Quick Start

MMseqs2 — Python Examplepython
import requests

API_KEY = "sk-sci-your-key-here"
url = "https://scirouter.ai/v1/proteins/search"

response = requests.post(url, json={
    "sequence": "MKFLILLFNILCLFPVLAADNHGVS...",
    "database": "swissprot",
    "max_hits": 10
}, headers={"Authorization": f"Bearer {API_KEY}"})

hits = response.json()["hits"]
for hit in hits:
    print(f"{hit['accession']}: {hit['identity']:.1f}% "
          f"(E={hit['evalue']:.1e})")

Use Cases

1
