Professional solutions

We build the systems that
trade the exchanges.

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.

What we do

From connectivity to a live, monitored book.

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.

Exchange connectivity

Streaming prices and order placement across Betfair, Smarkets, Matchbook and BETDAQ, behind one clean interface.

Automated execution

Order-management engines that place, hedge and manage positions at machine speed, with your rules enforced.

Market microstructure

Reading the book — liquidity, overround, price formation and where the real edges actually sit.

Models & signals

Turning your ideas into fair-value models and tested signals, from research through to production.

Backtesting & simulation

Replaying historical markets to prove a strategy holds up before anything is at stake.

Real-time pipelines

Low-latency ingestion, normalisation and storage, so your models always see the live picture.

Risk & exposure controls

Position limits, kill-switches and live exposure monitoring that keep an automated book safe.

Dutching & hedging

Splitting and balancing positions across selections and venues automatically, to a target you set.

Latency-aware infrastructure

Tuned, well-placed deployments for the strategies where milliseconds decide the outcome.

Dashboards & monitoring

Live P&L, position and health dashboards, with alerts the moment something drifts.

Deployment & ops

Hardened servers, systemd services and uptime monitoring — the unglamorous part, done right.

Rapid prototyping

Getting an idea off the ground fast — a working prototype you can evaluate in days, not months.

How we build

The right language for each layer.

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 run this ourselves.

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

Flexible ways to work together.

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.

1 day40 days

Indicative day-rate estimate only. Fixed-scope quotes and retainers are agreed on the call.

Advisory

from $250

A focused session — a code review, a second opinion on an approach, or a sounding board before you commit.

Project sprint

from $4,000

A fixed-scope build with a clear deliverable and timeline — a prototype, an exchange connector, a strategy harness.

Retainer

from $3,500/mo

Ongoing development and operations — we run, monitor and evolve the system alongside you.
