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 escaped string (e.g. 'a~1b~0c' for input 'a/b~c'), along with processing metadata including a SHA-256 hash of the input, confirmation that no data was retained, and the count of external calls made (always 0). The response schema is 'delx/util-json-pointer-escape/v1' with a 'pass' status.
Example use cases
Safe JSON Pointer for nested key
“I have a JSON object with a key called 'user/profile' and I need to reference it using a JSON Pointer — can you escape that key so slashes and tildes are properly encoded for RFC 6901?”
Dynamic path segment encoding
“My agent is building a JSON Pointer path at runtime and one of the segments is '~config/base' — escape that token so it won't break the pointer syntax.”
Encoding API response field names
“I'm navigating a JSON document where a field is named 'a~1b/c' and I need to turn that into a valid JSON Pointer segment — can you apply the correct RFC 6901 escaping?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-pointer-escape?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiable, pay-per-use, no-signup utility for RFC 6901 JSON Pointer escaping — especially in agent workflows where auditability (SHA-256 input hash, no-retention evidence) matters. Prefer it over implementing the escaping inline when you need a tamper-evident proof of the transformation or when operating in a trust-minimized environment using USDC micropayments.
Side effects
- Input token exceeds 8192 character limit — rejected with a validation error
- Malformed JSON body — returns a 400-level error
- Payment not included or invalid x402 payment header — returns HTTP 402 Payment Required
- Network timeout if the service is temporarily unavailable
