Hash Toolbox: MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256, CRC-32, Base64, and SRI
x402
Hash Toolbox: MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256, CRC-32, Base64, and SRI is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).
Computes every major hash algorithm (MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256, CRC-32, base64 SHA-256, and SRI strings) for a single text or hex input in one call.

How this service works
Every common hash of one input in a single call: MD5, SHA-1, SHA-256, SHA-384, SHA-512, Keccak-256 (Ethereum), CRC-32, base64 SHA-256, and Subresource Integrity strings (sha256-, sha384-, sha512-) for <script integrity>. Hashes UTF-8 text, or 0x/hex bytes with hex=true. Cheaper than hashing one algorithm at a time. Use for checksums, cache keys, file integrity and comparing digests across systems.
Output
Returns a JSON object containing: md5, sha1, sha256, sha384, sha512 (hex strings), keccak256 (hex string), crc32 (hex string), base64.sha256 (base64-encoded SHA-256), sri.sha256 / sri.sha384 / sri.sha512 (SRI integrity attribute strings prefixed with 'sha256-' etc.), and bytes (input byte count).
Example use cases
SRI hash for CDN script tag
“I need the subresource integrity strings for this JavaScript snippet so I can add an integrity attribute to my script tag — can you hash this text and give me the sha256-, sha384-, and sha512- SRI values? The text is: 'console.log("app loaded");'”
Ethereum Keccak-256 function selector
“What's the Keccak-256 hash of the string 'transfer(address,uint256)'? I need it to compute the Ethereum function selector.”
File integrity checksum bundle
“Generate all the common checksums for this file content — MD5, SHA-1, SHA-256, SHA-512, and CRC-32 — so I can publish them alongside my release: 'This is the release payload v2.4.1'”

Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/pack/hash-toolbox?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need multiple hash algorithms for the same input in a single call — it is cheaper and faster than calling separate hashing endpoints. Ideal for generating SRI strings for web assets, computing Ethereum Keccak-256 digests, building cache keys, publishing multi-algorithm checksums alongside releases, or comparing digests across systems. Prefer it over single-algorithm endpoints whenever you need more than one hash type.
Side effects
- Missing required 'text' parameter returns an error
- Input exceeding 100,000 characters may be rejected
- Invalid hex string when hex=true causes a parse error
- Network timeout or worker unavailability returns a 5xx error
- Payment failure (x402) if credits are exhausted
