Query ARCHS4 REST API for uniformly processed RNA-seq expression, tissue patterns, co-expression across 1M+ human/mouse samples. Retrieve z-scores, co-expressed genes, samples by metadata, HDF5 matrices. For variant population genetics use gnomad-database; for pathway enrichment use gget-genomic-databases (Enrichr).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ARCHS4 Database

## Overview

ARCHS4 (All RNA-seq and ChIP-seq Sample and Signature Search) is a resource of uniformly aligned and processed human and mouse RNA-seq data from NCBI GEO and SRA, covering 1 million+ samples. The REST API at `https://maayanlab.cloud/archs4/api/` provides gene-level expression profiles, z-score normalized tissue expression, co-expression networks, and sample metadata search — all without authentication. Large-scale bulk queries can also use the downloadable HDF5 expression matrices.

## When to Use

- Retrieving tissue-specific or cell-type-specific expression z-scores for a gene of interest across hundreds of tissue types
- Finding genes co-expressed with a query gene (co-expression network construction or guilt-by-association analysis)
- Searching for RNA-seq samples by tissue, disease, or metadata keyword to identify candidate datasets for reanalysis
- Comparing expression profiles of multiple genes across tissues to prioritize candidates for wet-lab follow-up
- Accessing uniformly processed gene expression matrices (HDF5 format) for large-scale cross-study analysis

How to install

The exact contents, by fingerprint
mdr add jaechang-hits/sciagent-skills/archs4-database@sha256:885f83e0664d091f

The line at the top of this page pins the label git:20260827.cbbeb75, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
