🟢search_skus(query, category, provider, limit, listing)
Find VPS plans, GPU instances or LLM models by name/id substring, category (vps|gpu|llm) and provider. Active SKUs on the provider's public price page or product API by default (listing filter). Returns each match's current list price, listing_status, unit and currency, verified_at, stale flag and source_url. Read-only; reads the ledger's own daily archive, nothing is fetched live.

}🟢get_price(sku_id)
Current list price of one SKU (id like vps/ovhcloud/vps-2027-model2 or llm/anthropic/claude-sonnet-5-5) with all secondary prices, USD/EUR equivalents, spec, source URL, verified_at, a stale flag that is true when the source's latest fetch failed (the price shown is then the last verified one), and other listings of the same model. Returns an error object for an unknown id.

Price change points of a SKU over the last N days (default 90): each row is when a price started to hold, with USD/EUR and the FX rate used. Rows are change points, not daily samples. Returns an error object for an unknown id.

}🟢cheapest_for_spec(category, vcpu, ram_gb, disk_gb, gpu, ...)
Cheapest active SKUs meeting a minimum spec, ranked by list price only (no sponsorship, no affiliate weighting). category vps|gpu|llm; vcpu, ram_gb, disk_gb minimums; gpu model substring (e.g. H100); region 'eu' for EU-deployable; currency USD|EUR for the ranking. Each row carries verified_at, stale and source_url.

}🟢estimate_cost(sku_id, input_tokens, output_tokens, cached_input_tokens, hours, ...)
Itemised cost of a usage profile at the SKU's current list price: tokens (input/output/cached) for LLM SKUs, hours/months for instances. Returns line items with the rates used, native, USD and EUR totals, verified_at and source_url. Pure arithmetic on stored prices; excl. VAT unless the result says otherwise.
