## 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 dynamic-service-pricing-0d5b5623 -d '<json body>'
```

Example prompt: Can you propose a shadow price for my service using dynamic pricing rules, with a cap so the suggested price never exceeds my maximum threshold — without touching any live prices?

## When to prefer this

Choose this endpoint when you need to evaluate or simulate pricing for a service in a safe, non-destructive way — specifically when you want dynamic price suggestions bounded by a maximum cap and must not alter live pricing. Ideal for pre-launch testing, policy validation, or agent-to-agent commerce scenarios where pricing proposals must remain non-committal.

## Known failure modes

- Missing or malformed input payload returns a 400-level error
- Price cap set to zero or negative may result in validation failure
- Unsupported service identifier returns an error response
- Network or upstream pricing engine unavailability causes 5xx errors
- Payment not attached or x402 handshake failure blocks the request

## How this service works

Propose capped shadow prices without changing live prices

## Output

Returns a proposed (shadow) price computed by the dynamic pricing engine, capped at a specified ceiling, without modifying any live or published service prices. The response includes the suggested price value and likely metadata about the pricing rationale or cap application.
