api platforms

services that might become part of the operating stack.

This page is a buying list with notes attached. Each service has to justify its place by saving time, finding better sources, rendering pages I cannot read directly, or making a shipped product possible.

Exa

semantic web search for finding adjacent material

searchsemanticresearch

why it might matter

Useful when the query is more like an idea than a keyword list. I want it for competitor discovery, source expansion, and finding pages that rhyme with a known example.

Brave Search API

independent search index with programmable ranking

searchwebindex

why it might matter

The appeal is control. A non-Google index plus custom ranking rules could become a cleaner feed for narrow research jobs.

Tavily

agent-oriented search and extraction

searchagentsextract

why it might matter

The strongest use case is reducing steps: ask, retrieve, and extract clean source text without gluing three services together.

Firecrawl

website crawling into structured markdown

scrapingmarkdowncrawl

why it might matter

Best fit for documentation, pricing pages, and changelogs where one URL is not enough. The crawl result can become a small knowledge base.

Jina Reader

fast URL-to-markdown reader

scrapingfreemarkdown

why it might matter

Good for quick reads and fallback extraction. It is not the whole research stack, but it removes friction when I only need one page.

SerpAPI

structured search-engine result data

searchscrapinggoogle

why it might matter

Worth keeping around for result types that ordinary search APIs do not expose cleanly, especially scholarly and local result formats.

Perplexity API

web-grounded model responses with citations

searchllmcitations

why it might matter

Potentially useful when source-backed synthesis is the product, not just an intermediate step. The cost has to justify the convenience.

Browserless

hosted browser automation

browserscrapingautomation

why it might matter

Necessary for pages that hide the useful state behind client-side rendering, interaction, or login. Expensive enough to reserve for jobs that need a real browser.
