Hash Text (MD5 / SHA-1 / SHA-256 / SHA-512)
x402
Hash Text (MD5 / SHA-1 / SHA-256 / SHA-512) is a paid API for AI agents from x402.agentindex.world, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).
Computes a hex digest of any text string using a chosen algorithm: MD5, SHA-1, SHA-256, or SHA-512.

How this service works
Compute an MD5, SHA-1, SHA-256 or SHA-512 hex digest of text.
Output
Returns the hex-encoded digest of the provided text using the requested algorithm (md5, sha1, sha256, or sha512). The response is a deterministic fixed-length hex string: 32 chars for MD5, 40 for SHA-1, 64 for SHA-256, 128 for SHA-512.
Example use cases
Integrity check before file upload
“Take this file contents string and compute its SHA-256 hex digest so I can verify integrity on the other end: 'user_data_export_20240601_fullbackup'.”
Deduplication fingerprint for cache keys
“I need an MD5 hash of this URL query string to use as a cache key — hash 'search?q=bitcoin+price&lang=en&page=2' with md5.”
Password hashing for audit log
“Hash the string 'MyS3cr3tP@ssw0rd!' using SHA-512 so I can store a non-reversible fingerprint in the audit log.”
Technical details
Endpoint
GEThttps://x402.agentindex.world/hash/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call hash of a text string without managing a local crypto library or runtime environment. Ideal for serverless agents, sandboxed environments, or workflows where installing cryptographic dependencies is impractical. Supports four standard algorithms in a single endpoint, making it versatile for checksums, cache keys, integrity verification, or fingerprinting tasks.
Side effects
- Missing 'text' parameter — returns 400 or validation error
- Invalid 'algorithm' value not matching the enum (md5|sha1|sha256|sha512) — returns 400 validation error
- Empty text string may return empty-string hash (algorithm-dependent behavior)
- Network timeout or service unavailability — no hash returned
- Payment failure via x402 — endpoint returns 402 Payment Required
