# Delx Commerce JSON Pointer Unescape

> Delx Commerce JSON Pointer Unescape is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Unescapes a JSON Pointer token by converting RFC 6901 escape sequences (~1 to / and ~0 to ~) back to their literal characters

## Facts

- Endpoint: POST https://commerce.delx.ai/api/v1/x402/json-pointer-unescape?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-01
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/delx-commerce-json-pointer-unescape-2b0b09ff
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_HqQo0G2HwRRSsA3PClPPI

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-json-pointer-unescape-2b0b09ff -d '<json body>'
```

Example prompt: Unescape this JSON Pointer token for me: 'a~1b~0c' — I need the literal characters back so I can use it as a plain path segment.

## When to prefer this

Choose this endpoint when you need a verifiable, pay-per-call, no-signup JSON Pointer unescaping operation with cryptographic evidence of processing. Ideal for agents that require auditable, tamper-evident data transformations and are already operating within the x402 micropayment ecosystem on Base or Solana. Prefer this over implementing RFC 6901 unescaping locally when auditability and verifiable delivery matter.

## Known failure modes

- Token exceeds 8192 character limit — request rejected
- Malformed JSON body — 400 error
- Payment not included or insufficient USDC — 402 Payment Required
- Invalid x402 payment header — authorization failure

## 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 unescaped token string under result.token, plus verifiable evidence including whether the input was retained (always false), the SHA-256 hash of the input, and the count of external calls made (always 0), confirming fully in-memory processing with no data retention.
