How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing the pruned input object (with null-valued keys removed), the list of removed key names, the operation schema identifier, a status of 'pass', and verifiable evidence including a SHA-256 hash of the input and confirmation that no external calls were made and data was not retained.
Example use cases
Clean API response before processing
“I'm getting a JSON response from an upstream API that has a bunch of null fields cluttering it up — like {"id": 42, "name": "Alice", "email": null, "phone": null}. Can you strip out all the null keys and tell me which ones were removed?”
Sanitize webhook payload for storage
“Before I store this webhook payload, I want to remove any null fields so my database doesn't have sparse records. Here's the object: {"event": "purchase", "user_id": 99, "coupon": null, "referral": null, "amount": 49.99}. Prune the nulls for me.”
Compact config object for agent handoff
“I'm passing a config object to another agent step but I want to remove any null options first so it only sees the active settings. Object is {"timeout": 30, "retries": null, "endpoint": "https://example.com", "auth": null}. Remove the null keys and give me the clean version.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-null-prune?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, verifiable, pay-per-call utility to strip null fields from a JSON object without managing infrastructure or signing up for a service. Ideal for AI agents that need trustless, auditable data cleaning with cryptographic evidence of processing. Prefer this over custom code when you need a consistent, versioned operation schema with no data retention guarantees baked into the response.
Side effects
- Object exceeds 128 properties — request rejected
- Malformed or non-object input — schema validation error
- Network or payment failure via x402 protocol — no result returned
- Empty object input — returns unchanged empty object with no removed keys
