API to Get the TTF Gas Price

You need a reliable way to fetch the latest TTF Gas price for finance workflows like P&L, VaR, and hedging dashboards. By the end of this guide you will be able to query the Energy API for the TTF Gas quote, parse the result safely for EUR/MWh workflows, and ship a production-ready first request using curl and Python.

What the TTF Gas price represents (finance context)

TTF Gas is a liquid European natural gas benchmark used across risk, pricing, and settlement workflows. In finance, it’s commonly referenced for commodity exposure measurement, contract indexation, and mark-to-market. In the Energy API, the symbol name is “TTF Gas” and the exact symbol code is TTF_GAS, with a unit of EUR/MWh.

Illustration: API to Get the TTF Gas Price

Because portfolios and ledgers often mix energy and FX, you will want to read two dimensions carefully from the API response: the unit (EUR/MWh) and the currency reported for the symbol in the response payload. This lets you normalize to your reporting currency with clearly documented provenance.

Endpoint, authentication, and the single symbol you need

You’ll use a single GET endpoint to retrieve the latest price:

Endpoint: GET https://energy-api.com/api/v1/latest
Query parameter: symbols=TTF_GAS
Authentication: api_key query parameter with your API key

Important integration notes for finance:

Do not add base=USD or any forced base conversion when you need TTF_GAS (or EUA_CO2). The Energy API can return a different base per symbol, and the “base” field may be MIXED at times; always inspect currencies.TTF_GAS when calculating exposure.
Units are EUR/MWh. Keep this unit chained through your valuation stack. If you convert quantities (e.g., MWh to therms) or currencies (EUR to USD), record the conversion rates and timestamps to preserve auditability.
Starter plan is $19.99/month with a 7‑day / 50‑call trial. Use that window to implement tests and monitoring before moving to production.

Your first TTF Gas request (curl)

Make a minimal, copy-pasteable latest-quote call for the TTF_GAS symbol. This is suitable for CI checks or ad-hoc terminal pulls.

curl -G "https://energy-api.com/api/v1/latest" --data-urlencode "symbols=TTF_GAS" --data-urlencode "api_key=YOUR_API_KEY"

Notes for finance teams:

Keep YOUR_API_KEY in a secret manager; avoid committing it to version control.
Because you’re fetching a single symbol, responses are small and fast. Add lightweight retries with jitter when wiring into jobs.
Persist both the date and currencies fields, not just the numeric rate. This helps reconcile backtests and monthly closes.

Official sample payloads you should model against

The API publishes a uniform schema across symbols. Below are two official, copy-exact samples you can use to wire JSON parsing, field names, and data types.

Schema-fit example (official sample, different symbol)

This confirms endpoint shape and fields you’ll parse in your client. Copy the field names exactly in your code.

{
"success": true,
"date": "2026-11-15",
"base": "EUR",
"rates": {
"OMIE_ES_DA": 91.3699
},
"dates": {
"OMIE_ES_DA": "2026-11-15"
},
"currencies": {
"OMIE_ES_DA": "EUR"
},
"base_filter_note": null,
"missing_symbols": null
}

Real TTF Gas example (copy these exact values)

This is an actual TTF_GAS response snapshot you can use in tests. The unit of measure is EUR/MWh; the currencies.TTF_GAS field tells you the currency the rate is quoted in.

{"success":true,"date":"2026-09-01","base":"USD","rates":{"TTF_GAS":25.494},"dates":{"TTF_GAS":"2026-09-01"},"currencies":{"TTF_GAS":"USD"},"base_filter_note":null,"missing_symbols":null}

Field usage in finance workflows:

rates.TTF_GAS: numeric price for TTF Gas.
dates.TTF_GAS: the data date for that price; store this with the quote.
currencies.TTF_GAS: currency of the price value; do not rely solely on the top-level base for per-symbol currency—always read this field to be safe.
date: often the service day for the batch; keep it for operations logs but prefer dates.TTF_GAS for symbol-level dating.

Another TTF Gas response example (same structure)

Use this identical structure in unit tests to verify idempotent parsing and correct field access for TTF_GAS without assumptions about base conversion.

{"success":true,"date":"2026-09-01","base":"USD","rates":{"TTF_GAS":25.494},"dates":{"TTF_GAS":"2026-09-01"},"currencies":{"TTF_GAS":"USD"},"base_filter_note":null,"missing_symbols":null}

Read the fields you actually need (Python)

Below is a compact Python example that calls the latest endpoint for TTF_GAS, validates success, then extracts the price, price currency, and symbol date you will store in your pricing table. It deliberately avoids passing a base parameter so you don’t trigger unwanted conversions.

# Python 3.x
import os
import sys
import json
import urllib.parse
import urllib.request

API_URL = "https://energy-api.com/api/v1/latest"
params = {
"symbols": "TTF_GAS",
"api_key": "YOUR_API_KEY"
}
url = API_URL + "?" + urllib.parse.urlencode(params)

try:
with urllib.request.urlopen(url, timeout=15) as resp:
body = resp.read().decode("utf-8")
data = json.loads(body)
except Exception as e:
print("Request failed:", e, file=sys.stderr)
sys.exit(1)

# Basic validation
if not data.get("success"):
print("API reported failure:", body, file=sys.stderr)
sys.exit(2)

rates = data.get("rates", {})
dates = data.get("dates", {})
currs = data.get("currencies", {})

# Extract TTF Gas fields
symbol = "TTF_GAS"
if symbol not in rates:
print("Missing TTF_GAS rate in response:", body, file=sys.stderr)
sys.exit(3)

ttf_price = rates[symbol]
ttf_date = dates.get(symbol)
ttf_ccy = currs.get(symbol)

# Print normalized record you can upsert into a pricing table
record = {
"symbol": symbol,
"price": ttf_price,
"price_currency": ttf_ccy,
"symbol_date": ttf_date,
"uom": "EUR/MWh" # From catalog facts; not returned in payload
}
print(json.dumps(record))

Storage guidance for finance:

Persist a tuple of (symbol, symbol_date, price, price_currency, uom). This allows controlled currency and unit conversions later without re-fetching.
Do not assume the top-level base applies to each symbol; always use currencies.TTF_GAS.
If you need cross-currency consolidation, run an FX conversion step downstream using your preferred FX source, timestamped at the same valuation cutoff.

How the schema maps to your P&L and risk pipeline

When marking positions, tie the quantity dimension (MWh) to the unit (EUR/MWh) and multiply by the retrieved price. If you hold quantities in other energy units, convert to MWh first, then multiply by the TTF_GAS price for clean dimensional analysis. Keep conversions and rates auditable by logging their sources and effective dates.

Exposure: Notional_EUR = Quantity_MWh × Price_EUR_per_MWh (if currencies.TTF_GAS is EUR). If currencies.TTF_GAS is USD, treat the price as USD/MWh and convert to EUR or your home currency as needed.
Backtesting: Align dates.TTF_GAS with your trade-date or end-of-day convention to avoid time skews in returns.
Hedging: Quote extraction should be idempotent and cached for a fixed cutoff to match hedge accounting snapshots.

Production considerations for finance teams

Integrate the following operational controls from day one so you avoid reconciliation gaps during quarter-end or audit:

Caching and cutoffs: Cache the latest quote once per valuation cutoff to ensure deterministic reports. Keep a keyed cache by (symbol, symbol_date).
Non-trading days: Energy benchmarks can publish on calendar schedules that may differ from equity calendars. Handle repeated dates.TTF_GAS gracefully and avoid overwriting unless the published value changes.
Retries and timeouts: Use short timeouts (10–20s) and limited retries with backoff. Log non-200 responses alongside the full response body when available.
Idempotency: Your upsert key should be (symbol, symbol_date). No pagination is required for a single-symbol latest call.
Audits: Persist the full raw JSON alongside parsed fields for replay. This makes audit queries and internal model validations faster.

Field-by-field quick reference

These are the specific fields you will typically persist in a finance data store:

rates.TTF_GAS: numeric price, read as a decimal string or float with your chosen precision.
dates.TTF_GAS: symbol-level date; use this as the valuation date for that price.
currencies.TTF_GAS: currency of the price; do not rely solely on top-level base.
date: top-level service date; store for lineage but do not substitute for dates.TTF_GAS in valuations.
base: may differ from per-symbol currencies; documentation notes base may be MIXED in broader calls.

End-to-end sample: request to parsed quote

Use the following blocks to validate your ingestion and parsing without guessing formats. The curl request corresponds to the response examples you used for testing.

Common pitfalls and how to avoid them

Forcing a base currency: Avoid passing any base parameter when fetching TTF_GAS. Read currencies.TTF_GAS for the actual currency of the quote.
Dropping the unit: Always document EUR/MWh in your stored records. This prevents silent mismatches when joining with positions measured in different units.
Parsing by position: Never assume the order of JSON keys; always access by explicit field name, e.g., rates["TTF_GAS"].
Overwriting historical snapshots: If dates.TTF_GAS has not changed, treat the quote as the same-day value and retain your prior snapshot unless your controls detect a revised publish.
