Professional solutions
GreyhoundAPI is built by a team of algorithmic traders. We design, build and run automated systems across Betfair, Smarkets, Matchbook and BETDAQ — the same models and infrastructure we run ourselves. If you have an edge and need it engineered into a live, reliable system, we take you from idea to production.
Working across the major exchanges
What we do
Twelve of the things teams come to us for. Most projects touch several — we join them into one system that runs without you having to watch it.
Streaming prices and order placement across Betfair, Smarkets, Matchbook and BETDAQ, behind one clean interface.
Order-management engines that place, hedge and manage positions at machine speed, with your rules enforced.
Reading the book — liquidity, overround, price formation and where the real edges actually sit.
Turning your ideas into fair-value models and tested signals, from research through to production.
Replaying historical markets to prove a strategy holds up before anything is at stake.
Low-latency ingestion, normalisation and storage, so your models always see the live picture.
Position limits, kill-switches and live exposure monitoring that keep an automated book safe.
Splitting and balancing positions across selections and venues automatically, to a target you set.
Tuned, well-placed deployments for the strategies where milliseconds decide the outcome.
Live P&L, position and health dashboards, with alerts the moment something drifts.
Hardened servers, systemd services and uptime monitoring — the unglamorous part, done right.
Getting an idea off the ground fast — a working prototype you can evaluate in days, not months.
How we build
Research in one place, execution in another, dashboards in a third — we reach for the tool that fits the job, not the fashion. A sample of what we work in day to day:
Why us
We're not a consultancy that read about these markets — we trade them. The data behind this API feeds our own systems, and the systems we build for clients are the ones we'd be happy to run ourselves: reliable, monitored, and honest about where the edge is and isn't.
Bring an idea, a half-built bot, or a spreadsheet that already works. We'll help you turn it into something that runs on its own — and stays running.
Rates & engagement
Every project is scoped properly on a call, but here's the shape of it. Drag to see an indicative day-rate range — the final number depends on what you actually need.
Indicative day-rate estimate only. Fixed-scope quotes and retainers are agreed on the call.
from $250
A focused session — a code review, a second opinion on an approach, or a sounding board before you commit.
from $4,000
A fixed-scope build with a clear deliverable and timeline — a prototype, an exchange connector, a strategy harness.
from $3,500/mo
Ongoing development and operations — we run, monitor and evolve the system alongside you.
