Code Examples

cURL

curl "https://api-snap.com/api/hash?text=Hello+World&algorithm=sha256" \
  -H "Authorization: Bearer snp_your_key"
# {"hash":"a591a6d40bf420...","algorithm":"sha256","encoding":"hex"}

JavaScript

const res = await fetch(
  "https://api-snap.com/api/hash?text=verify-me&algorithm=sha512",
  { headers: { Authorization: "Bearer snp_your_key" } }
);
const { hash } = await res.json();

Python

import requests

r = requests.get(
    "https://api-snap.com/api/hash",
    params={"text": "Hello World", "algorithm": "sha3-256", "encoding": "base64"},
    headers={"Authorization": "Bearer snp_your_key"},
)
print(r.json()["hash"])

Common Use Cases
