It's a split decision.
Choose Exa for agent workflows that need web search, relevant page content, cited research or scheduled monitoring. Its APIs cover more of that workflow, with usage charges across search, content and agent features. Choose Jina AI for URL-to-text extraction, web search, embeddings and reranking, or to connect those APIs through its MCP server. Jina's pricing is organized around token packages and documents RPM limits; compare expected request volumes and commercial-use needs before choosing.

02Pricing at real usage
Exa's Free plan includes $10 in monthly credits and a $10 onboarding bonus. Pay as you go is usage-based, with up to 25 Search QPS; listed charges include Lite Search at $4 per 1,000 requests, Contents at $1 per 1,000 pages, and Agent usage at $0.10 per ACU plus $0.005 per search. Higher Agent effort levels cost more per request. The custom option lists a $12,000 annual commitment in API credits for its enterprise zero-data-retention option.
Jina AI's Toy Experiment tier includes 10 million tokens for non-commercial use only. Prototype Development lists a $50 top-up for 1 billion tokens at $0.050 per million; Production Deployment lists $500 for 11 billion tokens at $0.045 per million. Optional auto-recharge is available, but its price isn't published. Neither pricing model is a monthly subscription; estimate costs against your request mix and limits.
03API, SDKs and integration
Exa exposes Search, Contents, Agent and Monitors APIs. Search provides results across categories including web, news, companies, research, people and financials; Contents returns webpage text and relevance-selected highlights. Agent supports research runs with structured outputs and citations, while Monitors can send scheduled search updates through webhooks. Exa also lists website-crawling tools and an Exa Library.
Jina AI's Reader API fetches URL content through r.jina.ai; its Search API uses s.jina.ai. The homepage also lists embeddings, a reranker and an MCP server at mcp.jina.ai, which lets LLMs call Jina APIs. Reader supports controls such as output format, CSS selectors, token budget and browser engine. Both homepages link to documentation, but name no supported SDK languages or CLI. Check the docs for client-library coverage and confirm that response formats fit your application.
04Open source, self-hosting and lock-in
Neither vendor's homepage states an open-source licence or self-hosting option. The described products are APIs and web tools: Exa exposes search, content, agent and monitoring services, while Jina identifies hosted endpoints for Reader and Search. Plan for a dependency on vendor-managed services unless the vendors confirm another deployment option.
The vendors don't describe data-export or migration procedures on their homepages. Before committing, ask what request logs, saved results, monitor configurations and account data you can export, and in what format. Keep vendor-specific request parameters and response parsing behind an internal adapter. That makes it easier to switch search or extraction providers, though replacing features such as Exa's cited Agent research or Jina's retrieval components may require application changes.
Questions people ask
Is Exa or Jina AI cheaper?
It depends on the workload. Exa lists request, page, ACU and enrichment charges; Jina AI lists token packages, including $50 for 1 billion tokens on Prototype Development. Compare the relevant units against your expected mix, and account for Jina's non-commercial free tier restriction.
Can I use Jina AI's free tier commercially?
The Toy Experiment tier is for non-commercial use only and lists a CC-BY-NC condition. Jina AI's paid Prototype Development and Production Deployment packages are listed separately. Review the applicable package terms before using the free allowance in a commercial product.
Does Exa or Jina AI provide an SDK or CLI?
Their homepages describe APIs and link to documentation, but name no supported SDK languages or CLI. Jina also offers an MCP server for calling its APIs from an LLM. Check each vendor's current docs for client libraries and command-line tooling before selecting an integration path.
Can I self-host Exa or Jina AI?
Neither homepage states a self-hosting option. Both describe API-based products, including Jina's r.jina.ai and s.jina.ai endpoints. If deployment control is a requirement, ask the vendor about hosting options, data handling and export before building against provider-specific features.
