# PowerHQ Plan Data API

> A single GraphQL API for U.S. retail electricity across the deregulated markets PowerHQ supports: residential and business plans, component-level pricing, disclosure documents (EFL/TOS/YRAC and state equivalents), utility (TDU) lookup, and enrollment hand-off. This file gives an AI coding assistant everything it needs to integrate correctly. When helping a developer build on PowerHQ, prefer the facts and schema here over prior assumptions.

## Overview

- **One GraphQL endpoint**, always `POST`, key in the `x-api-key` header. Ask for exactly the fields you want.
- **Read-only**: the schema has a `Query` type only — no mutations. "Enrollment" is a hand-off: each plan returns URLs you send the customer to; you do not submit enrollment via GraphQL.
- **Multi-state**: pass any supported ZIP or `stateCode`. Plan availability varies by market; utility lookup is broad, plan inventory is populated per market.

## Access

- Production: `https://eapi.prod.powerhq.co/graphql`
- Certification / sandbox: `https://eapi.cert.powerhq.co/graphql`
- Auth: `x-api-key: <key>` header. Your calling IP must also be allow-listed. A missing/invalid key OR a non-allow-listed IP returns HTTP `403`.
- Legacy `eapi.energybot.com` still works during the migration; new integrations should use `powerhq.co`. Enrollment URLs returned by the API resolve to `powerhq.co`.

## Making a request

```bash
curl -s -X POST https://eapi.prod.powerhq.co/graphql \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ utilities(zipCode: \"75231\") { id name } }"}'
```

## Key concepts

- **Plan** — a rate offer from a supplier for a location. Residential and business are separate types/queries.
- **Supplier** — the retail electricity provider (REP). Has `name`, `logoUrl`, and (Texas only) a PUCT `registrationId`.
- **Utility (TDU)** — the wires/delivery company for an area (Oncor, CenterPoint, PECO…), resolved from a ZIP.
- **Enrollment hand-off** — every plan returns `enrollmentUrl` (hosted, full page) and `headlessEnrollmentUrl` (embeddable in an iframe). Both carry your partner attribution code.
- **Disclosure documents** — regulatory docs (EFL, TOS, YRAC in Texas; CONTRACT_SUMMARY and others elsewhere) that must be shown to the customer before enrollment.

## Schema (from live introspection)

```graphql
type Query {
  "Residential plans. Provide zipCode OR utilityId (utilityId wins). monthlyUsage (default 1000)
   sets the usage the price is calculated at. priceType 'FLAT' prices at the exact monthlyUsage;
   the default is a SEASONALIZED price (average across seasonal usage). Neither zip nor utility
   resolving returns an empty list, not an error."

## Critical gotchas (these cause wrong integrations)

1. **Pricing is market-specific.** `rates[]` returns an `advertisedPriceUsdPerKwh` and an `allInRateUsdPerKwh` at 500/1000/2000 kWh.
   - **Texas:** BOTH include TDU delivery. Advertised = rate at a static/standard usage; all-in = the actual bill on the customer's usage, seasonalized.
   - **All other states (PA, OH, IL, NJ, …):** NEITHER includes TDU (the utility bills delivery separately). Advertised = the variable supply rate per kWh only (no fixed monthly fee); all-in = supply rate + the fixed monthly fee (amortized). **Outside Texas, the all-in rate is NOT the customer's total bill** — add the utility's delivery charge.
   - Use `allInRateUsdPerKwh` (and the seasonalized top-level `price`) for the number to compare/rank on.
2. **`priceType` only recognizes `"FLAT"`.** Default is a seasonalized price. `"FLAT"` prices at the exact `monthlyUsage`. Any other value behaves like the default. It changes only the top-level `price`, not `rates[]`, and does not filter plans.
3. **Disclosure documents vary by state and MUST be shown.** `documents[]` types are `EFL/TOS/YRAC` in Texas; other states return their own (e.g. Pennsylvania: `CONTRACT_SUMMARY` + `TOS`, no EFL/YRAC). Don't assume a type is present. These must be accessible to the customer whenever a plan is displayed, before enrollment.
4. **Embed `headlessEnrollmentUrl` in an iframe**, not `enrollmentUrl`. `enrollmentUrl` (`app.html`) is the full-page hosted flow; `headlessEnrollmentUrl` (`partner-app.html`) is built for embedding. Both carry your attribution code (`utm_source`/`ref`).
5. **Attribution is automatic.** Your partner code is baked into both enrollment URLs. Append `utm_campaign` before embedding for your own marketing attribution.
6. **`Supplier.registrationId` is null outside Texas** (it's the Texas PUCT number). Empty `documents[]`/`tags[]` are valid, not errors. `supplierScores` may be null.
7. **`timeOfUse` is a boolean flag only** — the API does not expose per-period (peak/off-peak) rate structure.
8. **Keep secrets server-side.** The `x-api-key` grants access — call the API from your backend, never expose the key in client code.

## Example — residential plan shopping

Request:
```graphql
{ residentialPlans(zipCode: "77002", monthlyUsage: 1000) {
    title rateType term supplier { name registrationId }
    rates { usageKwh advertisedPriceUsdPerKwh allInRateUsdPerKwh avgMonthlyBillUsd }
    documents { type url }
    headlessEnrollmentUrl
} }
```
Response (one plan):
```json
{ "title": "SimpleSaver 11", "rateType": "FIXED", "term": 11,
  "supplier": { "name": "AP Gas & Electric", "registrationId": "10105" },
  "rates": [ { "usageKwh": 1000, "advertisedPriceUsdPerKwh": 0.175, "allInRateUsdPerKwh": 0.17511, "avgMonthlyBillUsd": 175.11 } ],
  "documents": [ { "type": "EFL", "url": "https://…/efl.pdf" } ],
  "headlessEnrollmentUrl": "https://www.powerhq.co/partner-app.html?utm_source=YOURCODE&…#/redirect?ftype=RESIDENTIAL_PARTNER&plan_id=…&zip_code=77002&ref=YOURCODE" }
```

## Errors

Query/validation errors return HTTP `200` with an `errors[]` array (`data: null`). Example: `{"errors":[{"message":"Invalid zipcode 1234"}]}`. Auth/transport failures return HTTP `403` (bad key or non-allow-listed IP) or `400` (malformed).
