Stork Quadrant

Becomes the API· 27/100

Replaceable as a UI, but kept alive as the API the agents call.

“Exa is a well-executed search API but it has no moat. The crawling and extraction layer is infrastructure any well-funded competitor can replicate, and the big players — Perplexity, Google, Bing — already offer API access to the same live web. LLMs with browsing tools eat the core use case directly. The only edge Exa has today is developer ergonomics and neural ranking quality, neither of which compounds.”

  • Summarize or extract structured content from a given URL
  • Generate search queries and synthesize results into a research brief
  • Answer questions using web-sourced information
  • Crawl and parse webpage content into clean text

How to defend

Pick a vertical where freshness and structured extraction are mission-critical — financial filings, legal dockets, biomedical literature — and own the data pipeline for that vertical with proprietary parsing and refresh rates nobody else matches. Stop competing on general web search and become the authoritative feed for one domain.

  • Add a usage-based or per-call tier; per-seat-only pricing dies when agents replace seats (+15).
  • Publish an OpenAPI spec at /openapi.json or /.well-known/openapi (+10).
  • Publish a public changelog and ship in the last 90 days — silence reads as abandonment (+10).
  • Ship an /llms.txt file pointing agents to your most important docs (+5, easy win).
