Hash Generator API

Cryptographic hash generator supporting MD5, SHA1, SHA256, SHA512, and bcrypt. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

{
  "mcpServers": {
    "hash-generator": {
      "url": "https://hash-generator.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl -X POST "https://hash-generator.api.klymax402.com/api/hash" \
  -H "Content-Type: application/json" \
  -d '{"text":"..."}'
# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

crypto_generate_hash

Use this when you need to generate a cryptographic hash of text. Supports md5, sha1, sha256, sha512, and bcrypt algorithms. Returns the hash string, algorithm used, and hash length. Do NOT use for password strength checking — use security_check_password. Do NOT use for data validation — use data_validate_json.
