Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.
Tools: log_costs cost_report weekly_report usage_and_upgrade
log_costs | Log what your agent's model and tool calls cost, then get the running total for the run and for today. Pass events (one per call, up to 500) or an OpenTelemetry OTLP/JSON trace export as otel (gen_ai.usage.input_tokens / output_tokens / gen_ai.request.model are read; trace id becomes run_id). Give cost_usd per call, or tokens plus your own per-million prices; nothing is guessed. Optional caps: run params: run_id, events, otel, price_in_per_m, price_out_per_m, run_cap_usd, daily_cap_usd, alert_webhook |
cost_report | Cost per run, per tool, per model and per day. Without an API key pass run_id (one run). With a key: everything on that key. Free shows 7 days, Pro 30. params: run_id, days |
weekly_report | Plain-English summary of the last 7 days of spend: total, top runs, top tools, top models, busiest day. Read-only; sends nothing. Needs a free API key. params: none |
usage_and_upgrade | Show today's usage for your key or IP and the $9/month upgrade link. Free tier: 500 calls/day. Not metered. params: none |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json. Opt-out: how or hello@youraitools.co.
