## 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

## Yep.com

Yep is built on the same crawling infrastructure that powers Ahrefs, with an index that spans about 100 billion pages and refreshes roughly 8 billion of them every 24 hours. Rather than selling a general search box, it is positioned as a retrieval layer for AI: the API accepts a query along with filters such as include or exclude domains, categories, location, page type and language, then returns ranked pages and matching passages your model can read directly.

The service is aimed at developers building RAG pipelines, AI agents and research tools who want open-web context in one call instead of scraping and maintaining their own crawler. Results arrive structured, which reduces the post-processing needed before a prompt is constructed.

Pricing is deliberately simple and prepaid: $15 in free credit at signup with no card required, then $0.004 per request for a balanced result set of 1 to 50 results. You define spending limits, and there is no overage billing, so costs stay predictable. It is best understood as an independent search and retrieval API with the heritage of a former consumer search engine rather than a mass-market search destination.

**Pricing & Plans:** Free credit to start: $15 in credit at signup, no card required. Ongoing usage is prepaid and metered at $0.004 per request for a balanced result set of 1 to 50 results. You set spending limits and there is no overage billing.

- **Independent web index:** Submit a query and receive ranked pages, not just links, from an independent index so you are not dependent on a single commercial search provider.
- **Passage-level results:** Each result includes the passages that answer the query, so a language model can read relevant context without parsing entire pages.
- **One-call agent grounding:** A single endpoint call returns open-web context for your model, designed for RAG and agent grounding workflows.
- **Large, refreshed corpus:** Roughly 100 billion pages crawled since 2010 with around 8 billion refreshed every 24 hours, which keeps results reasonably current.
- **Predictable pricing:** Prepaid pricing at $0.004 per request with limits you define and no overage charges, plus $15 free credit at signup.

**Strengths:** Independent index with roughly 100 billion pages gives an alternative to mainstream search providers; Returns ranked pages and matching passages, cutting the work of extracting usable context; One-call agent grounding simplifies RAG and AI agent pipelines; Very low published rate of $0.004 per request and $15 free credit to test

**Limitations:** The consumer-facing search portal has been wound down, so the value is concentrated in the API rather than a general web search destination; A 403 Cloudflare challenge can appear for automated clients, so agents need proper API auth rather than scraping the homepage; Billing is prepaid per request rather than a flat free-forever plan for scale usage; Only one pricing tier is published publicly, limiting flexibility for very high or very low volume needs
