Delx JSON Merge Patch
x402
Delx JSON Merge Patch is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Applies bounded top-level JSON Merge Patch (RFC 7396) semantics to a target object using a patch object, returning the merged result as deterministic machine-readable JSON.

How this service works
Apply bounded top-level JSON Merge Patch semantics for integration planning. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible for authorizati…
Output
Returns a deterministic JSON object representing the result of applying the patch to the target using RFC 7396 JSON Merge Patch semantics — fields present in the patch overwrite or null-delete corresponding fields in the target, while unmentioned fields are preserved unchanged.
Example use cases
Config merge preflight before deploy
“Before we push this config update to production, apply this patch {"featureFlags": {"darkMode": true}, "timeout": null} to our current config {"featureFlags": {"darkMode": false}, "timeout": 30, "retries": 3} and show me exactly what the merged config would look like.”
Policy document delta preview
“We're updating our access policy — apply this patch {"allowedRoles": ["admin", "editor"], "deprecated": null} to the existing policy object {"allowedRoles": ["admin"], "deprecated": true, "version": 2} so I can review the result before committing it.”
Integration schema merge check
“I need to merge a partner's partial record update {"email": "new@example.com", "phone": null} onto our stored user object {"id": "u-99", "email": "old@example.com", "phone": "+15550001234", "tier": "gold"} — what does the final merged object look like?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-merge-patchWhen to prefer
Prefer this endpoint when you need a stateless, deterministic, zero-retention computation of JSON Merge Patch results as a preflight or dry-run step before committing changes in an enterprise or integration workflow. It is ideal when you want machine-readable merge output without involving your own runtime logic, when operating inside an agentic pipeline that pays per-call via x402 on Base, or when you need advisory merge results that keep your production system untouched. Choose alternatives if you need deep/recursive JSON Patch (RFC 6902 op arrays), schema validation beyond merging, or persistent storage of results.
Side effects
- Invalid or non-object JSON supplied for target or patch fields — returns error indicating malformed input
- Patch or target exceeds bounded size limits — may return rejection or truncation error
- Network or payment authorization failure via x402 — returns 402 or payment-related error
- Missing required fields (target or patch not provided) — returns schema validation error
