Use it to find markets, place a single market order, write NautilusTrader strategies, test them with historical filled trades, fund an account, or monitor a live deployment.
Why use it?
It brings market discovery, trading, historical testing, funding, and deployment into one workflow instead of requiring separate tools.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

polymarket scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Polymarket Prediction Market Trading

Trade prediction markets on Polymarket through Superior Trade. Discover markets, place single immediate market orders, write NautilusTrader strategies, backtest against historical trade data, and deploy live — all through one API.

Read ../../references/unified-runtime.md before any Superior Trade request. Use only methods, fields, and capabilities published by Unified OpenAPI.

Base URL: https://api.superior.trade. If the environment configures a different base URL, use that instead. Auth: Prefer x-api-key: <api_key> for Superior Trade product API keys. Browser/session callers may use Authorization: Bearer <token>. Docs: GET /openapi.json (Unified OpenAPI contract)

Reference files

Load these on demand — each is the full detail behind a summary below.

Read When
references/api.md You need Unified route selection for account, wallet, market discovery, typed execution, backtest, or deployment.
references/strategy-authoring.md You are writing NautilusTrader strategy code — structure, order submission, dollars-to-shares conversion, multi-instrument setups, available data.
references/example-strategies.md You want a worked starting point: carry/yield harvesting, momentum/news fade, or spread capture.
references/strategies.md You are choosing an archetype for the user's thesis and need the fit/anti-fit table.
references/troubleshooting.md A strategy source, backtest, or deployment is failing, or a deployment trades zero times.

Gotchas

Environment-specific facts that defy reasonable assumptions. Read these before acting.

  • Wallet reads are not bootstrap or funding mutations. Use GET /wallet only for the managed wallet data it returns. If a required Polymarket funding action is absent from the Unified contract, report it as unavailable.
  • Backtests are built from filled TradeTick data, not a full order book. They cannot model queue position or liquidity, so a strategy that depends on resting-order fills will look better in backtest than it trades. Say this when presenting results.
  • An exact market slug is required before writing a strategy. Get it from GET /context/markets; if the user pastes a Polymarket event URL, pass the whole URL as the query so child markets expand.
  • Prices are probabilities between 0 and 1. Sizing is in shares, not dollars — convert with shares = dollars / price (see references/strategy-authoring.md).
  • Credential storage is contract-defined. Use only the form published for PUT /runtime/deployments/{id}/credentials; never infer or send undisclosed key material.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
