x402-cent SHA-256 Text Hashing
x402
x402-cent SHA-256 Text Hashing is a paid API for AI agents from x402-cent.x402-cent.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).
Computes the SHA-256 hash of a UTF-8 encoded text string (up to 1024 bytes) for a fee of $0.01 USDC via x402 payment.

How this service works
SHA-256 of text encoded as UTF-8 (maximum 1024 bytes). Costs 0.01 USDC.
Output
The endpoint returns the SHA-256 hash of the submitted text as a hex-encoded digest string. The input text must be UTF-8 encoded and no longer than 1024 bytes.
Example use cases
Fingerprint a document excerpt
“Take this paragraph of text and give me its SHA-256 hash so I can use it as a unique fingerprint: 'The quick brown fox jumps over the lazy dog.'”
Verify data integrity before storage
“Hash this API key string 'sk-abc123xyz789' with SHA-256 so I can store the digest instead of the raw value.”
Generate checksum for audit log
“I need to generate a SHA-256 checksum for this log entry: 'user_id=42 action=login timestamp=2024-01-15T10:30:00Z' — can you hash it?”
Technical details
Endpoint
POSThttps://x402-cent.x402-cent.workers.dev/sha256?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, fast, pay-per-use SHA-256 hash of a short text string (≤1024 bytes) without managing cryptographic libraries yourself, or when operating in an environment where x402 micropayment-gated APIs are preferred. Ideal for one-off hashing tasks in agent workflows where spinning up local crypto is impractical.
Side effects
- Input text exceeds 1024 bytes — request rejected with size limit error
- Payment of 0.01 USDC not provided or invalid — request blocked by x402 payment gate
- Invalid UTF-8 encoding in the input body — parsing error returned
- Empty body submitted — may return an error or hash of empty string
- Network timeout on the Cloudflare Worker — transient failure
