voicegw export-costs

Export per-request cost line items for a date window in CSV or JSON. One row per recorded request: open it in a spreadsheet, or feed it into voicegw reconcile as the VoiceGateway side of a reconciliation. The full workflow is at Cost reconciliation.

Usage

voicegw export-costs --start <YYYY-MM-DD> --end <YYYY-MM-DD> [OPTIONS]

Options

Flag	Short	Type	Default	Description
`--start`		string	required	Start date `YYYY-MM-DD`, UTC, inclusive.
`--end`		string	required	End date `YYYY-MM-DD`, UTC, inclusive.
`--project`	`-p`	string	`null`	Optional project filter.
`--format`	`-f`	string	`csv`	`csv` or `json`.
`--output`	`-o`	string	`-`	Output path; `-` writes to stdout.
`--config`	`-c`	string	`null`	Path to `voicegw.yaml`. Auto-discovered if omitted.

--end is inclusive of the whole day (advanced one day internally for the exclusive upper bound). The storage backend must be enabled (cost_tracking.enabled: true, or VOICEGW_DB_PATH/VOICEGW_DB_URL); otherwise the command prints an error and exits 1.

Output columns

Both formats share this 10-column schema, rows ordered by timestamp ascending:

Column	Notes
`timestamp`	ISO-8601 UTC, e.g. `2026-04-15T09:30:00+00:00`.
`project`	Project id.
`modality`	`stt`, `llm`, or `tts`.
`provider`	e.g. `openai`, `deepgram`, `cartesia`.
`model`	Full `provider/model` string.
`input_units`	Tokens (LLM input), minutes (STT), or characters (TTS).
`output_units`	Tokens (LLM output); `0` for STT/TTS.
`calculated_cost_usd`	Fixed-point USD string, priced through `voice-prices`.
`pricing_source`	`voice-prices@<version>` for cloud models, `voicegateway-local` for `local/`/`ollama/`, empty for unknown.
`status`	`ok` or an error tag.

--format json writes JSONL (one object per line, no outer array).
