Simudyne

Simudyne is a London-based enterprise simulation software company that builds AI-powered, agent-based (multi-agent) simulation technology for financial services and other industries. Its platform spans Simudyne Horizon (automated model discovery, calibration, and validation), Simudyne Pulse (multi-agent market simulation), and Simudyne Nexus (reasoning environments for training and optimization). Its developer-facing product, Pulse, is a synthetic market data platform exposing a REST API and a Python SDK that deliver tick-level L1/L2 synthetic order book data, order events, and trades at millisecond resolution for backtesting, algo development, market-impact studies, pre-trade TCA, and ML/reinforcement-learning training. Simudyne also maintains classic Java/Scala agent-based modeling SDK starter projects and runs on Google Cloud, AWS, Oracle, Red Hat, and NVIDIA infrastructure.

Simudyne publishes 1 API on the APIs.io network. Tagged areas include Company, Simulation, Agent-Based Modeling, Synthetic Data, and Market Data.

Simudyne’s developer surface includes documentation, getting-started guide, signup flow, support, engineering blog, authentication, and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/simudyne: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
