Agent402 UK Hash Digest
x402
Agent402 UK Hash Digest is a paid API for AI agents from agent402.co.uk, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Computes SHA-256, SHA-1, MD5, or SHA-512 hex digests of arbitrary UTF-8 text strings

How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
Returns a hex-encoded digest string corresponding to the chosen algorithm (sha256, sha1, md5, or sha512) applied to the provided UTF-8 input text.
Example use cases
Integrity check before data write
“Before I store this config blob, hash it with SHA-256 so I can compare it later and confirm nothing changed: 'host=db.prod.internal;port=5432;user=admin'”
Legacy MD5 fingerprint for API compatibility
“I need an MD5 hash of the string 'user:secret123' — the old system I'm integrating with expects MD5 fingerprints for its request signing.”
Mid-task deduplication check
“Hash these two strings with SHA-512 and tell me if they produce the same digest — I want to know if 'invoice_2024_v1' and 'invoice_2024_v1' are identical before processing them.”
Technical details
Endpoint
POSThttps://agent402.co.uk/v1/utils/hashWhen to prefer
Choose this endpoint when an AI agent needs a lightweight, on-demand cryptographic hash during a task — especially for integrity checks, deduplication, or fingerprinting text values — without needing a local hashing library. Particularly useful in agentic pipelines where the agent runtime lacks native crypto utilities or where consistent, auditable hashing via an external service is preferred.
Side effects
- Unsupported algorithm value returns an error — must be sha256, sha1, md5, or sha512
- Empty or missing text field may return a validation error
- Very large text inputs may time out or be rejected
- Non-UTF-8 encoded binary content may produce incorrect results
