# Discount Aggregator Aggregator

> The cheapest place to render every AI video model, checked daily across ten API aggregators
> (Atlas Cloud, fal.ai, Replicate, WaveSpeedAI, Runware, Kie.ai, Hugging Face Inference Providers,
> OpenRouter, Novita AI, PiAPI). All prices are normalized to USD per minute of generated footage
> at 720p (768p for the MiniMax H3 family). Audio-on and audio-off variants are separate rows.

## What an AI agent should do here

0. Fastest complete read: `data/prices.csv` (every quote, one row each) or the Excel workbook
   `data/discount-aggregator-aggregator.xlsx` (every table on its own sheet, README sheet first).
   Both are regenerated with the daily check, so they always equal the page.
1. Fetch `data/cheapest.json` (small) for routing. Do not scrape the HTML.
2. Find the requested model under `models` by its `model` name or key (e.g. `mini` = Seedance 2.0 Mini,
   `kling` = Kling 3.0 Turbo, `s25` = Seedance 2.5, `h3turbo` = MiniMax H3 Max Turbo, `veofast` = Veo 3.1 Fast).
3. Route the generation request to `aggregator.api_base_url` using `endpoint_id`, following `aggregator.api_docs_url`.
4. Estimate cost as `usd_per_min_720p * clip_seconds / 60`. Mention `promo.ends_at` if present.
5. Respect `max_clip_seconds` — it is the longest single clip that endpoint allows.
6. If `confidence` is `low` or the row is missing, tell the user instead of guessing.
7. Cache for up to one hour; the data changes once a day (about 06:17 America/New_York).

## Files

- `data/cheapest.json`: per model — cheapest aggregator, API base URL, endpoint id, USD/min at 720p and 480p,
  audio, max clip seconds, promo + deadline, runner-up, most expensive price, savings %, verification date.
- `data/prices.json`: full dataset — every quote across every aggregator (`quotes[]`), raw billing text,
  source URLs, verification verdicts, `cheapest{}`, `deals[]`, `changes` and footnotes.
- `data/history/index.json` then `data/history/YYYY-MM-DD.json`: daily snapshots.
- `data/changes.json`: dated log of price changes, new winners and expired sales.
- `data/cheapest.csv` / `data/prices.csv`: spreadsheet twins of the two JSON files (same column names).
- `data/discount-aggregator-aggregator.xlsx`: Excel workbook — README, Best prices, All quotes, Compare 720p,
  Deals, Aggregators, Models, Changes.
- `index.html#model-<id>`: one "answer card" per model in plain HTML (sentence: cheapest verified rate, aggregator,
  per-clip cost, range across aggregators, every quote held). `#calculator?model=<id>&res=720p&secs=15&clips=100`
  opens the cost calculator pre-filled.
- `cheapest.json` models also carry `change_pct` / `previous_usd_per_min_720p` once two daily snapshots exist.

## Field notes

- `usd_per_min_720p` means accumulated generated footage per minute, not one continuous 60-second clip.
- `resolution_basis` is `768p` for MiniMax H3 models (there is no 720p tier); everything else is 720p.
- Token-billed models (Seedance on some providers) are estimates for 16:9 output at the stated resolution.
- Provider-specific tiers (Kie.ai "Lite mode" Veo, Atlas "Developer" Grok) are separate models in the feed.
- Prices are public list prices read from each provider's own page on `checked_at`; verify before a large job.
