# Relaystation Mustache Template Renderer

> Relaystation Mustache Template Renderer is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Renders a logic-less Mustache-subset template safely against a provided data context, with no eval and injection protection.

## 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 relaystation-mustache-template-renderer-e1bb3ce0 -d '<json body>'
```

Example prompt: Take this Mustache template — 'Hello, {{name}}! Your order #{{order_id}} for {{product}} has shipped.' — and render it with the data: name='Alice', order_id='98231', product='Wireless Headphones'.

## When to prefer this

Choose this endpoint when you need injection-safe, logic-less Mustache template rendering without running any server-side code or eval. Ideal for AI agents generating personalized messages, notifications, or documents from structured data where safety and predictability matter. Prefer over custom templating when you need a hosted, pay-per-use solution with no infrastructure overhead.

## Known failure modes

- Malformed template syntax causes a parse error and non-200 response
- Missing required context variables result in empty substitution or error
- Payload size exceeds limits billed at $0.0002/MB causing unexpected cost
- Invalid or malformed JSON in the data context object
- x402 payment not fulfilled results in 402 Payment Required response

## How this service works

$0.0002/MB. Render a logic-less mustache-subset template — no eval, injection-safe. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

Returns the fully rendered string output with all Mustache placeholders substituted with the provided context values. No code is evaluated; the output is a safe, plain-text or structured string with all {{variable}} tokens replaced.
