Code of Paper CLI

Discover GitHub implementations of research papers — from the terminal.

Search 181k+ arXiv papers and find their code on GitHub. Works for humans and AI agents alike.

Install

pip install codeofpaper

Or with pipx for isolated installs:

pipx install codeofpaper

Requires Python 3.10+. No API key needed — works anonymously at 60 requests/minute.

Quick Start

# Search for papers
codeofpaper search "vision transformers"

# Get paper details (arXiv IDs or full URLs both work)
codeofpaper paper 2010.11929
codeofpaper paper https://arxiv.org/abs/2010.11929

# Find code implementations
codeofpaper code 1706.03762

# Browse trending papers with code
codeofpaper trending --has-code

# JSON output for scripts and agents
codeofpaper -o json trending | jq '.trending[] | {title, stars: .max_stars}'

# One-shot reproducibility context for an agent: paper + confident repos
# (with tier + framework + license) + fork-graph in a single JSON payload.
codeofpaper -o json paper 2010.11929 | jq '{title, repos: [.repos[] | {full_name, tier}], forks: [.fork_graph[] | .full_name]}'

# Literature review in one command
codeofpaper research "reinforcement learning" --depth deep

Output Formats

Use -o / --output before the subcommand:

codeofpaper -o json paper 2010.11929
codeofpaper -o quiet search "attention" | head -5
codeofpaper -o csv trending --has-code > papers.csv

Format	Flag	Use case
Table	-o table	Human reading (default)
JSON	-o json	Scripts, jq pipelines, full response data
Quiet	-o quiet	IDs only, one per line — pipe into other commands
JSONL	-o jsonl	Streaming, append to files, batch processing
BibTeX	-o bibtex	Citation managers, LaTeX bibliographies
CSV	-o csv	Spreadsheets, pandas, data analysis

The shorthand -q is equivalent to -o quiet:

codeofpaper -q search "transformers" | head -3

You can set a default format via config so you don't need -o every time:

codeofpaper auth setup    # then edit ~/.config/codeofpaper/config.json
