AgentResolver Hash & Encode
x402
AgentResolver Hash & Encode is a paid API for AI agents from agentresolver.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-01).
Performs cryptographic hashing and encoding operations (SHA-256, SHA-512, HMAC-SHA256, Base64 encode/decode, JWT decode) on a given string input.

How this service works
Deterministic hashing and encoding primitive for SHA-256, SHA-512, HMAC-SHA256, Base64 encode/decode, and non-verifying JWT decode.
Output
Returns the result of the requested cryptographic or encoding operation as a string — for example, a hex-encoded hash digest, a base64 string, a decoded plaintext, or a decoded JWT payload object.
Example use cases
Verify file integrity with SHA-256
“Hash the string 'my-config-file-content-abc123' using SHA-256 so I can verify its integrity later.”
Decode a JWT token payload
“I have this JWT token — can you decode it and show me what's in the payload? Here it is: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIn0.signature”
Generate HMAC for webhook verification
“Generate an HMAC-SHA256 of the string 'order_id=42&amount=99.99' using the secret key 'mysecretkey123' so I can sign my webhook payload.”
Technical details
Endpoint
GEThttps://agentresolver.vercel.app/api/hash-encode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs quick, serverless cryptographic hashing or encoding without standing up its own compute — especially for SHA-256/SHA-512 fingerprinting, HMAC signing for webhook payloads, base64 encode/decode, or inspecting JWT payloads. Ideal for lightweight, single-call cryptographic operations within an agent workflow where local code execution is not available.
Side effects
- Missing required 'operation' field returns a validation error
- Unsupported operation value (outside the allowed enum) returns an error
- HMAC-SHA256 operation without a 'secret' field may return an error or empty result
- Invalid base64 input for base64-decode returns a decoding error
- Malformed JWT for jwt-decode returns a parse error
- Payment of 0.001 USDC required per call; missing or failed payment returns HTTP 402
