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 If any complete set is present, skip the full setup and proceed with API calls; when making requests, use the resolution order in "Making Requests" below (pick the pair that matches the user's account context when multiple sets exist). Do not ask the user to run derivation one-liners or merge keys into a header. Only guide users through the full setup process below when no complete credential set exists. Important: Before making any API calls, always ask the user which environment they want to use: LIVE (real money) or DEMO (paper trading). Do not assume the environment. API Keys Are Environment-Specific API keys are tied to a specific environment and cannot be used across environments.

Optional: To precompute the header from key/secret, you can set: export T212_AUTH_HEADER= "Basic $(echo -n " $T212_API_KEY : $T212_API_SECRET " | base64) " Otherwise, the agent builds the header from T212_API_KEY and T212_API_SECRET when making requests. Manual (placeholders): # Format: T212_AUTH_HEADER = "Basic " + base64(API_KEY_ID:API_SECRET) export T212_AUTH_HEADER= "Basic $(echo -n "<YOUR_API_KEY_ID>:<YOUR_API_SECRET>" | base64) " # Example with sample credentials: export T212_AUTH_HEADER= "Basic $(echo -n "35839398ZFVKUxpHzPiVsxKdOtZdaDJSrvyPF:7MOzYJlVJgxoPjdZJCEH3fO9ee7A0NzLylFFD4-3tlo" | base64) " Making Requests When making API calls, use the first option that applies (semantically: pick the credential set that matches the user's account, or the only set present): If T212_AUTH_HEADER and T212_BASE_URL are set: use them in requests. Else if T212_API_KEY and T212_API_SECRET are set: use this pair (single account). Build header as Basic $(echo -n "$T212_API_KEY:$T212_API_SECRET" | base64) and base URL as https://${T212_ENV:-live}.trading212.com . Do not guide the user to derive or merge; you do it. Else if both account-specific pairs are set ( T212_API_KEY_INVEST / T212_API_SECRET_INVEST and T212_API_KEY_STOCKS_ISA / T212_API_SECRET_STOCKS_ISA ): the user must clearly specify which account to target (Invest or Stocks ISA), unless they ask for information for all accounts . Use the Invest pair when the user refers to Invest, and the Stocks ISA pair when the user refers to ISA/Stocks ISA. If the user wants information for all accounts, make multiple API calls—one per account (Invest and Stocks ISA)—and present or aggregate the results for both. If it is not clear from context which account to use (and they did not ask for all accounts), ask for confirmation before making API calls (e.g. "Which account should I use — Invest or Stocks ISA?"). Do not assume. Build the header from the chosen key/secret and base URL as https://${T212_ENV:-live}.trading212.com . Else if only the Invest pair is set ( T212_API_KEY_INVEST and T212_API_SECRET_INVEST ): use this pair for requests; if the user asks about Stocks ISA, only the Invest account is configured. Else if only the Stocks ISA pair is set ( T212_API_KEY_STOCKS_ISA and T212_API_SECRET_STOCKS_ISA ): use this pair for requests; if the user asks about Invest, only the Stocks ISA account is configured. Use the T212_AUTH_HEADER value in the Authorization header when it is set: # When T212_AUTH_HEADER and T212_BASE_URL are set: curl -H "Authorization: $T212_AUTH_HEADER " \ " ${T212_BASE_URL} /api/v0/equity/account/summary" When only primary vars are set, use the inline form in the curl: # When only T212_API_KEY, T212_API_SECRET, T212_ENV are set: curl -H "Authorization: Basic $(echo -n " $T212_API_KEY : $T212_API_SECRET " | base64) " \ "https:// ${T212_ENV:-live} .trading212.com/api/v0/equity/account/summary" Warning: T212_AUTH_HEADER must be the full header value including the Basic prefix. # WRONG - raw base64 without "Basic " prefix curl -H "Authorization: <base64-only>" ... # This will NOT work! # CORRECT - use T212_AUTH_HEADER (contains "Basic <base64>") curl -H "Authorization: $T212_AUTH_HEADER " ... # This works Environment Variables Single account vs all accounts: API keys are for a single account . One key/secret pair ( T212_API_KEY + T212_API_SECRET ) = one account (Invest or Stocks ISA). To use all accounts (Invest and Stocks ISA), the user must set two sets of key/secret: T212_API_KEY_INVEST / T212_API_SECRET_INVEST and T212_API_KEY_STOCKS_ISA / T212_API_SECRET_STOCKS_ISA . When both pairs are set, the user must clearly specify which account to target; if it is not clear from context, ask for confirmation (Invest or Stocks ISA) before making API calls. Primary (single account): Set these for consistent setup with the plugin README: export T212_API_KEY= "your-api-key" # API Key (ID) from Trading 212 export T212_API_SECRET= "your-api-secret" export T212_ENV= "demo" # or "live" (defaults to "live" if unset) Account-specific (Invest and/or Stocks ISA): Set only the pair(s) you use. One complete set (key + secret for the same account) is enough. For example, only Invest: export T212_API_KEY_INVEST= "your-invest-api-key" export T212_API_SECRET_INVEST= "your-invest-api-secret" export T212_ENV= "demo" # or "live" For both accounts, set both pairs: export T212_API_KEY_INVEST= "your-invest-api-key" export T212_API_SECRET_INVEST= "your-invest-api-secret" export T212_API_KEY_STOCKS_ISA= "your-stocks-isa-api-key" export T212_API_SECRET_STOCKS_ISA= "your-stocks-isa-api-secret" export T212_ENV= "demo" # or "live" (applies to both) Optional – precomputed (for scripts or if the user prefers): The user can set the auth header and base URL from the primary vars, but they do not need to; when making API calls you (the agent) must build the header and base URL from primary vars if these are not set. # Build auth header and base URL from T212_API_KEY, T212_API_SECRET, T212_ENV export T212_AUTH_HEADER= "Basic $(echo -n " $T212_API_KEY : $T212_API_SECRET " | base64) " export T212_BASE_URL= "https:// ${T212_ENV:-live} .trading212.com" Alternative (manual): If you prefer not to store key/secret in env, set derived vars directly. Remember: API keys only work with their matching environment. # For DEMO (paper trading) export T212_AUTH_HEADER= "Basic $(echo -n "<DEMO_API_KEY_ID>:<DEMO_API_SECRET>" | base64) " export T212_BASE_URL= "https://demo.trading212.com" # For LIVE (real money) - generate separate credentials in LIVE account # export T212_AUTH_HEADER="Basic $(echo -n "<LIVE_API_KEY_ID>:<LIVE_API_SECRET>" | base64)" # export T212_BASE_URL="https://live.trading212.com" Tip: If you use both environments, use separate variable names: # Demo credentials export T212_DEMO_AUTH_HEADER= "Basic $(echo -n "<DEMO_KEY_ID>:<DEMO_SECRET>" | base64) " # Live credentials export T212_LIVE_AUTH_HEADER= "Basic $(echo -n "<LIVE_KEY_ID>:<LIVE_SECRET>" | base64) " Common Auth Errors Code Cause Solution 401 Invalid credentials Check API key/secret, ensure no extra whitespace 401 Environment mismatch LIVE API keys don't work with DEMO and vice versa - verify key matches target environment 403 Missing permissions Check API permissions in Trading 212 settings 408 Request timed out Retry the request 429 Rate limit exceeded Wait for x-ratelimit-reset timestamp Account Get Account Summary GET /api/v0/equity/account/summary (1 req/5s) curl -H "Authorization: $T212_AUTH_HEADER " \ " $T212_BASE_URL /api/v0/equity/account/summary" Response Schema: { "id" : 12345678 , "currency" : "GBP" , "totalValue" : 15250.75 , "cash" : { "availableToTrade" : 2500.5 , "reservedForOrders" : 150.0 , "inPies" : 500.0 } , "investments" : { "currentValue" : 12100.25 , "totalCost" : 10500.0 ,
