# MagicON AI > RF module and PCB stackup design engines, callable over plain HTTPS with no > account and no API key. Deterministic solvers - cascade analysis, receiver > planning, T/R safety budgets, impedance/stackup solving, thermal, PDN and > regulatory compliance - over a catalog of 2,400+ real RF components. The > engines compute; they do not guess. A slot no catalog part can fill comes back > declared empty rather than filled with an assumption. If you are an AI agent and want to call the design engines, read the API page first - it is written for you, not for a human reader. ## For agents - [API reference for LLMs](https://pcbgenerator.com/docs/llm/): every public engine, its exact path, its rate limit, a worked example with real numbers, and what we do and do not stand behind. - [Design a 9.4 GHz T/R module from Claude Code](https://pcbgenerator.com/docs/walkthroughs/design-a-tr-module-from-claude-code/): an end-to-end worked tutorial - one HTTP call returns a complete X-band radar front end with real parts, a $939.99 BOM, and thirteen disclosures including a compressed LNA it caught. - [OpenAPI schema](https://api.pcbgenerator.com/openapi.json): machine-readable request/response schemas for every route. - [Interactive API docs](https://api.pcbgenerator.com/docs): the same schema, browsable. - [How we ground our numbers](https://pcbgenerator.com/how-we-ground): what "computed" means here, and how a figure an agent asserted is distinguished from one an engine produced. ## Free tools (no account) - [Receiver designer](https://pcbgenerator.com/tools/receiver): superheterodyne receiver - frequency plan, cascade NF, sensitivity, ADC interface, part selection. - [Link budget calculator](https://pcbgenerator.com/tools/link-budget): cascaded gain, Friis noise figure, OIP3, P1dB headroom. - [Impedance calculator](https://pcbgenerator.com/tools/impedance): microstrip, stripline and differential impedance. - [PCB stackup designer](https://pcbgenerator.com/tools/stackup): up to 32 layers, FR4 through Rogers and MEGTRON6. - [Radar performance](https://pcbgenerator.com/tools/radar): range equation and waveform budget. - [OTA link budget](https://pcbgenerator.com/tools/ota-link): one-way Friis / free-space path loss. - [Planar filter calculator](https://pcbgenerator.com/tools/planar-filter-calculator): distributed filter synthesis. - [Patch antenna calculator](https://pcbgenerator.com/tools/antenna-calculator): planar antenna geometry. ## Product - [Home](https://pcbgenerator.com/): what MagicON AI is. - [Pricing](https://pcbgenerator.com/pricing). ## Documentation - [Documentation home](https://pcbgenerator.com/docs/): the manual. - [Quick start](https://pcbgenerator.com/docs/getting-started/quick-start/): first design, end to end. - [Features](https://pcbgenerator.com/docs/FEATURES/): what the platform does. - [Architecture](https://pcbgenerator.com/docs/ARCHITECTURE/): how the frontend, API and solvers fit together. - [Complete guide](https://pcbgenerator.com/docs/complete-guide/): the long-form manual. - [RF chain design rules](https://pcbgenerator.com/docs/reports/RF_CHAIN_DESIGN_RULES/): the constraints the selection engine enforces. - [Troubleshooting](https://pcbgenerator.com/docs/TROUBLESHOOTING/). ## Notes - There is no MCP server yet. HTTPS is the only transport today. - All design engines are stateless: one request in, one complete result out. Nothing is stored, and there is no job queue to poll. - Rate limits are per IP address and are listed per endpoint on the API page.
