JSON Pointer Escape
x402
JSON Pointer Escape is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Escapes a single JSON Pointer reference token by applying RFC 6901 escaping rules (~0 and ~1 substitutions) to a caller-supplied string.

How this service works
JSON Pointer Escape: JSON Pointer Escape escapes one JSON Pointer reference token from bounded caller-supplied values without an external provider. Call JSON Pointer Escape 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 Pointer Escape as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-part…
Output
Returns a versioned deterministic JSON object containing the escaped token string, normalized values, transformation counts indicating how many substitutions were made, and a versioned result contract — all processed in memory without data retention.
Example use cases
Escaping slashes in field names
“I have a JSON field name called 'a/b/c' that I need to use inside a JSON Pointer path — can you escape it so the slashes become valid reference token characters?”
Sanitizing tilde characters before pointer construction
“Before I pass this field name 'price~discount' to the downstream tool as part of a JSON Pointer, can you escape it so the tilde is properly encoded as ~0?”
Normalizing user-supplied key for JSON Pointer use
“A user submitted the key 'product~1/variant' and I need to embed it in a JSON Pointer reference path — please escape it according to RFC 6901 so tildes become ~0 and slashes become ~1.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-pointer-escapeWhen to prefer
Use this endpoint when an AI agent needs to safely encode a single string as a JSON Pointer reference token (per RFC 6901) before constructing or passing a JSON Pointer path to a downstream tool. Prefer it over ad-hoc string replacement when you need a versioned, deterministic result contract with transformation counts for auditing or debugging. Ideal as a pre-processing step in agentic pipelines that assemble JSON Pointer expressions from user-supplied or dynamic field names.
Side effects
- Token exceeds 8192 character limit — request rejected
- Malformed request body — missing or invalid token field
- Payment failure via x402 — call not executed
- Upstream timeout or service unavailability — 5xx error returned
