AI apps and API
AI apps and API
The tools an AI app can call, from the list the server itself serves, and the limits on them. There is no general web API today.
On this page
The MCP server
The server is at https://quantistrade.co.uk/mcp (MCP over Streamable HTTP). Connections and AI apps explains how to connect, by signing in or with a key.
Tools
| Tool | Cost | What it does | Limits |
|---|---|---|---|
search_evidence (any key or connected app) | Free | Searches the public evidence corpus of house backtests (fixed universes in the US, UK and EU; 5 to 20-year windows; the same costs). Returns matching runs with their metrics and links, counting refused and never-fired runs. | Stored runs only: it doesn't run anything and holds no user results. |
list_templates (any key or connected app) | Free | The community strategy templates: each rule, its symbols, the exact prompt the Strategy Agent receives, and its house backtest when one is stored. | Doesn't run a template; pass its prompt to estimate_backtest_cost or run_backtest. |
explain_metric (any key or connected app) | Free | The Education Centre's definition of a result-card metric (what it is, why it matters, the formula) with a link to the full article when one is published. | Definitions only; it doesn't compute a metric for a strategy. |
methodology (any key or connected app) | Free | How a result card is calculated: costs, dividends and taxes; big falls when its history is reshuffled; could it be luck; where the gains came from; the evidence corpus; token pricing; concept articles. | Explains; doesn't compute. |
estimate_backtest_cost (any key or connected app) | Free (nothing runs) | Reads a plain-English strategy exactly as the Strategy Agent would and returns what would run (symbols, period, the rules as the result card will state them), the price in tokens and your balance, or the clarification or refusal the agent would give. | Never charges. |
run_backtest (needs the Run backtests scope) | Spends your tokens: 300 for every backtest, the same price as the website | Runs a strategy through the Strategy Agent: the same parser, prices, trial ledger and refunds as the website. Returns the verdict, key metrics, the exact rules, the cost basis and links to the full result card and its reproduce bundle, or a result id if it takes longer than the wait. | Needs max_tokens: a run above it, or above your balance, is refused before anything is charged. Daily data, at most 20 years. Goal prompts go to goal_search. |
get_backtest (any key or connected app) | Free | Fetches one of your own results by id: status, verdict, metrics, rules, cost basis, tokens charged and refunded, links. | Your account's results only. |
goal_search (needs the Run backtests scope) | Spends your tokens: 2,100 tokens for the default 24 candidates (as much as 7 tests, more than the free trial's 1,000 tokens) | Searches a fixed, documented list of candidate strategies for one meeting your goal, chosen on in-sample years and judged on held-out years, every candidate counted. | Needs max_tokens covering the quoted price. Usually takes minutes: it returns a result id for get_backtest. |
Limits
- 60 MCP requests a minute per key (and per connected app).
- 60 cost estimates, runs and goal searches an hour per account, of which at most 20 runs and goal searches.
- Up to 10 active keys per account. Strategy descriptions up to 1,000 characters.
- Backtests use daily data and at most 20 years, as on the website.
A general web API
There is no general web API for Quantis Trade today. The MCP server is the way in for programs, with the same prices, limits and records as the website.
