Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00145 | $0.11008 |
| Opus 5 | $0.00072 | $0.05504 |
| Sonnet 5 | $0.00029 | $0.02202 |
| Haiku 4.5 | $0.00015 | $0.01101 |
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.

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

trading212-api is a skill published in the GitHub repository trading212-labs/agent-skills (115 stars, last pushed 4d ago), licensed MIT. It adds 145 tokens to every session and 11,008 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
