Available Operations

• GetRankingsDaily - Daily token totals for top 50 models

GetRankingsDaily

Returns the top 50 public models per day by total token usage on OpenRouter, plus a single aggregated other row per day that sums every model outside that top 50. Token totals are prompt_tokens + completion_tokens, matching the public rankings chart on openrouter.ai/rankings.

Each row is a distinct (date, model_permaslug) pair. The other row uses the reserved permaslug other and is always returned last within its date, so callers can compute top-50 traffic / total daily traffic without a second request.

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/rankings), as of {as_of}.”

Token counts come from each upstream provider’s own tokenizer (Anthropic counts are as reported by Anthropic, OpenAI counts are as reported by OpenAI, etc.), so a token in one row is not directly comparable to a token in another row from a different provider.

Example Usage

package main

import(
	"context"
	"os"
	openrouter "github.com/OpenRouterTeam/go-sdk"
	"log"
)

func main() {
    ctx := context.Background()

    s := openrouter.New(
        openrouter.WithSecurity(os.Getenv("OPENROUTER_API_KEY")),
    )

    res, err := s.Datasets.GetRankingsDaily(ctx, nil, nil)
    if err != nil {
        log.Fatal(err)
    }
    if res != nil {
        // handle response
    }
}

Parameters

Parameter	Type	Required	Description	Example
ctx	context.Context	:heavy_check_mark:	The context to use for the request.
startDate	*string	:heavy_minus_sign:	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.	2026-04-12
endDate	*string	:heavy_minus_sign:	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.	2026-05-11
opts	[]operations.Option	:heavy_minus_sign:	The options for this request.

Response

*components.RankingsDailyResponse, error
