Canonical database

All pricing data lives in the repository under database/, normalized from OpenRouter and LiteLLM and refreshed every six hours by the sync service. The SDKs, the CLI, the dashboard, and the notifier all read from these files — there is no separate backend.

Layout

Path	Content
database/current/prices.json	The canonical model catalog with current prices
database/history/prices-<timestamp>.json	Immutable snapshots, one per sync
database/changelog/latest.json	Diff summary of the most recent sync window
database/current/openrouter.json / litellm.json	Raw upstream payloads from the last sync

Model types

model_type follows the OpenRouter output-modality taxonomy:

Type	Meaning
text	Chat / completion language models
image	Image generation and editing
embeddings	Vector embedding models
audio	General audio models
video	Video generation
rerank	Search-result reranking
speech	Text-to-speech
transcription	Speech-to-text

category is an editorial tier: budget, standard, or flagship.

Changelog

database/changelog/latest.json summarizes the latest sync window with per-model change entries typed as model_added, model_removed, pricing_changed, or cache_price_changed — the same events the notifier delivers to webhooks, and what the dashboard's Changelog tab renders.

Browsing

The live dashboard provides a sortable explorer over the full catalog, two-model comparison, a cost calculator, price history charts built from the snapshots, and the changelog.
