Compute hash of any text using MD5, SHA-1, SHA-256, SHA-384, or SHA-512. Returns hex digest. For AI agents, integrity checks, deduplication, content addressing.

This endpoint speaks x402: an unpaid request returns HTTP 402 with machine-readable payment terms, your agent pays the $0.0022 USDC in USDC on-chain, and retries automatically. Pays to 0x4466d4A84b7c49a6A094ec6eef4a0712D6dd125e.

# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i "https://api.x402node.dev/dev/hash?algo=Algo (optional)&text=Input text (required)"

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
