What is kestrel.markets
The managed platform for Kestrel — the language for agentic trading.
kestrel.markets is the managed platform for Kestrel,
the open-source language and runtime for agentic trading — published on npm as
kestrel.markets, MIT-licensed, with the full source, the examples, and the
language ADRs shipped in the package. Kestrel gives you four
kinds of statement — View, Wake, Plan, Grade. The platform runs
them for you: licensed data, authority, deterministic execution, and signed
evidence. Your agent brings the intelligence; the platform never hosts it.
Start with a free sim
No signup, no API key, no payment before first value — mint an anonymous trial capability and run a real deterministic sim:
curl -sS -X POST https://api.kestrel.markets/capabilities/trialThe trial capability is anonymous and rate-limited, but the execution path is the real deterministic one — fail-closed parsing, certified outputs. The Quickstart takes you from this call to a certified, shareable proof URL in four requests.
