- Pick models with strong tool calling for agent work and check their error rate on /rankings.
Every tool call is logged with its arguments and latency in the Requesty dashboard.

Method and definitions
- Tool names come from the tool calls in model responses, lowercased. A tool counts once per request even if it is called several times.
- A tool name needs 10 or more organizations before it is listed, on top of the standard floors, so names specific to one company never appear.
- Tool-call data is recorded from July 2026, so this series starts then.
- A row is published only when it has at least 20 requests, at least 5 distinct organizations, and no single organization above 80% of its traffic. These are the same floors /rankings uses. Rows below the floors are withheld, not estimated.
- Only shares, rates, medians and organization bands are published. Absolute request, token and spend totals stay private.
- Reach:
- Organizations whose requests called this tool, divided by organizations with any tool call in the month.
- Tool-call request:
- A chat request whose response contained at least one tool call.
Caveats
- Different agents name the same tool differently (read vs read_file, bash vs shell vs terminal). Names are not merged.
- Only tool calls the model returned are counted, not tools that were offered but unused.
