What is G-Prophet?
G-Prophet is an auditable quantitative market research platform that turns market data and model outputs into reviewable research records. It helps users compare model projections, uncertainty, and subsequent market outcomes rather than providing personalized trading instructions.
The platform is operated by GPROPHET LIMITED, a UK private limited company (Company No. 16777200, incorporated 10 October 2025). It provides observed market data, quantitative model projections and uncertainty ranges, technical indicators, multi-model comparisons, and research records. G-Prophet is designed for research, model observation, and retrospective evaluation. Its outputs are not personalized investment advice, trading recommendations, or instructions to buy, sell, or hold financial instruments. Users can compare model reference paths with subsequent market outcomes after each evaluation horizon matures; historical results do not guarantee future performance.

How does G-Prophet work?
- Read observed market data and the selected instrument, market, and evaluation horizon.
- Run one or more quantitative models and return model reference paths, direction observations, and uncertainty ranges.
- Store the research record with its model, inputs, and target period.
- After the target period, compare the record with verified market outcomes and review performance metrics.
Does G-Prophet provide investment advice?
No. G-Prophet does not provide personalized investment advice, trading recommendations, or instructions to buy, sell, or hold a financial instrument. Model output is research material and does not make a decision for the user.
Does G-Prophet guarantee prediction accuracy?
No. Market outcomes are uncertain and no accuracy level is guaranteed. Historical evaluation uses matured records with verified outcomes. Direction consistency compares the direction of the model reference price with the later observed direction from the recorded current price. Price proximity is calculated as 100% minus mean SMAPE; it is not a return. Pending records without verified outcomes are excluded from these metrics. Model stability is a model-reported score, not a calibrated probability of being correct.
Does G-Prophet provide an API?
Yes. The external API exposes market data, quantitative model projections, technical indicators, market context, and asynchronous research reports. Public health and API information endpoints do not require a key; paid and account operations require an API key.
Can AI agents use G-Prophet?
Yes. Developers can use the official Python SDK and MCP server with compatible agent clients. Agents should present returned paths and metrics as research observations, retain uncertainty and provenance, and avoid converting outputs into personalized trading instructions.
How is G-Prophet different from an LLM?
G-Prophet provides structured market data, quantitative model outputs, uncertainty fields, and reviewable research records through documented APIs. An LLM can help explain or compare those records in natural language, but generated text is not itself a verified market observation or a guarantee of an outcome.
Where can company information be verified?
The legal name, company number, registered office, and incorporation date can be checked in the UK Companies House public register.
