experiment_estimate
Pack: ai-model-experiments · Endpoint: https://gateway.pipeworx.io/ai-model-experiments/mcp
Dry-run cost estimate for an experiment BEFORE creating it — cell count and estimated billed cost range (at our 1.5× pricing) for prompts × models × reps. Free to call, no side effects, does not need credit balance. Same spec shape as experiment_create. Example: experiment_estimate({ prompts: [“Summarize: …”], models: [“anthropic/claude-sonnet-4.5”, “openai/gpt-5”], reps: 2 })
