 5 credits (Tier ½)]

astroway_geo_acg_line_report

One line in full: its geometry, every life area it touches with weight and polarity, and the interpretation text for that planet-and-angle pair. Rising and setting curves arrive as several disjoint segments; all of them are returned. [Group: Astro-Geography] [Endpoint: POST /v1/acg/line-report] [Cost: 20 credits (Tier 2)]

astroway_geo_geodetic

Convert geographic coordinates to geodetic chart degrees (Sepharial method): each longitude maps to a zodiac degree on the Earth's surface. [Group: Astro-Geography] [Endpoint: POST /v1/geodetic] [Required: latitude, longitude] [Cost: 10 credits (Tier 1)]

astroway_geo_local_space

Calculate local space chart: azimuth and altitude of each planet from a given geographic location at the birth moment. [Group: Astro-Geography] [Endpoint: POST /v1/local-space] [Required: date, time, latitude, longitude] [Cost: 50 credits (Tier 3)]

astroway_geo_parans

Crossing points of two A*C*G lines: the places where two planets were simultaneously angular. Returns every planet-to-planet crossing with its coordinates. [Group: Astro-Geography] [Endpoint: POST /v1/parans] [Required: date, time, latitude, longitude] [Cost: 50 credits (Tier 3)]

astroway_geo_parans_star

Latitudes where a fixed star and a planet are angular at the same moment, which is how Brady tabulates a paran: not a place, a latitude. Twelve event pairs per star and planet (rise, set, culminate, anticulminate, minus meridian against meridian, which is a shared right ascension rather than a paran). Each row carries the houses of the technique in plain form: which body does what, the latitude, and the meridian where it happens at this chart moment. Solved on hour angles rather than by intersecting map polylines, so the latitude is exact rather than quantised to the polyline step. [Group: Astro-Geography] [Endpoint: POST /v1/parans/star] [Cost: 50 credits (Tier 3)]

astroway_geo_phase_return

Find dates when a planet returns to its same synodic phase relative to the Sun (e.g. next Venus heliacal rising, next Mars retrograde station). [Group: Astro-Geography] [Endpoint: POST /v1/phase-return] [Cost: 100 credits (Tier 4)]
