Tools of Lantern Works GPU Prices: daily GPU rental price comparison
	Description		Read-only	Idempotent	Open world

`compare_gpu_prices`Compare tracked GPU rental prices for one model (e.g. 'H100', 'A100 SXM', 'RTX 4090', 'L40S'), cheapest first. If a result looks wrong, give the user its report_issue_url. Same data as https://thelanternworks.com/api/v1/gpu-prices.json. Sorted by hourly_usd ascending; each result has source_url and checked_at. 'Cheapest' means cheapest among tracked providers, not the whole market. limit 1-25. Unknown model returns not_found listing tracked models. H100/A100: cheapest_by_form_factor gives one pick per form_factor (tier_class, interruptible, in_stock); same rule as the site. 'NVLink' rows are form 'not stated': NVLink is the bridge, and the vendor doesn't say SXM or PCIe. Each result has tier_class: on-demand \| community \| marketplace \| interruptible (spot/preemptible) \| reserved \| dedicated-monthly. Reserved (reservation/commitment 'starting from') rates are left out unless include_reserved=true, and even then they are never reported as cheapest. DEFAULT on_demand_only=true: results[0] is the cheapest on-demand rate. Pass on_demand_only=false to include spot/interruptible, community and marketplace capacity (each such row is labelled by tier_class and interruptible); the summary then names the cheapest on-demand rate when the overall cheapest isn't. If a model has no on-demand rate, or every on-demand rate needs more GPUs than requested, the default falls back to all rates and says so in on_demand_fallback. gpus (optional, 1-1024; default 1, stated in assumptions): the GPU count you need. A rate ranks only when its min_gpus (smallest allocation sold) is <= gpus; rates sold only as larger allocations (e.g. 8-GPU nodes) are NOT ranked and are listed in excluded_min_gpus (vendor, gpu, tier, min_gpus, gpu_count, hourly_usd, rate_id, source_url, checked_at, reason, min_bill_usd_per_hour, min_bill_basis); min_gpus_unmet counts them (also in brief). Pass gpus=8 to compare 8-GPU nodes. If every rate needs more GPUs, the error says which gpus value ranks them.

`estimate_job_cost`Cost of one GPU job (not cost per hour) among tracked providers, cheapest current compute subtotal first. gpu_family (e.g. 'H100', 'A100 80GB') or its alias gpu (same name compare_gpu_prices uses) is required; if both are given they must match, else invalid_argument. gpus_per_job defaults to 1. Ranking matches compare_gpu_prices' default: fresh rows first (a degraded price, older than 48 h, is shown and flagged but never ranked first while a fresh one exists), fresh on-demand before community/marketplace rows, then compute subtotal ascending; the summary names any cheaper fresh rate ranked lower. If no fresh price exists, stale_fallback=true and the summary says the top row is not a current price. You supply the duration: job_hours, OR work_units plus throughput_units_per_gpu_hour from your own benchmark (job_hours = work_units / (throughput x gpus_per_job)). If you give workload + work_units but no throughput, a directly applicable published figure (closed-division MLPerf Inference, exact GPU variant, inference only) is used: throughput_basis='published_benchmark' with throughput_source {url, quote, date, benchmark, derived, caveats}; your throughput always wins. Otherwise not_found 'missing: throughput for {gpu}'. Whole-instance billing: instances = ceil(gpus_per_job / gpus_per_instance), all allocated GPUs billed (9 GPUs on an 8-GPU-only offer bill 16). Reserved and held-stale rates are never ranked; spot/interruptible only if allow_interruptible. Each result has rate_id, source_url, verified_at, data_age_hours/degraded/stale.

`get_price_changes`GPU rental price changes among tracked providers, each with old/new hourly price, change_pct, direction, the vendor source_url, a stable event_id (dedupe key) and rate_id. Marketplace median moves also have composition_flag (composition, price, mixed, unknown, or null) from successive median, minimum and listing count; composition, mixed and unknown are not price moves. since: 'YYYY-MM-DD' returns every change on or after that date, newest first (daily snapshots in /api/v1/gpu-prices/history.json); omitted returns the latest day's moves (/api/v1/gpu-price-changes.json). cursor: pass next_cursor from a previous call to get every change after it, oldest first, with has_more; loop until has_more is false, and store next_cursor only after processing (a watcher never misses or repeats events). error cursor_expired means re-sync with since and dedupe by event_id. kinds: optional subset of down, up, new, removed, same. gpu: optional model filter (substring, e.g. 'H100'). limit 1-200. Includes data_checked_at and next_refresh_utc (prices refresh daily at about 10:23 UTC).

`optimize_agent_stack`Estimate a monthly stack cost from a short description of the agent being built. description: free text, e.g. 'scrapes 20k JS pages/month via 5 GB residential proxies, 3k search queries, summarizes with an LLM, budget $300/mo'. Parsed deterministically (keywords/regex, no LLM) into components: gpu, scraping, proxy, search, llm_api, email, hosting, database, monitoring. Optional fields override the parse: gpu_hours (GPU-hours/month), gpu_model ('H100', 'A100', 'RTX 4090'), model_size_b (billions of params; sets a minimum VRAM using FP16 x 1.2), scrape_pages, js_rendering, proxy_gb, search_queries, emails_sent, llm_api, monthly_budget_usd. Each component gets the cheapest option with a cited price among tracked providers, with calc, source_url, verified_at, referral_disclosure (set when the link is a referral link) and manual-signup notes. Components with no cited price say 'no sourced price tracked' (nothing is estimated). Totals show the math and say whether they are complete. Pulled listings are excluded. Every option has data_age_hours, degraded (> 48 h) and stale (> 7 days); GPU prices older than 168 h never rank by default (listed in the line's stale_prices); max_data_age_hours replaces that default and drops older options (excluded_too_old counts them). Same data as optimize_stack, compare_gpu_prices and the deal feed.

Each line has the chosen plan, monthly_cost_usd, calc, vendor quote, source_url, checked_at and assumptions, plus alternatives. A vendor price that isn't published is 'unknown' (never estimated). manual_signup_only=true means a human must sign up (never automate it); exclude_manual_signup=true drops those plans.

Only ELIGIBLE rates match (same contract as compare/estimate): every word of gpu must match the model; 'A100 80GB' or vram_gb=80 never matches a 40GB row; tiers (on-demand, community, marketplace, interruptible/spot, dedicated-monthly, reserved; default all but reserved) never matches another class; a row confirmed sold out never matches (in_stock='require' also skips unknown stock). region: code from availability.available_regions; a rate with no unexpired region evidence stays unresolved and never matches.
