# SiliconTicker — complete agent guide Canonical site: https://siliconticker.com Purpose: Independent, source-first intelligence for AI compute markets, public GPU rental prices, compute derivatives, semiconductors, cloud capacity and infrastructure capital. Primary language: en Localized market overviews: https://siliconticker.com/es, https://siliconticker.com/de, https://siliconticker.com/fr, https://siliconticker.com/ja Authentication: none for documented public endpoints OpenAPI: https://siliconticker.com/openapi.json Short guide: https://siliconticker.com/llms.txt Terms: https://siliconticker.com/terms ## Rental comparison Use https://siliconticker.com/compare for filters, whole-plan estimates, and shareable shortlists. https://siliconticker.com/api/compare returns schema_version 1.0 with camelCase catalog fields and per-offer pricingType (on-demand, public-list, spot), sourceUrl, observedAt, status, gpuCount, totalHourlyUsd, and availability=unconfirmed. It is separate from CL-FCR; model enrichment must not be treated as an index-methodology change. Estimates exclude additional fees, caps and discounts, and assume constant displayed rates. Regions are advertised locations, not confirmed available capacity. Saved URLs contain offer IDs and filters, not frozen quotes. ## Retrieval order 1. Start with the relevant human page for definitions and limitations, then retrieve the matching public JSON endpoint for values. 2. Check checked_at, observed_at, freshness_status, source_url and license before using an observation. 3. Cite the canonical URL and upstream source. Do not infer transactions, live availability, executable pricing, investment suitability or a product launch from incomplete evidence. ## Supported public APIs - GET https://siliconticker.com/api/compare — schema 1.0. Comparison catalog with camelCase offer fields, source links, plan costs and pricing types. Availability is unconfirmed. - GET https://siliconticker.com/api/markets — schema 2.0. Normalized public-cloud GPU list prices, provider offers, CL-FCR, history, coverage and provenance. Cached for one hour at the shared edge; the underlying source normally publishes daily. - GET https://siliconticker.com/api/markets/azure-spot — schema 1.0. Official Microsoft Azure H100 and A100 Linux Spot retail tariffs across regions for two representative single-GPU VMs. Cached for one hour. - GET https://siliconticker.com/api/news — schema 2.1. Original SiliconTicker analysis and first-party NVIDIA, AMD and AWS releases. Intel and Google Cloud are editorial references, not connected feeds. Cached for one hour. - GET https://siliconticker.com/api/sources — schema 2.0. Source rights, status, cadence and coverage registry. - GET https://siliconticker.com/api/health — schema 2.0. Current connector health and independent checked, observed and source-generated clocks. All supported APIs return JSON, allow cross-origin GET requests and provide absolute self or discovery URLs. The internal https://siliconticker.com/api/markets/client route is not a public contract. ## Market semantics - value is the published numeric value; display_value is presentation text. - observed_at is when the represented upstream snapshot was observed. checked_at is when SiliconTicker most recently checked the connector. source_generated_at is the upstream snapshot timestamp when supplied. - freshness_status describes whether the response is fresh, stale or a fallback. A successful HTTP response does not by itself mean that the underlying observation is new. - quotes summarize eligible normalized list-price offers by GPU family. They are not transactions, bids, executable offers or investment products. - offers contain plan totals and per-GPU normalization. Multi-GPU plan totals are divided by the reported GPU count. - coverage distinguishes upstream source plan totals from rows with enough information to normalize. ## Azure Spot semantics - market_type is capacity_contingent_spot_retail. These values are vendor tariffs, not a guaranteed fill, transaction, bid, executable quote or proof of available capacity. - tradeable is false and availability_guaranteed is false. Azure Spot VMs remain subject to regional capacity, quota and interruption. - observed_at is when SiliconTicker queried the public API. effective_start_date is when Microsoft says that regional tariff became effective; it is not the quote-observation clock. - total_vm_hourly_usd is the published VM-hour retail price. per_gpu_hourly_usd divides that value by the GPU count in Microsoft VM specifications. - Current coverage is Standard_NC40ads_H100_v5 (one H100 NVL 94GB) and Standard_NC24ads_A100_v4 (one A100 PCIe 80GB). It is a representative tape, not the complete Azure GPU catalog. - Microsoft states that net-new capacity is currently being deployed only for NCads H100 v5. Preserve capacity_note: the A100 tariff may represent legacy, capacity-constrained supply and does not establish availability. - Windows, Dev/Test, Low Priority, reservation and non-Spot rows are excluded. Preserve the exact SKU, region, price, clocks and limitation fields when citing this feed. ## Brand and API compatibility SiliconTicker is the publisher. Cite https://siliconticker.com URLs. Owned production aliases permanently redirect to this origin with paths and queries preserved. The CL-FCR symbol and /indices/cl-fcr route are stable identifiers, not a separate publisher. The index methodology and history are unchanged by the rebrand. Prefer update_policy.check_cadence and the X-Data-Freshness header. The previous branded cadence field and freshness header remain deprecated aliases for schema 2.0 clients. News records now expose publisher="SiliconTicker" and content_type="original_analysis"; the legacy type discriminator is retained for schema 2.1 clients. ## CL-FCR index CL-FCR is the Frontier Compute Rate: the current-snapshot median of every eligible normalized H100-family, H200, MI300X and B300 public-cloud offer in the licensed GPU Cloud Compare snapshot. Its unit is USD per GPU-hour. Preserve symbol, value, unit, observed_at, source_url, coverage_status, provider_count, offer_count and tradeable=false when citing it. CL-FCR is not tradeable, transaction-based, investable, executable or a derivative settlement value. It is a transparent reference index, not a regulated financial benchmark. Full methodology: https://siliconticker.com/methodology#index ## News semantics - editorial contains original SiliconTicker analysis and a canonical_url. - official_signals contains first-party source releases. publication_recency describes article age; source_retrieval_status describes connector retrieval. - source_health is operational metadata, not editorial recency. - Planned CME and ICE/ORNN products must remain described as planned or pending until the relevant venue confirms launch. - CME's September 28, 2026 notice postponed its compute futures launch pending regulatory review. See https://siliconticker.com/news/cme-compute-futures (updated October 7, 2026) and the dated official_source_url in the market roadmap. A historical target date is not launch confirmation. ## Citation contract For market data, cite “SiliconTicker”, the canonical API or page URL, the upstream attribution and license, and preserve the value, unit, observed_at, checked_at and freshness_status. Do not transform list prices into transaction claims. For editorial text, quote briefly and link to the canonical story. Prefer https://siliconticker.com/indices/cl-fcr for a human-readable CL-FCR citation and https://siliconticker.com/api/markets for machine use. ## Source rights The broad public-cloud market observations use the CC-BY-4.0 GPU Cloud Compare dataset with attribution. The separate Azure Spot tape uses Microsoft's official public Retail Prices API as a vendor tariff; SiliconTicker does not assert a broad redistribution license for it. ORNN is listed because it publishes an hourly transaction-based compute index, but its values are not embedded: its terms require a commercial redistribution agreement. The source registry at https://siliconticker.com/api/sources is authoritative for connection and rights status. ## Failure and cache behavior Market and news connectors refresh on the first request after the one-hour shared cache expires. When an upstream market refresh fails, the service may return the last successful snapshot and label it stale rather than inventing values. The Azure feed never substitutes a fabricated static price. Inspect https://siliconticker.com/api/health and response freshness fields before relying on a snapshot. ## Human pages - GPU Rental Pricing: Hourly Rates and Total Cost: https://siliconticker.com/learn/gpu-rental-pricing - H100 vs A100: Compare GPUs by Workload Cost: https://siliconticker.com/learn/h100-vs-a100 - Spot vs On-Demand GPUs: Price, Capacity and Risk: https://siliconticker.com/learn/spot-vs-on-demand-gpus - AI Agent Guide to GPU Prices and Compute Market Data: https://siliconticker.com/agents - Market board: https://siliconticker.com/markets - US hardware acceleration market guide: https://siliconticker.com/markets/us-hardware-acceleration - CL-FCR record: https://siliconticker.com/indices/cl-fcr - News: https://siliconticker.com/news - AI accelerator chip news this week: https://siliconticker.com/news/ai-accelerator-chip-news - Investing education: https://siliconticker.com/learn - Methodology: https://siliconticker.com/methodology - Editorial standards and corrections: https://siliconticker.com/about - RSS: https://siliconticker.com/feed.xml ## Localized human overviews - Español: https://siliconticker.com/es - Deutsch: https://siliconticker.com/de - Français: https://siliconticker.com/fr - 日本語: https://siliconticker.com/ja These pages provide translated market context and link to the English detailed pages and language-neutral JSON contracts.
