Vextorium Hash & Encoding Utility

x402

Vextorium Hash & Encoding Utility is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.0045/call, status unknown (last checked 2026-10-19).

Computes cryptographic hashes, HMAC signatures, and encodes/decodes data in multiple formats (SHA-256, Keccak-256, MD5, Base64, Hex, Base58, JWT decode, UUID, etc.)

How this service works

232 pay-per-call data APIs for AI agents: official statistics and economy (ECB, Fed, Eurostat, World Bank, SEC, BOE, INE), crypto prices and sentiment, Spanish public data, compliance (sanctions, VAT, IBAN, LEI), science, weather, web and developer tools and local AI text tools. Pay in USDC via x402.

Output

A JSON object with the 'trade' field (operation name), 'result' field (the computed hash, encoded/decoded string, or UUID), and 'bytes_input' (number of bytes processed). For example: {"trade":"sha256","result":"ba7816bf...","bytes_input":3}.

Example use cases

Ethereum smart contract address verification

“Compute the Keccak-256 hash of this hex-encoded input '48656c6c6f' — the input is in hex format.”

HMAC signature for webhook validation

“Generate an HMAC-SHA256 signature for the message 'order:12345:confirmed' using the secret key 'mysecretkey123'.”

JWT token inspection

“Decode this JWT token for me so I can see the payload: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIn0.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c”

Technical details

Endpoint

POSThttps://api.vextorium.com/v1/hash?utm_source=zero.xyz

When to prefer

Use this endpoint when an agent needs to compute cryptographic hashes (SHA-256, Keccak-256, MD5), generate HMAC signatures, encode or decode data (Base64, Hex, Base58, URL encoding, Base64url), decode JWTs, or generate UUIDs — all in a single pay-per-call API supporting up to 1 MB input. Prefer over rolling your own crypto when you need a serverless, pay-as-you-go hashing utility especially in blockchain/DeFi pipelines where Keccak-256 is required.

Side effects

Missing required 'trade' field returns a validation error
Invalid base64 or hex input when input_format is set to those values causes a parse error
HMAC operations without a 'key' field may fail or return an error
Input exceeding 1 MB limit will be rejected
Invalid UUID namespace for uuid5 operation returns an error
Unsupported algorithm string for HMAC returns an error
Insufficient USDC balance causes payment failure before execution
