How this service works
Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.
Output
A short text summary (between 10 and 250 words, defaulting to 60) extracted from the target product page, capturing the page's key content without requiring the caller to parse raw HTML.
Example use cases
Quick product research for price comparison
“Grab me a short summary of this product page — https://store.example.com/headphones/sony-wh1000xm5 — no more than 60 words, just the key details.”
Automated catalog enrichment pipeline
“For each of these supplier URLs, get me a brief extract of what the product is — start with https://supplier.example.com/items/42 and keep it under 100 words.”
Competitor product monitoring
“What does this competitor's product page say? https://competitor.example.com/products/smartwatch-v2 — give me a brief in 50 words or less.”

Endpoint
POSThttps://chain.tollkit.dev/web/brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-account-required product page summary and want to pay only for what you use via x402 crypto micropayments. Ideal for ad-hoc agents, one-off lookups, or pipelines that can't justify API key management overhead. If you need full HTML or structured product schema (price, SKU, reviews), a more comprehensive scraping service may be more appropriate.
Side effects
- Invalid or non-HTTPS URL returns a validation error
- Page behind login/paywall cannot be scraped and returns an access error
- max_words out of range (below 10 or above 250) returns a schema validation error
- Payment failure or insufficient USDC balance causes an x402 payment rejection
- Target page is unavailable or times out, returning a connectivity error
