How this service works
USDC pay-per-call APIs for AI agents via the x402 protocol (v2, exact, Base mainnet). Send a request, receive HTTP 402 with payment requirements, pay with @x402/fetch or any x402 client, retry with the PAYMENT-SIGNATURE header.
Output

Example use cases
Summarize a news article from URL
“Grab the article text from https://techcrunch.com/2024/05/01/openai-news/ and give me a 3-sentence summary of what it says.”
Research content from a competitor page
“Extract all the readable body text from https://www.competitor.com/about so I can analyze what messaging they use.”
Feed webpage content into a Q&A
“Get the text content out of https://docs.example.com/faq so I can answer questions about it without having the user paste the whole page.”
Technical details
Endpoint
POSThttps://call402.com/api/text-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need clean, readable main-body text from a public webpage without dealing with HTML parsing yourself. It's ideal for feeding article content into summarization, Q&A, or analysis pipelines. Prefer it over raw HTML scrapers when you want Readability-processed prose rather than full DOM content. Best for news articles, blog posts, documentation pages, and other text-heavy public URLs. Avoid it for paywalled, login-required, or JavaScript-heavy single-page applications.
Side effects
- URL is not publicly accessible or requires authentication — extraction will fail or return empty content
- Page is JavaScript-rendered (SPA) with no server-side HTML — Readability may return little or no text
- URL points to a PDF, image, or non-HTML resource — not supported
- Malformed or invalid URL in request body — likely 4xx error
- Page blocks server-side crawlers via robots.txt or IP blocking — may return empty or partial content
- Payment not attached or invalid PAYMENT-SIGNATURE header — returns HTTP 402 with payment requirements
