Xeronance Realtime Market Data (BIST, VIOP, FX, Crypto)

Xeronance Realtime Market Data

Real-time quotes for Borsa Istanbul (BIST), VIOP derivatives, FX pairs, precious metals, commodities, CFDs and crypto — roughly 2,070 instruments in one Actor.

No 15-minute delay. No conflation. No snapshot-every-N-seconds. A quote is published the moment the price changes.

Why this Actor exists

Turkish market data is badly served. Google Finance is unreliable for BIST, most global APIs delay quotes by 15 minutes, and many skip the Turkish market entirely. We built this feed for our own trading systems and opened it up.

Prices come straight from a professional terminal feed — not from a delayed aggregator and not scraped from a website.

Try it right now

The Actor comes with a demo key already filled in — just hit Start. No signup, no card, nothing to configure.

The demo key is limited to 5 symbols per request, which is enough to see the data flowing but not enough for production.

Getting your own key

👉 t.me/xeronancebot — send /start, pick a plan, receive your key. Takes under a minute.

Input

Field	Type	Description
apiKey	string	Your Xeronance API key (starts with XR_live_)
symbols	array	Symbols to fetch. Case-insensitive.
pollSeconds	integer	0 = single snapshot, then exit. Positive = repeat at this interval.
maxIterations	integer	How many rounds in polling mode. 0 = unlimited.

{
  "apiKey": "XR_live_...",
  "symbols": ["GARAN", "THYAO", "EURUSD", "XAUUSD", "BTCUSDT:BNN"],
  "pollSeconds": 0,
  "maxIterations": 0
}

Snapshot vs. continuous

• pollSeconds: 0 — fetch once, write the dataset, exit. Cheapest option; ideal for a scheduled task that runs every N minutes.
• pollSeconds: 60 — keep running and collect every minute. Use with maxIterations to bound the run.

For sub-second updates, use the WebSocket endpoint directly rather than this Actor — Apify Actors are not designed for continuous streaming.

digits	Number of decimal places for this instrument
quotedAt	When the price was set (ISO-8601, +03:00)
quotedAtMs	Same, Unix milliseconds

Behaviour worth knowing

Situation	What happens
Symbol exists but has not traded today	Row is returned with bid/ask null
bid and ask are equal	By design. The feed publishes the last traded price on both sides so you can apply your own spread.
Symbol does not exist	Skipped, logged as a warning, run still succeeds
Duplicate symbols in input	Deduplicated; they do not count against your plan limit
Plan symbol limit exceeded	Request rejected with a clear error naming your plan
Quota exhausted	Actor waits for the interval the API returns, then retries

Symbols are fetched in batches of 50, so 200 symbols cost 4 API requests, not 200.

Plans

Plan	Price	Symbols per request	Requests/day	Requests/min
Free	$0	10	200	60
Basic	$19/mo	50	10,000	120
Pro	$49/mo	200	100,000	600
Diamond	$149/mo	2,500 (all)	unlimited	3,000

Annual billing: pay for 10 months, get 12.

Quotas reset at midnight Europe/Istanbul. Every API response carries X-RateLimit-* headers so you can track usage before hitting a limit.

Diamond has no daily cap; the per-minute ceiling exists purely as abuse protection and no normal workload comes close to it.
