Inputs

How to call it

# Needs an API key. The whole check is charged once, at the listed price.
curl -X POST https://api.strale.io/v1/solutions/competitor-read/execute \
  -H "Authorization: Bearer $STRALE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "inputs": {
      "url": "https://example.com"
    },
    "max_price_cents": 20
  }'

# No account. The first request answers 402 with the price in USDC;
# an x402 client pays it from your wallet and repeats the request.
curl -i -X POST https://api.strale.io/x402/v2/solutions/competitor-read \
  -H 'Content-Type: application/json' \

Limitations

• Trustpilot, Glassdoor, LinkedIn, Google Search, Google Patents, Reddit and the major social platforms (Facebook, Instagram, X) are not supported and return a policy error before the page is read. Repeating the same request does not return content.

  From step: Tech Stack Detection

• Database covers 1,000+ technologies — niche or custom-built tools may not be identified

  From step: Tech Stack Detection

  What to do instead: Check the raw HTTP headers in the response for custom X-Powered-By or Server values that indicate unlisted technology

• Detection based on HTTP headers, JavaScript libraries, and HTML signatures — technologies loaded conditionally or server-side only may not be detected

  From step: Tech Stack Detection

  What to do instead: Complement with dns-lookup and ssl-check results to infer infrastructure choices not visible in the HTML

• Pages with more than 16 MiB of HTML are refused with a caller_input error naming the input field. The call is not charged, and the page is not retried through another fetch or rendering route.

  From step: Tech Stack Detection

• Extracts meta tags from the initial HTML response — dynamically injected meta tags via JavaScript are not captured

  From step: Metadata Extraction

  What to do instead: Inspect the page in a browser for meta tags added by JavaScript.

• Pages with more than 16 MiB of HTML are refused with a caller_input error naming the input field. The call is not charged, and the page is not retried through another fetch or rendering route.
