How this service works
Call when an agent needs SHA-256 hex digests extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/regex-sha256 first.
Output
A JSON response containing a list of up to 20 SHA-256 hex digest strings found within the submitted text. If no SHA-256 hashes are present, an empty list is returned. Note: an empty match list is still billed at $0.005 USDC.
Example use cases
Extract hashes from security report
“I have a security advisory that lists several SHA-256 checksums mixed in with the prose — can you extract all the SHA-256 hashes from this text for me? Here it is: 'Affected binary hash: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855, see also 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824'”
Verify download checksums in pipeline
“After downloading these packages, I got this output from the installer log — please find all the SHA-256 hashes so I can verify them against the official manifest: 'Installed package foo-1.2 (sha256: a665a45920422f9d417e4867efdc4fb8a04a1f3fff1fa07e998e86f7f7a27ae3)'”
Audit container image digest list
“I've got the raw output from a Docker image inspection that contains a bunch of SHA-256 digests — can you pull out every SHA-256 hash from this text? 'sha256:abc123def456... layer digest: sha256:789feda012...'”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-sha256?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract SHA-256 hex digests from arbitrary text without running local code or regex. It is purely deterministic (no LLM, no network calls beyond the service itself), making it reliable and reproducible. Prefer the free sandbox endpoint POST /v1/sandbox/regex-sha256 for testing before incurring the $0.005 USDC charge. Choose this over general-purpose text extraction tools when you specifically need SHA-256 pattern matching with a known cap of 20 results.
Side effects
- Empty text input — rejected due to minLength:1 constraint
- Text exceeds 100,000 character limit — rejected
- More than 20 SHA-256 matches present — only first 20 returned, rest silently truncated
- No hashes found in text — returns empty list but still charges $0.005
- Payment failure — x402 payment not accepted, call blocked
- Network/service unavailability — HTTP 5xx response
