How this service works
Call when an agent needs a md5 digest of text, encoded as base64url. No network and no LLM. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/digest-md5-base64url first.
Output
A JSON response containing the base64url-encoded MD5 digest of the input text. The output uses URL-safe base64 characters (replacing + with - and / with _, and omitting padding =), making it safe to embed directly in URLs, filenames, or HTTP headers.
Example use cases
URL-safe checksum for file deduplication
“I have the string 'invoice-2024-Q1-final.pdf' and I need its MD5 hash in base64url format so I can use it as a URL-safe cache key — can you compute that for me?”
Data integrity fingerprint for API payload
“Generate an MD5 digest of this JSON string '{"order_id":12345,"amount":99.99}' encoded as base64url so I can embed it in the request URL as an integrity check.”
ETag generation for HTTP caching
“I need a base64url-encoded MD5 hash of the text 'user-profile-data-v3' to use as an ETag value in my HTTP response headers — can you compute it?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-md5-base64url?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need an MD5 hash encoded in base64url (URL-safe, no padding) rather than hex or plain base64. Use it when the digest will be embedded in a URL, filename, or HTTP header where standard base64 padding characters would be problematic. Prefer the free sandbox endpoint (/v1/sandbox/digest-md5-base64url) for development/testing; use this paid endpoint for production workloads requiring guaranteed availability.
Side effects
- Missing or empty 'text' field returns a 400 validation error
- Text exceeding 100,000 characters returns a 400 or 413 error
- Missing or invalid API key returns a 401 unauthorized error
- Payment of $0.003 USDC not provided or rejected returns a 402 Payment Required
- Malformed request body returns a 400 bad request error
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. |
