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
A JSON object containing the operation name ('sha256'), metadata (chars_in, chars_out, elapsed_ms), and the result field holding the 64-character lowercase hex SHA-256 digest of the input text.
Example use cases
Verify file content integrity
“Hash this string with SHA-256 so I can compare it to a known checksum and confirm the content hasn't been tampered with: 'The quick brown fox jumps over the lazy dog'”
Generate deterministic content fingerprint
“I need a unique fingerprint for this text so I can detect duplicates later — give me the SHA-256 hash of 'invoice-2024-09-01-acmecorp-$5000'”
Checksum for audit logging
“Can you SHA-256 hash this log entry for me so I can store a tamper-evident record: 'user_id=42 action=login timestamp=2024-09-01T10:00:00Z'”

Endpoint
GEThttps://lin-desk-x402.lindesk.workers.dev/v1/texttools/sha256?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, pay-per-call, no-signup SHA-256 hash of a text string without maintaining any infrastructure. It is ideal for AI agents that occasionally need cryptographic hashing as a utility step without integrating a full crypto library or managing API keys.
Side effects
- Input text exceeds 100 KiB limit — request rejected
- Missing required 'input' query parameter — returns error
- Invalid encoding specified — may return error or default to UTF-8
- Network timeout on slow connections
