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

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.

If you get a 401 error, verify that:

1. You're using the correct API key for the target environment
2. The API key was generated in the same environment (LIVE or DEMO) you're trying to access

Get Credentials

1. Decide which environment to use - LIVE (real money) or DEMO (paper trading)
2. Open Trading 212 app (mobile or web)
3. Switch to the correct account - Make sure you're in LIVE or DEMO mode matching your target environment
4. Navigate to Settings > API
5. Generate a new API key pair - you'll receive:
   • API Key (ID) (e.g., 35839398ZFVKUxpHzPiVsxKdOtZdaDJSrvyPF)
   • API Secret (e.g., 7MOzYJlVJgxoPjdZJCEH3fO9ee7A0NzLylFFD4-3tlo)
6. Store the credentials separately for each environment if you use both

Building the Auth Header

Combine your API Key (ID) and Secret with a colon, base64 encode, and prefix with Basic for the Authorization header.

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):

• IfT212_AUTH_HEADER and T212_BASE_URL are set: use them in requests.
• Else ifT212_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/): the user must clearly specify which account to target (Invest or Stocks ISA), unless they ask for information for . Use the Invest pair when the user refers to Invest, and the Stocks ISA pair when the user refers to ISA/Stocks ISA. (Invest and Stocks ISA)—and present or aggregate the results for both. (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 .

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)"

Instruments

Ticker Lookup Workflow

When users reference instruments by common names (e.g., "SAP", "Apple", "AAPL"), you must look up the exact Trading 212 ticker before making any order, position, or historical data queries. Never construct ticker formats manually.

CACHE FIRST: Always check /tmp/t212_instruments.json before calling the API. The instruments endpoint has a 50-second rate limit and returns ~5MB. Only call the API if cache is missing or older than 1 hour.

Generic search: Match the user's search term in the three meaningful fields: ticker, name, or shortName. Use one variable (e.g. SEARCH_TERM) with test($q; "i") on each field so "TSLA", "Tesla", "TL0", etc. match efficiently. For regional filtering (e.g. "US stocks", "European SAP"), use the ISIN prefix (first 2 characters) for country code or currencyCode after the grep.

IMPORTANT: Never auto-select instruments. If multiple options exist, you are required to ask the user for their preference.

# SEARCH_TERM = user query (e.g. TSLA, Tesla, AAPL, SAP)
SEARCH_TERM="TSLA"
CACHE_FILE="/tmp/t212_instruments.json"
if [ -f "$CACHE_FILE" ] && [ $(($(date +%s) - $(stat -f %m "$CACHE_FILE" 2>/dev/null || stat -c %Y "$CACHE_FILE"))) -lt 3600 ]; then
  # Search ticker, name, or shortName fields
  jq --arg q "$SEARCH_TERM" '[.[] | select((.ticker // "" | test($q; "i")) or (.name // "" | test($q; "i")) or (.shortName // "" | test($q; "i")))]' "$CACHE_FILE"
else
  curl -s -H "Authorization: $T212_AUTH_HEADER" \

  RESPONSE=$(curl -s -H "Authorization: $T212_AUTH_HEADER" \
    "$T212_BASE_URL$NEXT_PATH")

  # Process items (e.g., save to file)
  echo "$RESPONSE" | jq '.items[]' >> orders.json

  # Get next page path (null if no more pages)
  NEXT_PATH=$(echo "$RESPONSE" | jq -r '.nextPagePath // empty')

  # Wait 1 second between requests (50 req/min limit)

Pre-Order Validation

Before BUY - Check Available Funds

#!/bin/bash
# Validate funds before placing a buy order

TICKER="AAPL_US_EQ"
QUANTITY=10
ESTIMATED_PRICE=185.00
ESTIMATED_COST=$(echo "$QUANTITY * $ESTIMATED_PRICE" | bc)

# Get available funds
AVAILABLE=$(curl -s -H "Authorization: $T212_AUTH_HEADER" \
  "$T212_BASE_URL/api/v0/equity/account/summary" | jq '.cash.availableToTrade')

echo "Estimated cost: $ESTIMATED_COST"
echo "Available funds: $AVAILABLE"

if (( $(echo "$ESTIMATED_COST > $AVAILABLE" | bc -l) )); then
  echo "ERROR: Insufficient funds"
  exit 1
fi

echo "OK: Funds available, proceeding with order"

Before SELL - Check Available Shares

#!/bin/bash
# Validate position before placing a sell order

TICKER="AAPL_US_EQ"
SELL_QUANTITY=5

# Get position for the ticker
POSITION=$(curl -s -H "Authorization: $T212_AUTH_HEADER" \
  "$T212_BASE_URL/api/v0/equity/positions?ticker=$TICKER")

AVAILABLE_QTY=$(echo "$POSITION" | jq '.[0].quantityAvailableForTrading // 0')

echo "Sell quantity: $SELL_QUANTITY"
echo "Available to sell: $AVAILABLE_QTY"

if (( $(echo "$SELL_QUANTITY > $AVAILABLE_QTY" | bc -l) )); then
  echo "ERROR: Insufficient shares (some may be in pies)"
  exit 1
fi

echo "OK: Shares available, proceeding with order"

Rate Limit Handling

Understanding Rate Limits

Rate limits are per-account , not per API key or IP address. If you have multiple applications using the same Trading 212 account, they share the same rate limit pool.

Response Headers

Every API response includes rate limit headers:

Avoid Burst Requests to avoid Rate Limiting

Do not send requests in bursts. Even if an endpoint allows 50 requests per minute, sending them all at once can trigger rate limiting and degrade performance. Pace your requests evenly, for example, by making one call every 1.2 seconds, ensuring you always stay within the limit.

Bad approach (bursting):

# DON'T DO THIS - sends all requests at once
for ticker in AAPL_US_EQ MSFT_US_EQ GOOGL_US_EQ; do
  curl -H "Authorization: $T212_AUTH_HEADER" \
    "$T212_BASE_URL/api/v0/equity/positions?ticker=$ticker" &
done
wait

Good approach (paced):

# DO THIS - space requests evenly
for ticker in AAPL_US_EQ MSFT_US_EQ GOOGL_US_EQ; do
  curl -H "Authorization: $T212_AUTH_HEADER" \
    "$T212_BASE_URL/api/v0/equity/positions?ticker=$ticker"
  sleep 1.2  # 1.2 second between requests for 50 req/m limit
done

Caching Strategy

For data that doesn't change frequently, cache locally to reduce API calls:

#!/bin/bash
# Cache instruments list (changes rarely)

CACHE_FILE="/tmp/t212_instruments.json"
CACHE_MAX_AGE=3600  # 1 hour

if [ -f "$CACHE_FILE" ]; then
  CACHE_AGE=$(($(date +%s) - $(stat -f %m "$CACHE_FILE")))
  if [ "$CACHE_AGE" -lt "$CACHE_MAX_AGE" ]; then
    cat "$CACHE_FILE"
    exit 0
  fi
fi

# Cache expired or doesn't exist - fetch fresh data
curl -s -H "Authorization: $T212_AUTH_HEADER" \
  "$T212_BASE_URL/api/v0/equity/metadata/instruments" > "$CACHE_FILE"

cat "$CACHE_FILE"

Safety Guidelines

1. Test in demo first - Always validate workflows before live trading
2. Validate before ordering - Check funds (cash.availableToTrade) before buy, positions (quantityAvailableForTrading) before sell
3. Confirm destructive actions - Order placement and cancellation are irreversible
4. API is not idempotent - Duplicate requests may create duplicate orders
5. Never log credentials - Use environment variables
6. Respect rate limits - Space requests evenly, never burst
7. Max 50 pending orders - Per ticker, per account
8. Cache metadata - Instruments and exchanges change rarely
