# Delx Implied From Yes/No

> Delx Implied From Yes/No is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Converts raw yes/no vote counts into implied probabilities, returning calibrated p_yes and p_no with overround disclosure.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-implied-from-yes-no-a1179201 -d '<json body>'
```

Example prompt: I have 52 'yes' votes and 74 'no' votes from a poll — can you calculate the implied probability for each outcome and tell me the overround?

## When to prefer this

Use this endpoint when you have raw binary vote, odds, or count data and need normalized implied probabilities with explicit overround disclosure, particularly in prediction market, polling, or binary classification contexts where calibration and margin transparency matter.

## Known failure modes

- Missing or non-numeric yes/no values returns a validation error
- Both yes and no equal zero causes division-by-zero or undefined probability
- Negative input values may return an error or unexpected results
- Non-numeric strings in yes or no fields return a 400-level error

## How this service works

Normalize yes/no prices into implied probabilities. Call when two-sided prediction markets quoted as separate yes and no. Returns normalized yes/no probs 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

A JSON object with p_yes (float), p_no (float), schema identifier string ('delx/util-implied-from-yes-no/v1'), and overround (float representing the total probability excess above 1.0, indicating implied market margin).
