How this service works
Return hash digest and byte size for caller-held content — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that already conver…
Output
A deterministic JSON object containing the hash digest of the input content computed with the specified algorithm, the byte size of the content, and the algorithm name used — suitable for integrity verification, deduplication, or preflight checks.
Example use cases
Preflight content integrity check
“Before I store this document chunk, hash it with SHA256 so I can detect tampering later — the content is: 'User agreement version 3.1 effective January 2025.'”
Pipeline deduplication fingerprint
“I need a deterministic fingerprint for this string using MD5 so I can deduplicate records in my pipeline: 'order_id=7821 customer=jane amount=49.99'”
Byte size audit for a text payload
“What's the byte size and hash of this JSON string? Use SHA256: '{"event":"click","userId":"abc123","timestamp":1700000000}'”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/checksum-metaWhen to prefer
Choose this endpoint when you need a lightweight, stateless, deterministic hash and byte-size computation for caller-held content without any external calls or data retention — ideal for agent preflight checks, pipeline deduplication, or integrity verification where privacy and reproducibility matter.
Side effects
- Missing or empty content field returns an error
- Unsupported algorithm value causes a validation error
- Malformed JSON request body returns 400
- Payment not included or insufficient USDC results in 402 response
