Delx Commerce Fingerprint Lite
x402
Delx Commerce Fingerprint Lite is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Generates a compact 16-character SHA-256 fingerprint (hash) of an input text string for lightweight deduplication or identity checks.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing a schema identifier ('delx/util-fingerprint-lite/v1'), the hashing algorithm used ('sha256-16'), and a 16-character hexadecimal fingerprint of the input text (e.g. '1d6334fef87552e1'). The fingerprint is deterministic — identical inputs always produce identical outputs.
Example use cases
Deduplicating agent memory entries
“I have a bunch of text snippets being stored by my agent and I want to avoid saving duplicates — can you generate a short fingerprint for this one: 'Meeting notes from Monday: discussed Q3 targets and headcount'?”
Cache key generation for LLM responses
“I want to use a short hash as a cache key for this prompt text so I don't re-run expensive LLM calls — can you fingerprint: 'Summarize the latest news about electric vehicles in three bullet points'?”
Content integrity check before processing
“Before my pipeline processes this user-submitted content, I need a quick fingerprint to track it: 'User feedback: the onboarding flow is confusing and takes too long.' Can you generate a hash for it?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/fingerprint-lite?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.001 USDC), deterministic short hash of text for deduplication, caching, or lightweight content tracking — without needing full cryptographic security or collision resistance. It is ideal for agent pipelines that process high volumes of text and need no-signup, pay-per-result fingerprinting via x402 on Base or Solana.
Side effects
- Missing or empty 'text' field returns an error
- Extremely long text inputs may be rejected or truncated
- Payment failure (insufficient USDC balance) results in a 402 response before processing
- Network timeout if the service is temporarily unavailable
