# GitHub Repository PR Merge Likelihood Predictor

> GitHub Repository PR Merge Likelihood Predictor is a paid API for AI agents from x402-api-24223879872.us-east1.run.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-11).

Predicts the likelihood that a GitHub repository will merge an AI-authored or external pull request, based on its AI/contribution policy and historical merge rate data.

## Facts

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 github-repository-pr-merge-likelihood-predictor-04fc6048
```

Example prompt: What are the chances my AI-authored PR would get merged into huggingface/transformers — does the repo have an AI contribution policy, and what's the historical external merge rate?

## When to prefer this

Use this endpoint when you need to programmatically assess whether a specific GitHub repository is receptive to AI-authored or external pull requests before investing time in a contribution. It is uniquely suited for agents that automate open-source contributions and need to triage repositories by their AI policy stance and historical merge behavior — something that cannot be determined from a simple GitHub API call alone.

## Known failure modes

- Invalid or non-existent repository slug returns an error or empty result
- Private repositories that are inaccessible to the crawler may return incomplete data
- Repos with very few external PRs will have low-confidence merge rate estimates
- Rate limiting or upstream GitHub API unavailability may cause transient failures
- Payment of $0.05 USDC required per call; insufficient balance or payment failure blocks the request

## How this service works

Predicts whether a GitHub repository will merge an AI-authored or external pull request, based on its stated AI/contribution policy and historical merge rates.

## Output

Returns a JSON object with a numeric merge likelihood score, an AI policy classification (forbidden/disclosure_required/allowed/unknown) with matching policy text snippets, external and member merge rates, bot-authored PR count, median hours to merge external PRs, last external merge timestamp, sample size used, whether the repo is archived, and any warning flags about the repository's contribution posture.
