## Exa

Exa started from the idea that search engines built for humans are a poor fit for AI systems that need precise, token-efficient context. Its core product is a search API with a large independent index, where queries can be semantic, keyword-based or configured for latency versus depth, and results come back with clean text, highlights and grounded citations rather than noisy page markup.

On top of search, Exa offers a contents endpoint for extracting page content, an agent endpoint and websets for finding sets of entities that match a description, along with monitors and integrations such as an MCP server. Search runs in tiers (roughly fast, balanced and deep) so developers can trade latency against research quality, and the same API supports verticals like code, finance, companies, people and news.

Exa markets itself to teams building AI assistants, coding agents, GTM and sales tooling, recruiting and finance research, and reports very large indexed document volumes and heavy token savings from its highlight-based content extraction. The company emphasises enterprise readiness with SOC 2 Type II, GDPR, CCPA and HIPAA-aligned controls and zero data retention options.

**Pricing & Plans:** Freemium: free API usage to start plus usage-based pricing, with custom enterprise plans available. Confirm current rates on the pricing page.

- **Semantic and keyword search API:** Run natural-language or keyword queries against a large independent web index with filters for domain, date and category.
- **Token-efficient contents:** Return cleaned page text and AI-extracted highlights so agents receive the most relevant excerpts instead of entire pages.
- **Agent and deep research endpoints:** Choose fast, balanced or deep search modes so an assistant can answer instantly or run longer grounded research.
- **Structured enrichment:** Extract structured outputs such as company details, people and other entities for list building and data pipelines.
- **Crawling and integrations:** Crawl URLs, track changes with monitors, and connect Exa to agents and IDEs through an MCP server and SDKs.

**Strengths:** Purpose-built for AI agents, not retrofitted from consumer search; Token-efficient highlights reduce context cost meaningfully for LLM applications; Structured enrichment plus search in one platform covers many pipelines; Strong compliance posture including SOC 2 Type II and zero data retention options

**Limitations:** Pricing is usage-based and requires monitoring to control spend at scale; Requires developer effort since it is primarily an API rather than a point-and-click app; Access to the deepest research modes costs more than fast lookups

## Serpex

Serpex provides two core endpoints behind a single API key: a Search endpoint that returns live web results as structured JSON, and an Extract endpoint that converts any URL into clean, readable markdown for AI ingestion. A standard search consumes one credit, and pulling page content along with results lets teams go from discovery to ingestion without juggling a second scraping vendor.

The service is positioned around affordability and throughput. Its published tiers scale from roughly $0.80 per 1,000 requests on small top-ups down to around $0.50 per 1,000 on the $500 tier, with custom pricing for very high volume. Serpex advertises automatic fallback across multiple underlying search sources, so if one source returns nothing the request fails over to another, along with retries and per-source health monitoring.

For developers, there are SDKs and integrations for Python, JavaScript, MCP and LangChain, plus a REST API. New accounts receive free trial credits without a card, and credits are described as non-expiring with a short money-back window on purchases.

**Pricing & Plans:** Pay-as-you-go credit model with a free trial (200 free credits, no card). Published tiers: Starter ~$0.80 per 1,000 requests ($5 top-up), Standard ~$0.65 per 1,000 ($50 top-up) and Scale ~$0.50 per 1,000 ($500 top-up); enterprise volume from ~$0.20 per 1,000. Credits are non-expiring and only successful requests are billed.

- **Search API returning structured JSON:** Send a query and receive live web results as clean, structured JSON that is ready for parsing, ranking or feeding into a model.
- **Built-in content extraction:** Convert any URL into clean, readable markdown in the same API key, removing boilerplate so retrieved text is directly usable for RAG and summarization.
- **Automatic source fallback:** Requests are routed across multiple underlying search sources with health monitoring and automatic retries, so a single empty source does not break your pipeline.
- **Developer SDKs and integrations:** Official libraries and snippets for Python, JavaScript, MCP and LangChain make it a few lines of code to add live search to an agent or app.
- **Pay-as-you-go credits:** Only successful requests consume credits, credits do not expire, and volume discounts scale from small top-ups up to high-throughput plans.

**Strengths:** Search and extraction in one API key, reducing vendor sprawl; Competitive pay-as-you-go pricing with volume discounts; Credits never expire and failed requests are not billed; Automatic fallback and retries reduce pipeline fragility

**Limitations:** No ability to pin a specific search engine source; engine selection is handled automatically; Free tier is a credit-based trial rather than an unlimited free plan
