How this service works
JSON Object Lowercase Keys: JSON Object Lowercase Keys lowercases top-level keys and reports case collisions from bounded caller-supplied values without an external provider. Call JSON Object Lowercase Keys 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 Lowercase Keys as versioned deterministic JSON. Price:…
Output
Returns a versioned deterministic JSON object containing the transformed object with all top-level keys lowercased, a count of keys transformed, a list of any case collisions detected (where two or more original keys map to the same lowercase key), and normalized values conforming to a versioned result contract.
Example use cases
Normalize keys before strict downstream API
“Before sending this JSON payload to the payment processor, lowercase all its top-level keys and flag any collisions so nothing breaks: {"UserID": "abc123", "Amount": 50, "Currency": "USD"}.”
Detect case conflicts in merged data
“I merged two data sources and the combined object might have keys that differ only by capitalization — can you lowercase all the top-level keys and tell me which ones collide?”
Schema compliance for data pipeline
“Our data pipeline requires all incoming JSON keys to be lowercase — run this object through the key normalizer and report how many keys were changed and whether any collisions were found.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-object-lowercase-keysWhen to prefer
Choose this endpoint when an agent needs to programmatically normalize JSON object keys to lowercase before handing structured data to a downstream tool with a strict lowercase-key contract, or when you need to detect silent data-loss risks caused by case collisions (e.g. merging two datasets). It is fully deterministic, stateless, and requires no API key — ideal for lightweight in-pipeline normalization steps where reliability and auditability matter more than speed. Prefer alternatives only if you need deep or nested key normalization (this only handles top-level keys) or if you require full schema transformation beyond key casing.
Side effects
- Object exceeds 128 properties limit — rejected with validation error
- Input is not a valid JSON object — returns parse or type error
- Payment of 0.001 USDC not fulfilled — request blocked by x402 payment gate
- Key collision detected but not fatal — reported in collision list rather than error
- Empty object input — returns empty transformed object with zero counts
