HRUM Catalog

Same models, two products — if you don't need memory, use the original models at resale prices; if you want an AI that remembers each user, just add the ridm/ prefix to model.

Resale price = cost × exchange rate × 1.10 · RIDM = resale price × 1.30 (memory engine and automatic recall included)

AI Saju Reading, Manseryeok and Compatibility APIs are included too. OpenAI SDK compatible, Korean payments, free credits.

Products

RIDM Memory API

— The same models plus a memory engine (ridm/*). For requests with the same endUserId, the server saves and recalls past context automatically (recalled context is billed as input tokens). OpenAI SDK compatible — just add the ridm/ prefix to model.

LLM API

— 39 OpenAI · Google · Anthropic models, unchanged. GPT, Gemini, Claude and more — 39 models with one key, original responses with no memory layer (resale). Pay in KRW, one credit balance.

AI Saju Reading · Memory

— Conversational readings. We host each end user's conversation memory, so a returning user picks up where they left off.

AI Saju Reading

— Single readings. An AI that has our own Saju (Four Pillars of Destiny) engine's calculations and interpretation rules reads the chart and gives tailored interpretation and advice. The Saju AI also includes Zi Wei Dou Shu, astrology, Tarot and Dream Interpretation AIs — call them all together, or just the one you need.

Manseryeok

— The full natal chart plus Saju Identity. Takes a birth date and time and calculates the chart from Manseryeok (the Korean Four Pillars calendar), based on solar terms. Saju Identity (Samjae, Sinsal, Gongmang, root strength, seasonal strength, 10-year and annual luck timeline, Saju MBTI) comes back in the same call.

Lifetime Saju

— Life readings by topic. Calculates the natal chart from a birth date and time and returns reading paragraphs on 7 topics: personality, wealth, career, love, health, relationships and advice. You can add astrology and Zi Wei Dou Shu layers.

Zi Wei Dou Shu chart

— 12 palaces, 14 main stars, four transformations. Calculates the Zi Wei Dou Shu (Purple Star) chart from a birth date and time: 12 palaces, main and assistant stars, birth-year transformations, decade and annual periods. Birth time is required. With readings:true, reading paragraphs are added (+₩20, ₩70 in total).

Today's Saju

— Day pillar summary and today's fortune. Returns the day pillar of today (or a date you choose) and how it relates to your Day Master, today's MBTI mode, this year's flow, lucky colors, foods and keywords, good and bad hours, and fit for activities. Send temperature and weather to get outfit tips; with mbtiBehavior:true, MBTI behavior patterns are added.

Dream Interpretation

— Dream symbol matching. Finds symbol words in a user's dream story using HRUM's own dream symbol lexicon and returns them by prominence. No charge when no symbol is found.

Tarot

— 78 cards · card count or spread · card images. Choose a card count (1–10) or a spread, and it draws from the 78-card deck, returning upright or reversed, keywords, meanings and the card image URL. Same price per call whatever the card count, and a seed lets you draw the same result again. For interpretation, pass the cards to the Saju AI or to the LLM API.

Compatibility

— Relationship analysis. Analyzes two people's Saju compatibility (Five Elements, Heavenly Stems and Earthly Branches, intimacy symbol table) together with their zodiac compatibility, and returns an overall score and reading paragraphs.

Astrology Total

— All of Western astrology in one call, like Manseryeok. One birth date and time returns the whole Western astrology chart: 10 bodies from the Sun to Pluto (sign, degree, retrograde, house), the nodes, Ascendant and MC, houses (4 systems), aspects and dignities. Reading paragraphs HRUM wrote in advance (dignities and aspects) are included at no extra charge. Send a date to add transits and secondary progressions, or another person's birth data to add the aspects between you (synastry), in the same response. Adding blocks keeps the same price per call.

Fortune Flow

— Numbers for 10-year, annual and monthly luck graphs. One birth date and time returns the numbers to graph the flow of 10-year luck cycles (Daeun), annual luck (Seun) and this year's monthly luck: cumulative lines and each character's share, the five god names, combinations, clashes and punishments between luck and natal chart (rule IDs), released combinations, and input for overlaying compatibility. Same per-call price as Manseryeok.

Face measurement

— Face landmarks → measurement keys · classic face reading records. Instead of a photo, send face landmarks extracted on the user's device (MediaPipe, 478 points) and get measurement keys such as ratios and angles, plus the classic face reading records that match those values. We don't receive photos or store landmarks. ₩0 if no measurement key applies. ₩33 incl. VAT.

Palm measurement

— Hand landmarks and palm lines → measurement keys · classic palm reading records. Instead of a photo, send hand landmarks extracted on the user's device (MediaPipe, 21 points) and palm lines, and get hand shape and main line measurement keys, plus the classic palm reading records that match those values. We don't receive photos or store landmarks. ₩0 if no measurement key applies. ₩33 incl. VAT.

Face reading

— One face photo → a face reading. Reads traditional face reading from one face photo (or the same face landmarks as Face measurement), for fun and reference. Photos are handled in memory only and never stored. Photos that appear to show a minor are not read. Filtered photos and errors are ₩0. ₩55 incl. VAT.

Palm reading

— One palm photo → a palm reading. Reads traditional palmistry from one palm photo, for fun and reference. Also accepts palm lines the user traced. Photos are handled in memory only and never stored. Photos that appear to show a minor are not read. Filtered photos and errors are ₩0. ₩55 incl. VAT.

Name calculation

— Stroke counts, 81-number system, sound elements (no AI). From a Korean name (and its Chinese characters if known), calculates the flow of sound elements, stroke counts, the four frames of the 81-number system, character-source elements and Yongsin (favorable element) support, and returns them with the supporting rule IDs. No AI is used, so the same name always gives the same result. ₩11 incl. VAT.

Name reading

— Name calculation plus AI interpretation. Adds AI-written interpretation based only on the name calculation values. No charge if the AI interpretation fails. ₩22 incl. VAT.

Image Generation API

— GPT-Image · Nano Banana. 6 GPT-Image and Nano Banana models with one key. Fixed price per image by resolution and quality, from ₩12.

Saju Report

— Every Saju interpretation at once. No questions, one tap — a Markdown report by section, from the overview to wealth, love and 10-year luck cycles, in one shot. A one-shot API built for single-purchase products priced at 990 KRW.

YouTube summary

— Video summaries and Q&A from one link. Give it a YouTube link and it extracts the captions and returns a summary with timestamp links, or Q&A grounded in the video. Also usable as opt-in context for chat and readings.

Prices are on the pricing page; requests and responses are in the docs.
