How this service works
16-hex fingerprint of text via SHA-256 prefix. Call when you need short cache keys for agent content. Returns fingerprint hex for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
A 16-character hexadecimal string derived from the SHA-256 hash of the input text, usable as a compact, deterministic cache key or deduplication token. No data is retained server-side.
Example use cases
Cache key for agent responses
“I need a short cache key for this agent-generated summary so I can store and retrieve it efficiently — can you fingerprint this text: 'Q3 revenue grew 12% YoY driven by enterprise subscriptions'?”
Deduplicating repeated content
“I'm seeing duplicate entries in my pipeline — can you fingerprint each of these strings so I can compare them and detect repeats? Start with: 'User session initialized at 2024-01-15T09:00:00Z'”
Stable ID for indexed documents
“I need a stable, short identifier for this document chunk before I store it in my vector database — please fingerprint this text: 'Photosynthesis is the process by which plants convert light into energy.'”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/fingerprint-liteWhen to prefer
Choose this endpoint when you need a fast, cheap, stateless fingerprint of a text string for caching or deduplication, and you want a short 16-hex output rather than a full SHA-256 digest. Prefer it over full hashing libraries when your agent stack lacks local crypto utilities, or when you need a cost-effective ($0.001 USDC) on-chain-payable micro-operation with no key management or data retention concerns.
Side effects
- Empty or missing 'text' field returns an error
- Extremely large text inputs may be rejected or truncated
- Payment failure via x402 prevents execution
- Network timeout before hash is returned
