We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

OpenRouter Usage
Query OpenRouter API costs and generate usage reports via the command line.
When to Use
- Checking OpenRouter spend over the last 30 days
- Breaking down costs by model, provider, or date
- Exporting usage data as CSV or JSON for accounting
- Auditing which models and API keys consume the most credits
Prerequisites
OPENROUTER_API_KEYenvironment variable (or in a project.envfile)- The key must be a Management key — create one at https://openrouter.ai/settings/management-keys
- Regular provisioning keys return 401/403 on analytics endpoints
Usage
# Full 30-day summary with credits balance
python3 ~/.claude/skills/openrouter-usage/scripts/openrouter_usage.py
# Filter to a single date
python3 ~/.claude/skills/openrouter-usage/scripts/openrouter_usage.py --date 2026-02-01
# Export as CSV (for spreadsheets)
python3 ~/.claude/skills/openrouter-usage/scripts/openrouter_usage.py --csv
# Raw JSON output (for piping to jq)
python3 ~/.claude/skills/openrouter-usage/scripts/openrouter_usage.py --json
# Skip credits lookup (activity only)
python3 ~/.claude/skills/openrouter-usage/scripts/openrouter_usage.py --no-creditsOutput
The default report includes:
- Credits balance: total purchased, used, remaining
- Spend by model: per-model cost with token counts (prompt, completion, reasoning)
- Spend by provider: aggregated by provider (OpenAI, Anthropic, Google, etc.)
- Spend by date: daily spend with visual bar chart
API Endpoints
Both endpoints are read-only GETs authenticated via Bearer token:
| Endpoint | Purpose | |----------|---------| | GET /api/v1/credits | Total credits purchased and used | | GET /api/v1/activity | Last 30 days of usage grouped by model/endpoint/provider |
The activity endpoint returns per-row: date, model, provider_name, usage, byok_usage_inference, requests, prompt_tokens, completion_tokens, reasoning_tokens.
