--- title: "Audit planet clearance from house cusps across every 12-house system" method: POST path: "/api/astro/house-boundary-proximity" tags: ["Calculations"] --- # Audit planet clearance from house cusps across every 12-house system `POST /api/astro/house-boundary-proximity` ## Request - Base URL: `https://api.cosmicephemeris.com` - URL: `https://api.cosmicephemeris.com/api/astro/house-boundary-proximity` - Auth: one of: - HTTP bearer - API key in header `x-api-key` Calculates one exact chart and measures 1–10 selected planets against every available 12-house system in Cosmic Ephemeris's fixed inventory. Each system row returns the assigned house, preceding and following cusp, two-sided angular distance, normalized within-house position, nearest-cusp ties, and an inclusive caller-declared threshold flag. Undefined geometries remain explicit unavailable rows; Gauquelin's 36 sectors are excluded and no fallback or system substitution occurs. The result does not reinterpret or reassign cusp-near planets and makes no recommendation, interpretation, prediction, or practitioner-preference claim. One standard quota unit per admitted request; failed or timed-out admitted attempts are not refunded. Do not automatically retry. Historical mode uses an explicit BCE/CE date object and UT1 conventions. Its response is the versioned historical envelope, not the modern UTC envelope. Read result for calculation fields and metadata for limits and uncertainty. ## Headers - `X-Cosmic-Ephemeris-Receipt` 'v1' ## Request body - union - HouseBoundaryProximityRequest - `birth` HouseSystemReadinessBirth, required - `date` string, date, required: Valid Gregorian YYYY-MM-DD local civil date, inclusive 1800-01-01 through 2200-12-31.

Invalid attempts reaching quota reservation consume one unit. - `401`: Missing, invalid, revoked API key or unavailable activated key owner. Dashboard cookies do not authenticate calculation routes. - `403`: Origin not allowed by production CORS policy. Server-to-server requests can omit Origin. - `429`: Monthly quota exhausted, per-user two-request concurrency reached, or nginx rate/connection admission refused. Retry-After: 2 is sent for application per-user concurrency only, not a promise that monthly quota resets in two seconds. - `502`: Engine unavailable, unsuccessful internal server response or invalid upstream JSON. No engine internals are exposed. - `503`: Four-request global calculation pool full (Retry-After: 2), maintenance or upstream service unavailable. - `504`: Application engine timeout: 15 seconds normally; planetary events, house ingresses, aspect windows, event calendar, eclipse geometry, electional search, and event-rule search use 30 seconds; Nakshatra Timeline plus the explicitly enumerated readiness, robustness, location, uncertainty, and electional-audit family use 60 seconds. Timer includes response-body parsing; an admitted timeout consumes quota. --- [API](https://skmtc.dev/cosmicephemeris/apis/cosmic-ephemeris-calculation-api.md) · [All operations](https://skmtc.dev/cosmicephemeris/apis/cosmic-ephemeris-calculation-api/llms.txt) · [OpenAPI document](https://skmtc.dev/cosmicephemeris/apis/cosmic-ephemeris-calculation-api/revisions/f041e924cea3?raw)
