    "Content-Type": "application/json"
  },
  body: JSON.stringify({
      "input": "The quick brown fox jumps over the lazy dog"

Response

The result sits under data in the standard envelope. See the response format guide for errors and status codes.

returns

data.hash: The hex digest of your input.
data.algorithm: Algorithm used, sha256 by default.
data.hash_length: Length of the digest in hex characters.
data.input_length: Length of your input in bytes.

Authentication and limits

This endpoint needs an API key. Use the sandbox ("try it" above) to test it without registering. See the authentication guide for details.

Standard rate limits apply to this endpoint.

Common use cases

File integrity verification

Generate SHA256 hashes of files to verify integrity after transfer or storage. Detect tampering or corruption.

Data deduplication

Hash content to create unique fingerprints for deduplication. Identify duplicate entries in databases or file systems efficiently.

Checksum generation for APIs

Generate request or response checksums for API integrity verification. Ensure data hasn't been modified in transit.
