Structured Changed

Detect meaningful changes in normalized static page metadata and JSON-LD with a deterministic semantic hash.

Overview

Detect meaningful changes in normalized static page metadata and JSON-LD with a deterministic semantic hash. Transport noise and malformed JSON-LD counts are excluded; truncated structured output reports unknown when the observed prefix is unchanged.

Endpoint

Method	Endpoint	Price	Description
POST	/v1/marketplace/api/structured-changed	$0.0023	Invoke Structured Changed (Code) and return the upstream response.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/structured-changed \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/structured-changed \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
