x402
BLAKE2b Hash Function API is a paid API for AI agents from lin-desk-x402.lindesk.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).
Computes a BLAKE2b cryptographic hash of any input text, returning a hex digest of configurable length

How this service works
Pay-per-call API for AI agents: turn any public web page or PDF into clean, LLM-ready Markdown. $0.002 per call in USDC on Base via x402. No API key, no signup.
Output
Returns a JSON object with the operation name ('blake2b'), metadata including input character count, output character count, and elapsed milliseconds, plus the hex-encoded BLAKE2b hash digest as a string.
Example use cases
Deduplicate text content by fingerprint
“I have this product description text and I want to generate a BLAKE2b hash so I can quickly check if it already exists in my database — can you hash it with a 32-byte digest?”
Generate short content checksum
“Can you compute a 16-byte BLAKE2b hash of this JSON string so I can use it as a compact content fingerprint?”
Verify data integrity token
“Hash this API response payload using BLAKE2b with a 64-byte digest so I can compare it against the checksum the server sent me.”
Technical details
Endpoint
GEThttps://lin-desk-x402.lindesk.workers.dev/v1/texttools/blake2b?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call BLAKE2b hash with no API key or account setup, especially in agentic workflows using x402 micropayments on Base. Prefer BLAKE2b over MD5 or SHA-1 when you need a modern, collision-resistant hash; prefer this endpoint over self-hosted solutions when you want zero-infrastructure overhead in an agent pipeline.
Side effects
- Input text exceeds 100 KiB limit — request rejected
- Invalid digest_size value outside 1–64 range — returns error
- Non-integer or non-numeric digest_size string — schema validation failure
- Missing required 'input' query parameter — 400 bad request
- Payment not completed via x402 protocol — 402 Payment Required before response is returned
