# Delx Commerce ROT13 Encoder

> Delx Commerce ROT13 Encoder 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).

Encodes or decodes text using the ROT13 Caesar cipher substitution algorithm, paid per-call via USDC on Base or Solana.

## Facts

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-rot13-encoder-d465d3f7 -d '<json body>'
```

Example prompt: Can you ROT13-encode this text for me: 'Agent workflow'?

## When to prefer this

Choose this endpoint when you need a verifiable, pay-per-call ROT13 transformation without signup friction, especially in agent workflows that already use the x402 micropayment protocol on Base or Solana. Ideal for lightweight, one-off cipher operations where cost predictability ($0.001 USDC per call) matters. Not suitable for heavy-duty encryption or security-sensitive obfuscation needs.

## Known failure modes

- Input text exceeds 100,000 character limit — request rejected
- Payment not completed or insufficient USDC balance — 402 response returned
- Malformed request body or missing 'text' field — 400 error
- Network timeout or service unavailability — 5xx error

## 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 ROT13-transformed string in the 'result' field, the character length of the result in 'length', and a schema identifier 'delx/rot13/v1' for versioning. For example, input 'Agent workflow' yields 'Ntrag jbexsybj'.
