Overview

Summarize a webpage. POST { url, instruction? }. Returns { url, finalUrl, summary (1-3 sentences), keyPoints (3-7 bullets), title, audience, estimatedReadingMinutes, meta:{ truncated } }. Sibling to /api/ai/extract — use extract when you need a typed payload conforming to your own schema; use summarize when you want a ready-made digest. Supports x402 upto billing: authorize the quoted max, pay only your actual usage.

Endpoint

Method	Endpoint	Price	Description
POST	/v1/marketplace/api/ai-summarize	$0.181125	Invoke Ai Summarize (Ai) 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://jarvisclaw.ai/v1/marketplace/api/ai-summarize \
  -H 'Content-Type: application/json' \
  -d '{}'

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