APIs

Explore the APIs category for structured AI extraction, web data collection, and vision intelligence you can plug directly into agent workflows. Tools like LlamaParse, Hireability, Airparser, and Affinda turn messy resumes into clean structured data, while Firecrawl and Oxylabs Web Scraper API extract web content at scale for LLM-ready pipelines. You’ll also find APIs like Google Cloud Vision API and Amazon Rekognition API for image analysis, plus Jina AI Reader API for fast content extraction built for AI systems.

Ranking

Best AI Web Search and Answer APIs for Agents

For agent builders who need live web grounding, this comparison tests which APIs surface the right pages, current facts, usable page text, honest citations, and acceptable latency/cost when all tools are fed the same 52-query ground-truth set.

Jina logo
Tool

Jina

Rich web search results for agents, but this free-tier run was incomplete and not comparable.

You.com logo
Tool

You.com

Best-in-benchmark top-1 web retrieval for agent queries, with full-page text and published dates — but at a measured high all-in cost.

Vectorize.io
Tool

Vectorize.io

Managed RAG API with clean ingestion, OCR, and public pricing, but with caveats on refusals and freshness.

Vectara
Tool

Vectara

Vectara gives you a grounded-answer API with strong refusals, but tables, contradictions, scans, and pricing are the weak spots.

Exa logo
Tool

Exa

Best live-web search API here for agents that need ranked results, long page text, and cited answers.

OpenAI web search
Tool

OpenAI web search

A citation-honest control arm for live-web answering, but not a reliable retrieval layer for fresh content.

Valyu logo
Tool

Valyu

Returns usable web text for agents, but the citation layer is too error-prone to trust.

SerpAPI logo
Tool

SerpAPI

Fast, zero-error live web search for agents, with stable mid-pack retrieval and snippet outputs.

Linkup logo
Tool

Linkup

Standard mode is the usable tier: strong extraction, weak ranking; deep is slower, pricier, and weaker.

Fast, cheap raw web search for agents — strong on ambiguity, but too snippet-thin to replace a scrape.

Tavily logo
Tool

Tavily

A web search API that returns full-page text well, but usually buries the best result.

Unstructured
Tool

Unstructured

Good for text-first PDF-to-Markdown workflows, but not for faithful tables, charts, or images.

docTR
Tool

docTR

Fast OCR for PDFs when you need raw text, digits, and speed more than preserved Markdown structure.

Media
Tool

HrFlow

HrFlow is an API-first resume parser that covers core fields well, but needs cleanup for phones, casing, and certifications.

AI for Database
Tool

AI for Database

Plain-English live database querying with inline SQL, charts, follow-ups, and cost visibility.
