AgentSearch is an open-source search API built for AI agents that want reliable web access without vendor lock-in or per-query billing. It bundles SearXNG under the hood — routing queries through 70+ search engines including Google, Bing, and DuckDuckGo — and returns deduplicated, ranked results based on cross-engine consensus rather than single-source rankings. One Docker command gets you a production-ready server with bearer token auth, rate limiting, and in-memory caching on port 3939. What makes AgentSearch especially useful is its 9-strategy content extraction chain: when a direct fetch fails, it cascades through readability parsing, the Wayback Machine, Google Cache, and other fallbacks until it gets clean text. Agents receive structured JSON designed for LLM consumption rather than raw HTML. There's also a "deep search" mode that expands queries into multiple variations and fuses result rankings using RRF (Reciprocal Rank Fusion). The project ships with a native MCP server, making it a drop-in replacement for Tavily or Serper in any Claude Desktop, Cursor, or Windsurf setup. For teams spending $200-500/month on search APIs, this is a compelling self-hosted alternative that keeps all data on-prem.

ds2api
Go middleware that routes any AI client to OpenAI, Claude, or Google APIs with rate rotation

ds2api is a lightweight Go middleware server that acts as a protocol translation layer between AI clients and multiple provider APIs. It accepts requests in any major client format and converts them to the target provider format — covering OpenAI, Anthropic Claude, Google Gemini, and others. Multi-account rotation is built in: you can pool API keys across accounts to spread load and reduce rate-limit exposure. The project is minimal by design — a single Go binary that runs locally or in a container. It's aimed at developers and teams who work with multiple AI providers and want a single endpoint that handles format conversion and key rotation transparently. No vendor lock-in, no cloud dependency. ds2api is gaining traction in the local LLM and API arbitrage communities who run self-hosted models alongside commercial APIs and need a clean routing layer. The multi-account rotation feature is particularly relevant for power users who maintain multiple accounts across providers to work around per-account rate limits — a controversial-but-common practice.
Reviewer scorecard
“Finally a proper self-hosted Tavily drop-in. The MCP integration means I can wire it into Claude Desktop in five minutes flat, and the 9-strategy extraction chain actually works when direct fetch fails. The Docker compose one-liner seals it — this is production-ready on day one.”
“Single-binary Go middleware with zero dependencies for multi-provider API routing is exactly what I've been hacking together manually. The key rotation is the killer feature for anyone running high-volume agent workloads against rate-limited APIs.”
“SearXNG-based meta-search has a frustrating failure mode: when Google or Bing return CAPTCHA challenges the whole result quality tanks. You'll need a good residential proxy setup to keep this reliable at scale. And most teams aren't spending enough on search APIs to justify the ops overhead.”
“Multi-account rotation specifically to evade rate limits sits in murky territory for most providers' terms of service. Using this in production could get accounts banned. The legality question matters before you build your infrastructure on this.”
“Search is becoming the connective tissue of every agentic workflow, and right now it's gated behind per-query billing that makes long-running agents expensive. Self-hosted search infrastructure like this will be table stakes for any serious AI ops team within 18 months.”
“Protocol translation layers are foundational infrastructure for the multi-model world we're heading into. Tools like ds2api are what allow developers to build provider-agnostic systems today, before providers offer official cross-compatibility.”
“For anyone building research agents or content pipelines, this is a game-changer. Reliable web access without watching the API bill is exactly what autonomous content workflows need. The structured JSON output means less prompt engineering just to parse results.”
“For most creators, this adds unnecessary infrastructure complexity. Unless you're burning through rate limits regularly, just use the official SDKs and switch providers manually when needed.”
