How this service works
JSON Object Omit: JSON Object Omit removes selected top-level keys from one JSON object from bounded caller-supplied values without an external provider. Call JSON Object Omit before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Object Omit as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-part…
Output
A versioned deterministic JSON response containing the filtered object with the specified top-level keys removed, along with counts of removed keys, normalized values, and a versioned result contract describing the transformation applied.
Example use cases
Strip sensitive fields before forwarding
“I have a JSON object from our internal API that includes 'apiKey', 'secretToken', and 'internalUserId' — can you remove those three keys before we pass the object to the third-party webhook?”
Trim payload to match strict downstream contract
“Our partner's API rejects any JSON with unknown fields. Take this object and omit the keys 'meta', 'debugInfo', and 'legacyField' so it only contains what their schema allows.”
Clean up structured plan before agent handoff
“Before handing this batch plan object to the execution agent, remove the keys 'planningNotes', 'draftVersion', and 'internalComments' — I only want the final operational fields to go through.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-object-omitWhen to prefer
Choose this endpoint when you need a deterministic, in-memory, stateless key-removal operation on a JSON object with no external dependencies, a versioned result contract, and a predictable cost of $0.001 USDC. Prefer it over custom code when operating in an agentic pipeline where auditability, bounded transformation counts, and a structured result envelope are important — especially before handing data to a downstream tool with a stricter schema contract.
Side effects
- Keys list exceeds 256 items — request rejected
- Object exceeds 128 top-level properties — request rejected
- Key strings exceed 8192 characters — request rejected
- Invalid JSON object supplied — validation error returned
- Payment of $0.001 USDC not provided or rejected — 402 response
- Requested keys not present in object — returns object unchanged with zero removal count
