Extract clean, LLM-ready content from up to 5 URLs in one call. POST { urls[], depth? }. Returns the main text content of each page (JS-rendered, boilerplate stripped) plus a list of any URLs that failed. For feeding web pages to an agent without running your own headless browser.
/api/search/extractPAYMENT-SIGNATURE.The extract API is a pay-per-call search endpoint built for AI agents and autonomous software. Extract clean, LLM-ready content from up to 5 URLs in one call.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in extract data source for an agent tool-use loop, an MCP host, or a backend that needs search data on demand without onboarding to yet another vendor portal.

# 1. Probe the endpoint with no auth — receive 402 with PaymentRequirements
curl -sS -X POST 'https://2s.io/api/search/extract' \
-H 'Content-Type: application/json' \
-d '{"urls":["https://example.com"],"depth":"basic"}'
# 2. Sign the EIP-3009 transferWithAuthorization for the advertised price +
# payTo from the 402 envelope, then retry with PAYMENT-SIGNATURE:
curl -sS -X POST 'https://2s.io/api/search/extract' \
-H 'Content-Type: application/json' \
-H 'PAYMENT-SIGNATURE: <base64-json-payload>' \
-d '{"urls":["https://example.com"],"depth":"basic"}'
