API payload security kit

Fingerprint a request payload: content hash, HMAC signature with your shared key, and a CRC32 integrity checksum.

developer 3 steps 3 live tools

The chain

1. Content hash of the payload → hash-text
2. HMAC signature with the shared key → hmac
3. CRC32 integrity checksum → crc32

Run it

Fill the inputs and press Run — every step executes live and the JSON chain (each step's tool, args and result) appears here.

Or call it as an agent

curl -s https://wingmanprotocol.com/agents/templates/api-payload-security/run \
  -H 'Content-Type: application/json' \
  -d '{"payload": "{\"order\":1234,\"amount\":49.0}", "algorithm": "sha256", "key": "whsec_live_key"}'
