## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-odds-decimal-to-probability-3fcbfbc8 -d '<json body>'
```

Example prompt: What's the implied probability for decimal odds of 2.5?

## When to prefer this

Use this endpoint when you need a fast, reliable micro-computation to convert a single decimal odds value to implied probability within an agent workflow — for example, before computing expected value, comparing markets, or calibrating a prediction model. It is ideal when you want a governed, auditable service call rather than computing 1/odds inline, ensuring consistent handling and schema-versioned output.

## Known failure modes

- Missing or non-numeric odds value returns a validation error
- Odds value of zero or below one would produce mathematically invalid probabilities
- Malformed request body or wrong content type may return a 400 error

## How this service works

Convert decimal odds into implied probability (1/odds). Call when normalizing book odds into agent probability space. Returns implied probability from decimal odds as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

Returns a JSON object containing the original decimal odds, the computed implied probability as a decimal (e.g. 0.4 for odds of 2.5), and a schema identifier string 'delx/util-odds-decimal-to-prob/v1'.
