about_tandiu_data | What data TANDIU publishes, refresh cadence, price basis and how to cite. Call first. params: none |
list_llm_prices | Official API list prices (USD per 1M tokens) with Artificial Analysis, LiveBench 2.0 and Epoch AI scores for major US and Chinese LLMs. Filter and sort. params: country, vendor, query, sort_by, limit |
cheapest_model_for_score | Cheapest models whose benchmark score meets a threshold (absolute or percent of the best score). params: metric, min_score, min_percent_of_top, country, limit |
get_price_index | Chain-linked LLM price index (CN, US or all models), 30-day change, median price and series. params: group, since |
get_llm_price_history | Pro (API key required): daily official list-price history per model since July 2026, USD and RMB per 1M tokens, with source URLs. Filter by model, vendor, country and date range. params: model, vendor, country, since, until, limit |
list_price_changes | Official list-price cuts/increases observed in daily snapshots, and models newly added to tracking. params: since, min_change_pct, limit |
estimate_self_hosting | VRAM, GPUs needed, single-stream and batched throughput, hardware cost and the vendor's official API price/speed for self-hosting an open-weights model. Omit model to list available models. params: model, gpus |
list_gpu_prices | Data-center, workstation and consumer GPUs (B300/B200/H200/H100/H20, Ascend 910B/910C, RTX PRO 6000/5500/5000, RTX 5090/5090D/4090D, L40S/L20): VRAM, bandwidth, FP16 compute, list price, China market price (SXM GPUs per 8-GPU node), cloud rental with 7-day change and daily median history (since 2026-10-18; few_samples flags thin markets), sources and dates. params: query, china_available_only, with_cloud_rental |

estimate_enterprise_ai_cost | Monthly AI cost for 10 / 100 / 1,000 / 10,000-person company samples across industries: API (per-role model choice, or the open model's official API) vs self-hosting the same open model on public cloud, private cloud or on-premises GPUs, with GPU count and cost per 1M tokens. params: headcount, query, include_gpu_breakdown, include_team, include_hardware_table |
list_cloud_agents | Cloud agents (one persistent agent per person, team agents, hosting platforms) with specs and monthly prices. params: kind, query, limit |

Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
