## How the API Works

A REST-friendly notation system for indexing real-world probabilities.

Previously known as "Odds and End—Point—s."

0.0000653 = 6.53 × 10⁻⁵ = /5/6

We encode each probability as `/n/m` where **n** is the negative exponent and **m** is the leading digit of the mantissa.

Σ

### Real Sources

Every probability backed by peer-reviewed papers, government data, or trusted institutions.

λ

### REST Notation

Clean /n/m paths that encode scientific notation for easy exploration and API access.

### Wide Spectrum

From coin flips (10⁻¹) to cosmic coincidences (10⁻⁶⁸) — the full range of rarity.
