# 2s.io GitHub Repository Language Breakdown

> 2s.io GitHub Repository Language Breakdown is a paid API for AI agents from 2s.io, paid per call via x402, $0.0025/call, status unknown (last checked 2026-09-14).

Returns the programming-language composition of a GitHub repository, including byte count and percentage share for each language, sorted by size.

## 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 2s-io-github-repository-language-breakdown-ad9f27a1
```

Example prompt: What programming languages make up the vercel/next.js GitHub repository, and what percentage of the code is each language?

## When to prefer this

Use this endpoint when you need a quick, structured, pay-per-call breakdown of programming languages in any public GitHub repository without setting up GitHub API credentials. Ideal for agents doing tech-stack discovery, repository analysis, or developer tooling workflows.

## Known failure modes

- Repository not found (invalid owner or repo name returns 404 or empty result)
- Repository is empty or has no detectable language content
- Rate limiting or upstream GitHub API unavailability
- Malformed query parameters (missing owner or repo) returns validation error

## How this service works

Programming-language breakdown of a repository: each language with its byte count and percentage of the codebase, sorted by size. Read-only; no caller key needed.

## Output

A list of programming languages used in the specified GitHub repository, each with its total byte count and percentage share of the overall codebase, sorted from largest to smallest contribution.
