pastable-x402 Text Hashing
x402
pastable-x402 Text Hashing is a paid API for AI agents from pastable-x402.pages.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).
Hashes an input string using MD5, SHA-256, and SHA-512 simultaneously, returning all three digests plus byte length.

How this service works
Pay-per-call utility APIs for agents: EVM helpers (checksum, unit conversion, keccak), data transforms (CSV to JSON, JSON diff, URL canonicalisation), text tools (hashing, JWT decode), and Bazaar market intelligence. x402 on Base mainnet.
Output
Returns a JSON object containing the MD5, SHA-256, and SHA-512 hex-encoded digests of the input string, plus the byte length of the input. All three hash algorithms are computed in a single call.
Example use cases
Verify downloaded file integrity
“I have the text content of a file I just downloaded — can you hash it with SHA-256 using UTF-8 encoding so I can compare it against the checksum the server published?”
Generate content fingerprint for deduplication
“Hash this article text in UTF-8 so I can use the SHA-256 digest as a unique fingerprint to detect duplicates in my database.”
Hash a base64-encoded payload
“I've got a base64-encoded blob I need to checksum — can you run it through the hashing endpoint with base64 encoding and return me the MD5 and SHA-256?”
Technical details
Endpoint
GEThttps://pastable-x402.pages.dev/text/hashWhen to prefer
Choose this endpoint when you need multiple hash algorithms (MD5, SHA-256, SHA-512) computed simultaneously in a single paid call, saving round-trips compared to separate hashing APIs. Ideal for agents that need to fingerprint, deduplicate, or verify text content and want all common digest formats at once. The x402 micropayment model ($0.02 USDC) makes it suitable for per-operation billing in automated pipelines without subscriptions.
Side effects
- Missing required query parameters 'data' or 'encoding' returns an error
- Invalid encoding value (not utf8, base64, or hex) causes a bad request
- Payment not completed via x402/Base mainnet results in 402 Payment Required
- Malformed base64 or hex input string causes a processing error
- Network timeout on the Cloudflare Pages edge function
