Your goal: add up reported charges
- Open Calculator and select Check recorded spending.
- Select a UTF-8
.jsonor.jsonlfile: one OpenRouter response, an array of responses, or one response per line. Generation-metadata responses are also supported. - Read the covered total and warnings. Expand Inspect billing metadata for extracted request IDs and charges.
- Clear records when finished. Explicitly download sanitized billing metadata only if you want a local copy.
Which fields are read?
Responses use id and usage.cost; generation responses use data.id and data.total_cost. Missing charge fields are not zero. Duplicate IDs count once; conflicting IDs are excluded. Native counts, provider, model and tier are retained when supplied. Cumulative CLI counters, arbitrary CSV and subscription-equivalent estimates are not supported formats.
File protections
Files are parsed in a local worker with a five-second timeout, 10 MB limit and at most 10,000 records. Invalid UTF-8, excessive nesting/structure and duplicate JSON keys are rejected. Nothing is uploaded or executed. Prompt/content/account fields are discarded from derived data, and displayed text is escaped. These checks are not antivirus scanning or invoice authentication.
See response usage and generation metadata.
