Probability. Confidence. Evidence.
Calibrated probabilities your agents can reason about. The evidence behind every call. The same record the dashboard quotes, exposed as four HTTP routes.
Built for agents and enterprise integrators.
The same calibrated forecast a person sees in the dashboard. Every response carries a probability, the evidence behind it, and a confidence interval an agent can reason about.
Four routes. One record.
Every response carries the probability, the confidence, and the evidence behind it.
GET/v1/forecast
Returns the current probability for a forecast subject, with the evidence chain attached. Which inputs moved, when, and by how much.
GET/v1/registry
Browse resolved forecasts with filters by subject, region, horizon, and date. Every entry has a resolution, a score, and the call’s history.
POST/v1/scenarios
Submit a scenario spec. Receive a probability distribution across branching outcomes. Useful for what-if reasoning before commitment.
GET/v1/calibration
Returns the public track record for any subject, region, or horizon. Machine-readable. The same record the dashboard quotes.
Preview to production. Four steps.
Each step is operator-led. Token rotation per your policy.

Hit the endpoints.
Any HTTP client works. Responses are typed JSON. The same forecast a person sees in the dashboard.
Move from preview to production.
Once your evaluation cycle closes. Every endpoint returns the evidence behind the probability, so an agent can reason about the result.
Why an API.
Agents need probabilities they can act on, not paragraphs of caveats. A narrative confidence does not survive a chain of model calls.
Meridian returns probability, confidence, and evidence behind every call. Same model as the dashboard. Same public record. Different surface.
Every call sits on the same public scale.
Hold-out backtests against decades of history. Brier scores rolling thirty days. Reliability decomposition machine-readable through /v1/calibration. The record the dashboard quotes is the same record the API exposes.
