ONE Engine Batch Hash API
x402
ONE Engine Batch Hash API is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0011/call, status unknown (last checked 2026-10-02).
Computes SHA-256 or SHA-512 cryptographic hashes for up to 100 UTF-8 strings in a single pay-per-call request.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with the algorithm used, the total count of hashed items, and a results array where each entry contains the index of the input string and its hex-encoded hash digest.
Example use cases
Deduplication fingerprinting pipeline
“I have a list of 50 text records and I want to deduplicate them — can you compute SHA-256 hashes for all of them so I can compare fingerprints and find duplicates?”
Content integrity verification
“Before I store these 10 config values, hash each one with SHA-512 so I can store the digests alongside them and verify integrity later.”
Agent-side token fingerprinting
“Hash these API key strings with SHA-256 so I can log their fingerprints without exposing the raw secrets: 'sk-abc123', 'sk-xyz789', 'sk-def456'.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/hash/batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to hash multiple strings in a single round-trip rather than calling a single-hash endpoint repeatedly. It is ideal for agents that need to fingerprint, deduplicate, or integrity-check batches of text data cheaply using standard SHA-256 or SHA-512 algorithms, billed at a flat $0.0011 USDC per call regardless of batch size up to 100 items.
Side effects
- Array exceeds 100 items — request rejected
- Invalid algorithm value (not sha256 or sha512) — validation error
- Non-UTF-8 or malformed string input — parsing error
- Payment failure via x402 — 402 response before processing
- Empty items array — may return empty results or validation error
