When an agent wants this
- Find competitors of a company from its homepage

- Find alternatives to a product or tool page

}Questions
Is there an Exa-style endpoint?
Yes: POST /v1/findSimilar takes url, numResults, excludeSourceDomain, domain and date filters and contents.
What if the page cannot be read?
The search is built from the URL's own words, so the call still answers.
How do I pay?
Each successful call costs the tool's price; failed calls are not charged. Then pay with card credits from $1 (the key goes in an Authorization header or as api_key= in the URL) or per call in USDC over x402 or MPP. No account is needed.
