How this service works
Call when an agent needs a md5 digest of text, encoded as hex. No network and no LLM. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/digest-md5-hex first.
Output
Returns the MD5 hash of the provided text as a lowercase hexadecimal string (32 characters). The computation is deterministic, requires no network calls, and involves no LLM processing.
Example use cases
File content fingerprinting
“Hash this file's text content with MD5 and give me the hex string so I can check if it matches the expected checksum: 'The quick brown fox jumps over the lazy dog'”
Cache key generation
“Generate an MD5 hex digest for this query string so I can use it as a cache key: 'user_id=42&product_id=1337&locale=en-US'”
Data deduplication check
“What's the MD5 hex digest of this product description? I want to detect duplicates: 'Premium wireless noise-cancelling headphones with 30-hour battery life and foldable design.'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-md5-hex?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need a fast, deterministic MD5 hex digest of a text string without any network dependencies or LLM involvement. Use the free sandbox endpoint POST /v1/sandbox/digest-md5-hex first if available; fall back to this paid endpoint when the sandbox is unavailable or rate-limited. Choose this over SHA-based siblings when MD5 specifically is required (e.g. for legacy compatibility or interoperability with systems expecting MD5 checksums).
Side effects
- Missing or empty 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Missing or invalid API key results in authentication failure
- Payment of $0.001 USDC not fulfilled triggers 402 Payment Required
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| key | string | HMAC secret. Required on HMAC SKUs. Omit it for plain digests and checksums. The key is not stored. |
| text | string | Message to digest. For raw-hex SKUs this is hex bytes; for utf16 or latin1 SKUs it is decoded with that encoding. Otherwise it is UTF-8 text. |
