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

trading212-api scanned grade A with 1 finding 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 3d ago.

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.

Trading 212 API

Note: The Trading 212 API is currently in beta and under active development. Some endpoints or behaviors may change.

Quick Reference

Environments

Environment Base URL Purpose
Demo https://demo.trading212.com/api/v0 Paper trading - test without real funds
Live https://live.trading212.com/api/v0 Real money trading

Order Quantity Convention

  • Positive quantity = BUY (e.g., 10 buys 10 shares)
  • Negative quantity = SELL (e.g., -10 sells 10 shares)

Account Types

Only Invest and Stocks ISA accounts are supported.

Instrument Identifiers

Trading 212 uses custom tickers as unique identifiers for instruments. Always search for the Trading 212 ticker before making instrument requests.


Authentication

HTTP Basic Auth with API Key (username) and API Secret (password).

Check Existing Setup First

Before guiding the user through authentication setup, check if credentials are already configured:

Semantic rule: Credentials are configured when at least one complete set is present: a complete set is key + secret for the same account (e.g. T212_API_KEY + T212_API_SECRET, or T212_API_KEY_INVEST + T212_API_SECRET_INVEST, or T212_API_KEY_STOCKS_ISA + T212_API_SECRET_STOCKS_ISA). You do not need all four account-specific vars; having only the Invest pair or only the Stocks ISA pair is enough. Check for any combination that gives at least one usable key+secret pair.

# Example: configured if any complete credential set exists
if [ -n "$T212_AUTH_HEADER" ] && [ -n "$T212_BASE_URL" ]; then
  echo "Configured (derived vars)"
elif [ -n "$T212_API_KEY" ] && [ -n "$T212_API_SECRET" ]; then
  echo "Configured (single account)"
elif [ -n "$T212_API_KEY_INVEST" ] && [ -n "$T212_API_SECRET_INVEST" ]; then
  echo "Configured (Invest); Stocks ISA also if T212_API_KEY_STOCKS_ISA and T212_API_SECRET_STOCKS_ISA are set"
elif [ -n "$T212_API_KEY_STOCKS_ISA" ] && [ -n "$T212_API_SECRET_STOCKS_ISA" ]; then
  echo "Configured (Stocks ISA); Invest also if T212_API_KEY_INVEST and T212_API_SECRET_INVEST are set"
else
  echo "No complete credential set found"
fi

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.
