## Octen

Octen provides the retrieval layer that AI products need to ground their answers in current, real-world information. Its core Web Search API returns ranked results with highlights and optional full page content, while a Broad Search endpoint automatically decomposes a single query into parallel sub-queries for faster coverage. Supporting products cover image and video search, news, business and place lookups, and an Extract API that turns any URL into clean Markdown with page classification.\n\nBeyond search, Octen ships embedding models that it positions at the top of public retrieval leaderboards, with a text embedding family and a multimodal vision-language embedding family that maps text, images, video, and visual documents into one shared vector space. Higher-level applications such as Answer, Search Agent, Deep Research, and Grounded Generation are billed per outcome and build on the same underlying APIs, so teams can start with raw search calls and graduate to packaged workflows.\n\nThe platform emphasizes operational characteristics that matter in production: it advertises flat latency at high concurrency, indexing of newly published content within minutes, and enterprise-grade reliability. Developers connect through REST APIs, SDKs, an MCP server, a CLI, and Claude Code skills, and new accounts receive a small free balance for testing.

**Pricing & Plans:** Pay-as-you-go credits plus optional plans. New accounts get $5 in free balance. A Search Plan starts at $20/month for unlimited web search, and QPS plans reserve guaranteed throughput from around $2,099/month up to custom enterprise tiers.

- **Low-latency web search API:** Returns ranked, LLM-ready results with highlights and optional full content, designed to hold steady latency even under very high query concurrency.
- **Broad Search query decomposition:** Automatically splits one complex question into parallel sub-queries and merges the results, giving agents broader coverage from a single call.
- **Text and multimodal embeddings:** Dedicated embedding families for text and for vision-language retrieval, letting teams embed pages, images, video, and documents into a shared vector space.
- **URL extraction with page classification:** Turns any URL into clean Markdown with intent-focused highlights and a classified page type, so downstream models receive structured, noise-free input.
- **Agent and MCP integration:** One API key works across REST, SDKs, an MCP server, a CLI, and agent skills, making it easy to wire search and extraction tools into popular AI coding and chat clients.

**Strengths:** Broad product surface covering search, extraction, embeddings, and packaged agent workflows under one key; Explicit focus on latency and throughput at high concurrency, with enterprise and QPS plans for guaranteed capacity; Multiple integration paths (REST, SDK, MCP, CLI, agent skills) suit both quick prototypes and production agent stacks

**Limitations:** Advanced and high-throughput tiers are priced for teams with real budget, not hobby projects; Some capabilities such as video search are marked early access, so availability may vary; Usage is credit-based across many endpoints, which takes care to model costs accurately

## 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
