API ReferenceDatasets

Top apps by token usage

Returns the top public apps on OpenRouter ranked by token usage inside the requested date window, matching the public apps marketplace on openrouter.ai/apps. Token totals are `prompt_tokens + completion_tokens`; hidden and private apps are excluded and traffic from related app aliases is merged into the canonical visible app. `sort=popular` (default) ranks by total token volume inside the window. `sort=trending` ranks by absolute excess token growth: window volume minus the average volume of the three equal-length periods immediately preceding the window. Apps with no excess growth are omitted, so `trending` may return fewer than `limit` rows. Filter with `category` (marketplace category group, e.g. `coding`) or `subcategory` (e.g. `cli-agent`). Ranks are re-numbered 1..N after filtering. Page with `offset` — `rank` stays absolute, so the first row of `offset=50` is `rank: 51`. Authenticate with any valid OpenRouter API key (same key used for inference). Rate-limited to 30 requests/minute per key and 500 requests/day per account. When republishing or quoting this dataset, OpenRouter must be cited as: "Source: OpenRouter (openrouter.ai/apps), as of {as_of}." Token counts come from each upstream provider's own tokenizer, so a token attributed to one app is not directly comparable to a token attributed to another app whose traffic flows through a different provider.

Query parameters

categoryenumOptional

Marketplace category group to filter by (e.g. coding). Only apps tagged with a subcategory inside this group are returned. Mutually combinable with subcategory — when both are supplied the subcategory must belong to the category group.

Allowed values:
subcategoryenumOptional

Marketplace subcategory to filter by (e.g. cli-agent). Takes precedence over category for the actual filter; when category is also supplied the pair must be consistent.

sortenumOptionalDefaults to popular

popular ranks apps by total token volume inside the date window. trending ranks apps by absolute excess token growth: window volume minus the average volume of the three equal-length periods immediately preceding the window. Apps with no excess growth are omitted from trending results.

Allowed values:
start_datestringOptionalformat: "^\d{4}-\d{2}-\d{2}$"

Start of the date window in YYYY-MM-DD (UTC), inclusive. Defaults to 30 days before end_date. The dataset begins at 2025-01-01; earlier values are clamped forward to that floor and the resolved value is echoed in meta.start_date.

end_datestringOptionalformat: "^\d{4}-\d{2}-\d{2}$"

End of the date window in YYYY-MM-DD (UTC), inclusive. Defaults to the most recent completed UTC day. Must be on or after 2025-01-01; earlier values are rejected with a 400.

limitintegerOptional1-100Defaults to 50

Maximum number of apps to return (1-100). Defaults to 50.

offsetintegerOptional0-100Defaults to 0

Number of ranked apps to skip before the first returned row (0-100). Defaults to 0. rank stays absolute, so the first row of offset=50 is rank: 51.

Response

Apps ranked per the requested sort, re-numbered 1..N. popular sorts by total_tokens descending; trending sorts by absolute excess token growth descending and may return fewer than limit rows.

datalist of objects

Apps ranked per the requested sort, re-numbered 1..N after category filtering. popular sorts by total_tokens descending; trending sorts by absolute excess token growth descending and may return fewer than limit rows when few apps are growing.
