Pay-per-call web crawling agent that converts a URL into cleaned, structured text output.
What it does
This x402-enabled endpoint, hosted on Questflow's developer API, wraps a Jina-based web crawling agent behind a pay-per-request paywall using the x402 protocol on Base Sepolia. You send a POST request with a URL (as a string in the `input` field), and the agent crawls the target website and returns an improved, processed version of the page content as a text response.
Payment is handled via the x402 protocol using USDC on the Base Sepolia testnet. The maximum amount required per request is 100,000 units of the USDC token (contract 0x036CbD53842c5426634e7929541eC2318f3dCF7e), and the maximum timeout for a response is 1,200 seconds (20 minutes). The endpoint accepts `application/json` and returns a JSON object with a `response` string field.
Documentation is minimal — there is no OpenAPI spec, no dedicated docs page, and the crawl of the host domain reveals only Questflow's main marketing site for their AI Clone product. The agent's exact crawling behavior, output formatting, rate limits, and content-length constraints are not documented. Use with caution on a testnet environment.
Capabilities
Use cases
- —Crawling a webpage and extracting cleaned text for downstream LLM processing
- —Agents that need to read arbitrary web pages behind an x402 paywall
- —Converting HTML pages into structured or simplified text output
Fit
Best for
- —AI agents needing on-demand web page reading via x402 micropayments
- —Prototyping pay-per-call web scraping workflows on Base Sepolia testnet
- —Extracting readable content from URLs without managing a scraper
Not for
- —Production workloads requiring mainnet payment rails (this uses Base Sepolia testnet)
- —Bulk or high-throughput crawling (20-minute timeout, no documented rate limits)
- —Scenarios requiring detailed crawl configuration or JavaScript rendering guarantees
Quick start
curl -X POST https://api-dev.intra-tls2.dctx.link/x402/agent/qrn:agent:684abbca938f9dfa5feb0597 \
-H "Content-Type: application/json" \
-H "X-PAYMENT: <x402_payment_header>" \
-d '{"input": "https://example.com"}'Example
Request
{
"input": "https://example.com"
}Response
{
"response": "# Example Domain\n\nThis domain is for use in illustrative examples in documents..."
}Endpoint
Quality
No OpenAPI spec, no dedicated documentation, no usage examples from the provider. The only schema information comes from the x402 challenge's outputSchema. The endpoint is on a testnet, and the host site is primarily marketing for an unrelated AI Clone product. Significant inference was required for most fields.
Warnings
- —Testnet only: uses Base Sepolia USDC, not production mainnet
- —No OpenAPI or formal API documentation available
- —No docs, pricing, or README pages found on the host
- —Agent behavior, output format, and limitations are undocumented
- —The host domain's main content is about Questflow's AI Clone product, not this crawling agent
