SignalDesk AI SHA-256 Encoding
x402
SignalDesk AI SHA-256 Encoding is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).
Computes a SHA-256 hash of the provided text and returns it as a hexadecimal string

How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object containing 'hex' (the SHA-256 hash of the input text as a lowercase hexadecimal string, e.g. 'ba7816bf8f01cfea...') and 'algorithm' (the string 'SHA-256'). The response is deterministic — the same input always produces the same output.
Example use cases
Verify file or message integrity
“Hash the string 'invoice_2024_Q1.pdf:123456789bytes' with SHA-256 so I can compare it against a known checksum to confirm nothing was tampered with.”
Generate deterministic content ID
“Take the text 'user:alice@example.com|session:2024-06-01T12:00:00Z' and give me its SHA-256 hex hash so I can use it as a unique, reproducible identifier.”
Hash a password before storage comparison
“Give me the SHA-256 digest of the string 'MySecretPassword123!' so I can compare it against a stored hash during a manual audit.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/encoding/sha256?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pay-per-call, serverless SHA-256 hash via x402 micropayment without managing your own cryptographic infrastructure. Best suited for agents operating in the x402 payment ecosystem that need deterministic text fingerprinting at $0.001 per call. If you have native SHA-256 available in your runtime, prefer that over a paid API call.
Side effects
- Input text exceeds 4096 characters — request rejected with validation error
- Empty or missing 'text' field — may return error or hash of empty string
- Payment failure or insufficient USDC balance — 402 response blocking execution
- Service unavailability on Cloudflare Workers edge — 5xx error
