// THE EXCHANGE × THE APIS

The Bus and the APIs walk into a diner.

One orders ham. The other orders eggs. The waiter says "I see you two come in here every day." They say "yeah, we work better together." That's Hunuu Health's data architecture.

// THE EXCHANGE (the bus) // OUR APIs (the order)
// PART 1 · THE BUS

The Exchange is the backbone. The APIs are the order.

The Exchange is our internal data bus. Borrowed straight from telecom: a high-throughput message router that takes signals from every wearable, EHR, satellite, and genomics upload — strips the PII, normalizes the units, runs the TensorFlow models, and shoves the results out to whoever asked for them. It runs on port 7220 with a circuit breaker, an audit log, and an attitude.

Think of The Exchange like a 1970s phone switchboard run by an extremely caffeinated woman with a headset and zero patience for nonsense. Every call, every byte, every glucose reading — it routes them all. It does not care about your feelings. — from the Hunuu engineering values doc, paraphrased

The APIs sit on top. Each one is a service that orders specific data off the bus — wearables, biomarkers, environment, genomics, EHR, AI predictions. You hit an API endpoint, the API calls the bus, the bus routes the request, and you get an answer in under a second. No N+1 queries. No federated nightmares. No "please contact our integrations team."

You can't have a great omelette without great eggs and a great pan. The bus is the pan. The APIs are the eggs. Try cooking eggs without a pan and tell me how that goes. — Matthew, while making breakfast (probably)
// PART 2 · TELECOM ARCHITECTURE

If you've ever built a phone network, this'll feel familiar.

We borrowed the architecture from the telcos. Decades of moving voice and data at scale taught the industry some things, and we shamelessly stole all of it. Here's the dictionary:

Trunk Line
The Exchange's main backbone. Carries every signal between sources and APIs. Built on a Go binary running on port 7220 because we like things fast.
Circuit
A single connection between an API and the bus. Each API endpoint is a circuit. Failing a circuit doesn't take down the trunk — it just takes down that one phone, so to speak.
PBX / Switching
Where The Exchange decides which API gets which data. The agent router with circuit breaker. Falls back to local Llama3 if the upstream is having a bad day.
Tariff
Pricing tier. À la carte, bundle, or unlimited. Yes, we still call it a tariff because we're old-school.
SLA
Service Level Agreement. Bronze tier gets best-effort. Gold gets 99.9% uptime. Enterprise gets a number you can call at 3am to yell at someone (probably Matthew).
Roaming
Cross-region access. Sign up for North America, want to query Europe too? That's roaming. You pay for it. Just like your cell carrier in 2008.
// PART 3 · USE-CASE BUNDLES

Pick your flavor of breakfast.

Sure, you can buy each API à la carte. But most marketers, researchers, and LLM operators want a bundle that solves a specific problem. Here's what we bundle out of the box:

🤧
Allergy Bundle
/environment/pollen + /environment/air + /fhir/allergies + /biomarkers

Pollen forecast + air quality + the user's actual diagnosed allergies + their HRV/sleep when symptoms hit. Personalized severity scoring out of the box.

// for the marketer who thinks "ALLERGY SEASON SALE" is a strategy in 2026 — we'll tell you exactly when and where
🦠
Flu Watch · Worldwide
/environment/air + /biomarkers/anomalies + /siq/regional + CDC FluView

Aggregated biomarker anomalies (RHR spikes, body temp, sleep disruption) across millions of users. Geographic heatmap. The flu is coming. We see it 2 weeks before the CDC does.

// for the marketer who wants to ship Theraflu before the cough — yeah we got you
📍
Flu Watch · Regional
Same as worldwide, scoped to ZIP / DMA / state

Same data. Smaller geography. Cheaper. For the brand that's only running a campaign in Atlanta DMA, you don't need Tokyo.

// because not every brand has Procter & Gamble money. We respect that.
🍩
Metabolic Bundle
/biomarkers/glucose + /devices/cgm + /supplements + /nutrition

CGM streams + diet + supplement tracking. For the GLP-1 era. Brands selling "glucose-friendly" anything will want this. Personalized down to the bite.

// the next decade of food marketing runs on glucose data, fight me
😴
Sleep & Recovery
/biomarkers/sleep + /environment/uv + /biomarkers/hrv + /biomarkers/temp

Sleep architecture, HRV recovery, body temp, environmental disruptors. For mattress brands, magnesium brands, blue-light-glasses brands. And the audience knows the difference.

// fair warning: the people who buy oura rings can smell vaporware from a mile away
🧬
Pharma Research
/genomics + /fhir + /biomarkers + de-identified cohort export

Genotype × phenotype × longitudinal biomarkers. HIPAA-compliant cohort builder. RWE (real-world evidence) data ready for FDA submission packages.

// this one's the enterprise tier or nothing — pharma's gonna pharma
// PART 4 · TARIFFS (we're still calling them tariffs)

Three ways to pay for breakfast.

A la carte. Bundle. Unlimited. We don't do the SaaS-trick where the actually-useful stuff is locked behind "Enterprise — Contact Sales." All prices below are real. No call required to buy a hash brown.

// PART 5 · GET YOUR APRON ON

Onboard yourself in under 5 minutes.

Whether you're a digital marketing platform, an LLM operator, an agency, a researcher, or a brand that just wants better health data — the onboarding is self-serve.

Hop over to command.hunuuhealth.com/onboard — pick your use case, pick your region, pick your tier. We generate the keys, send the docs, and your data starts flowing the moment Stripe clears.

Heads up — we don't make you "schedule a demo with our success team" before you can see pricing. Pricing's right above. The button below works. Click it. We have stuff to do and so do you. — management, lovingly
