x402
Delx Commerce JSON Patch Preview 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).
Applies a sequence of RFC 6902 JSON Patch operations to a document in-memory and returns the patched result with verifiable evidence, without persisting any data.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns the patched JSON document, a list of operations that were applied, a pass/fail status, the SHA-256 hash of the input for verifiability, a confirmation that no data was retained, and a count of external calls made (always 0). The schema identifier 'delx/util-json-patch-preview/v1' is included for auditability.
Example use cases
Validate config patch before deployment
“Before I push this config update, apply these JSON Patch operations to my current settings document {"timeout": 30, "retries": 3, "debug": false} — specifically replace /timeout with 60 and add /verbose as true — and show me what the patched config will look like.”
Dry-run API response transformation
“I want to preview what my API response object will look like after these patch operations: remove /deprecated_field and replace /version with 2. Here's the document: {"version": 1, "deprecated_field": "old", "name": "myService"}.”
Verify patch correctness in agent pipeline
“Check whether these JSON Patch ops — add /metadata/author with value 'alice' and replace /status with 'published' — applied to this document {"status": "draft", "metadata": {}} produce the right result, and give me the SHA-256 of the input so I can verify integrity.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-patch-preview?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a stateless, verifiable, pay-per-call JSON Patch preview with cryptographic evidence of the input (SHA-256) and a guarantee of no data retention — ideal for agents that need auditability or operate in zero-trust pipelines. Prefer it over rolling your own patch logic when you want a hosted, deterministic result with an immutable evidence trail and no signup friction.
Side effects
- Invalid or malformed JSON Patch operation format returns an error status
- Document exceeds 128 properties (maxProperties) causing rejection
- Operations array exceeds 256 items (maxItems) causing rejection
- Invalid JSON path in a patch operation leading to a failed apply
- Payment not included or insufficient USDC causing 402 response before processing
