This is a conservative upper bound designed to prevent cost overruns — the actual cost will be at or below this figure. May include per-step cost breakdowns and a total ceiling value.","failureModes":["Malformed or empty execution plan schema returns a validation error","Plan with undefined or unsupported cost dimensions may yield incomplete estimates","Overly complex or deeply nested plans may time out","Missing pricing context for certain tools or APIs could result in partial estimates","Network errors or payment failure (x402) prevent the response from being returned"],"whenToPreferThis":"Choose this endpoint when an AI agent needs a hard, fail-closed upper bound on execution costs before committing to a plan — especially in autonomous or multi-step workflows where overspending is a risk. Prefer it over general-purpose cost calculators when you need a conservative maximum (not an average or estimate) specifically for agent execution plans. Particularly valuable in agentic pipelines where intermediate steps have variable costs or where budget approval gates are required before execution.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-20T00:33:29.613Z","isFirstParty":false,"canonicalSlug":"execution-cost-estimator-5935e968"}
