75 Exa-first platforms where Keenable is not yet listed — 9 are ready for direct outreach now

Asked (summary):

Find all popular OpenRouter-style alternatives where Keenable should be added as a search tool — the ones that usually offer Exa first.

A broad live-web screen surfaced 75 popular or meaningfully adopted public distribution candidates — gateways, tool routers, MCP registries, marketplaces, agent frameworks and coding agents — where Exa is already offered and Keenable is not shown as present. The ecosystem has no fixed official universe, so this is a best-effort census, not an exhaustive denominator: sweeps examined up to 3,462 unique web results, and the 75 rows rest on 45 independent source hosts, with no single page supporting more than 12% of rows. “Exa first” is a discovery heuristic — Exa may be native, featured, listed, or reachable via MCP; each row states which.

The outreach queue: adoption signal by tier

Each dot is one platform. Horizontal position is research-mention count across the screen's source sweep (a proxy for how often the platform surfaces in the Exa-adjacent ecosystem). Rows are action tiers derived transparently from the supplied fields: Priority 1 = adoption evidence and a stated integration path; Priority 2 = adoption evidence or a well-mentioned integration path; Priority 3 = a listing or path exists; Watchlist = weaker proof. OpenRouter is shown as the reference, not an alternative. Colour is channel type. Hover or tap a dot for its exact Exa positioning.

Composio alone claims 1,500+ toolkits and 300M+ tool calls a month, and already ships Exa as an 18-tool toolkit through a single MCP endpoint — the single highest-leverage Priority 1 target. composio.dev

Self-serve registries move fastest: the Official MCP Registry holds 40,475 servers and lists Exa as ai.exa/exa, and Smithery's 7,000+-server directory accepts publication by anyone. stealwhatworks.com

The "OpenRouter for tools" niche is forming now — Monid, ToolRouter and AIsa each use that framing almost verbatim and each already lists Exa as a per-call search provider. monid.ai

OpenRouter itself — the benchmark — has made Exa its main live-web search engine across 400+ hosted models, with Parallel, Perplexity and Firecrawl as the neighbouring options Keenable would sit beside. johnsonshi.substack.com

All 75 candidates

Platform	Tier	Exa positioning	Why it matters / path in	Mentions	Source

Best-effort live-web census, 75 rows (one per normalized platform), screened from up to 3,462 unique web results across queries for AI gateways, tool routers, MCP registries, marketplaces and agent frameworks; 45 independent source hosts, largest single URL supports 12% of rows. “Mentions” counts appearances of the platform across the research sweep's sources, not market share. Tiers are derived from the supplied popularity-evidence and integration-path fields, not invented scores. Long evidence text is truncated in the table; full text appears in chart tooltips. Data gathered at screening time; no numbers were added beyond the rows.
