| Path | Purpose |
|------|---------|

| `https://www.pacardexchange.com/` | Marketing home |
| `https://www.pacardexchange.com/seller-prices` | Lowest sealed-box JPY offers per set from tracked **active** sellers; compares to TCGplayer reference when available |
| `https://www.pacardexchange.com/seller-prices/llms.txt` | **LLM-oriented Markdown** for this area: JSON API (`/api/public/seller-prices/daily`), field semantics, links to UI + site-wide `llms.txt` |
| `https://www.pacardexchange.com/sellers` | Discover active sellers (sort by reviews, followers, or lowest prices) |
| `https://www.pacardexchange.com/sellers/{instagramHandle}` | Public seller profile (reviews, ordering info, prices when snapshot exists) |
| `https://www.pacardexchange.com/sellers/{instagramHandle}/llms.txt` | **Per-seller Markdown:** identity, reviews, payment/price-list flags, ordering guide; **plus a table of sealed-box JPY offers** for sets where this seller is in the **top-three** lowest offers on the current Pacific snapshot (same rule as the HTML profile; large lists cap at 250 rows) |
| `https://www.pacardexchange.com/seller-prices/{tcgdexId}` | Per-set price history chart, offers table, snapshot date |

Date keys are **YYYY-MM-DD** aligned to **America/Los_Angeles** (“Pacific”) for snapshot selection. If a requested calendar day has no qualifying seller snapshots, the API may return data for the **latest prior** date with data (`usedFallbackDate: true`).

## Public JSON (no auth)

| Method | URL | Notes |
|--------|-----|-------|
| GET | `https://www.pacardexchange.com/api/public/seller-prices/daily?date=YYYY-MM-DD` | Optional `date`. Response includes `dateKeyRequested`, `dateKeyUsed`, `usedFallbackDate`, `cards` (sets, lowest offers, TCGplayer ref). |
| GET | `https://www.pacardexchange.com/api/public/sellers` | `{ sellers: [...] }` — active sellers for pickers/search. |
| GET | `https://www.pacardexchange.com/api/public/pokemon-sets` | `{ sets: [...] }` — catalog sets (capped list for UI/sitemap). |
| GET | `https://www.pacardexchange.com/api/public/seller-reviews/stream?limit=&sellerHandle=&tcgdexId=&ratings=&cursorCreatedAt=&cursorId=` | Paginated published reviews (cursor params optional). |
| POST | `https://www.pacardexchange.com/api/public/agent-visit-feedback` | **Automated agents:** submit visit report after your task (`visitIntent`, `helpfulForTask`, optional `comment`, `primaryPath`). See `/agents.md`. |

## Limitations (do not over-claim)

- “Daily” refers to **our ingestion snapshot** per Pacific date key, not every seller updating every calendar day.
- FX / USD→JPY for TCGplayer display uses a **site-configured rate** (indicative).
- Not all sets or sellers appear on every date; empty `cards` means no qualifying snapshot for that request.

## Trends and history

- **Per-set page** (`/seller-prices/{tcgdexId}`): charts combine **seller snapshot history** and **TCGplayer CSV snapshot** points over a bounded window. Interpret charts as “what our pipeline stored for that date key,” not a guarantee of intraday market moves.
- **Daily board** (`/api/public/seller-prices/daily`): for each set card, **offers** are the lowest **sealed-box JPY** rows from **active** sellers for `dateKeyUsed` (top offers after aggregation). **tcgplayerReference** is derived from stored TCGCSV/TCGplayer-compatible snapshots plus USD→JPY conversion.

## Response sketch: daily seller prices API

Returns JSON merging:

- `message`: human-readable status string
- `dateKeyRequested`: Pacific calendar key requested (typically “today” Pacific when `date` omitted)
- `dateKeyUsed`: snapshot date actually used (may be earlier if no data on requested day)
- `usedFallbackDate`: boolean — true when `dateKeyUsed !== dateKeyRequested`
- `cards`: array of set-level rows; each includes Pokémon set metadata, `offers` (seller id/handle, **priceJPY**, ratings), `tcgplayerReference` (USD/JPY fields, `dateKey`, `fetchedAt`), and optional product URLs

Exact field names and nested shapes match the TypeScript types in the codebase (`DailySellerPriceBoardPayload`, `DailySellerPriceCardPayload`).

## Response sketch: sellers API

- `sellers`: array of active seller options (instagram handle, display name, image URL, etc.) for public UI consumption.

## Response sketch: pokemon-sets API

- `sets`: array of public set metadata (`tcgdexId`, names, release-oriented fields as exposed by the catalog).

## Response sketch: seller reviews stream

- Paginated **published** reviews; supports filtering by seller handle, `tcgdexId`, star `ratings`, and cursor pagination. Default and max `limit` enforced server-side.
