Capabilities

Tools 9

calculate_tco

Total cost of ownership for a product and team size: sourced line items (licenses with price escalation, benchmark implementation), year-one + multi-year totals, effective per-seat cost. The defensible "true cost for an N-person team" answer.

Discovered
compare_software

Side-by-side pricing comparison of 2–4 products (starting price, enterprise tier, median annual cost, free tier, ratings).

Discovered
discover_software

Find software products by name search or criteria (category, max price, free tier). Returns matching slugs to look up — use "query" to find the slug for a product name.

Discovered
estimate_llm_cost

Estimate the cost of an LLM/API workload (input + output tokens) for a usage-priced provider (OpenAI, Anthropic, AWS Bedrock…) from its real rate card.

Discovered
get_hidden_costs

The documented hidden/implementation/add-on costs of a product (uplifts, onboarding fees, overages), each with a sourced quote + date. The "what they don't tell you" answer.

Discovered
get_negotiation_tips

Sourced negotiation tactics for a product with success-likelihood (how to get a discount).

Discovered
get_price_changes

Recent software pricing changes CostBench detected against vendor pricing pages (increases, decreases, plan restructures) — dated, with before/after price bands and a source link. Filter by product slug, category, or lookback window. The "what changed lately" answer; each item links to the sourced record.

Discovered
get_price_history

Dated per-quarter snapshots of a product's pricing page. Returns observations, NOT a trend figure — CostBench does not publish one, because diffing snapshots across renamed/restructured plan lineups is ~90% measurement artifact.

Discovered
get_pricing

Full sourced pricing record for a software product: tiers, hidden costs, contract terms, market data, sentiment, negotiation tips, TCO scenarios, price history — every claim with its sources + a confidence/verification envelope.
