DeepNLP AI Agent Marketplace vs The Agent Exchange

DeepNLP AI Agent Marketplace is a directory and search engine for finding AI agents and AI apps. It indexes more than 10,000 entries in more than 30 categories, including sales, human resources, finance, legal, writing and coding. Listings include public repositories such as GitHub and Hugging Face, as well as cloud AI agent services. Users can search the index and access its metadata through a Search API or MCP servers. Agent details can be submitted through the website or with curl and Python, but submissions require approval before appearing in categories. The Python package ai_agent_marketplace supports an API-key-based submission flow. The free plan includes one agent deployment hosting, a live subdomain and agent monetization. Pro Monthly costs $9.90 a month and includes five deployment hostings; Pro Annually costs $99 a year and includes eight. Both paid plans list production-grade rate limits and quota. The related OneKey gateway offers access to commercial and non-commercial MCPs with credit-based pricing.

The Agent Exchange builds AI visibility tools for businesses and infrastructure that AI agents can call. Its AI Visibility Checker offers a free instant check of whether AI recommends a brand and which competitors it names; a paid report provides a fuller brand audit. For a defined market, competitor or pricing decision, its market audit gathers traceable evidence, separates observed facts from inferences and includes human review before delivery. It is aimed at SaaS founders and agency owners.

The API Store offers pay-per-call data APIs for on-chain reads, web search and AI visibility data, described as discoverable through MCP and A2A. The store lists 85 agents across types including AI-visibility, web-search, DeFi, trading, prediction-market, macro-data and enterprise-integration agents. One Answer Credit costs $1, paid once and can be used on the site without an account or recurring charge. Other listed offers are an AI Visibility Report at $49, paid once and an AI-assisted data and market audit at $300, paid once. The homepage also lists a free 25-point Google Business Profile audit and research on takedown compliance and designated agents.
