Industrial Platform Web Tools – Checksum
x402
Industrial Platform Web Tools – Checksum is a paid API for AI agents from x402-gateway-production-1f21.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).
Computes a cryptographic checksum for arbitrary text or binary-encoded data, enabling data integrity verification over the x402 payment protocol.

How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON response containing the computed checksum or hash for the submitted data, along with a status field confirming the operation succeeded. The checksum serves as a deterministic fingerprint of the input.
Example use cases
Data integrity before file upload
“Before I upload this document text to storage, compute a checksum for it so I can verify nothing got corrupted in transit: 'Annual report Q4 2024: revenue was $4.2M...'”
Deduplication fingerprinting pipeline
“I'm building a deduplication pipeline — can you hash this content string so I can compare it against previously seen records? The data is: 'user_id:9821, event:purchase, item:SKU-4421'”
Tamper detection for audit logs
“Generate a checksum for this audit log entry so I can detect if it gets modified later: '2024-11-15T10:33:00Z admin deleted user account id=5521'”

Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/checksum?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a machine-payable, lightweight checksum or hash computation without setting up your own cryptographic infrastructure. Ideal for agents embedded in workflows that need on-demand, per-call integrity verification billed at $0.001 USDC via x402.
Side effects
- Data string exceeds 250,000 character limit — payload rejected
- Missing required 'data' field in body — validation error
- Invalid bodyType enum value — request rejected
- Network or payment authorization failure returns HTTP 402
