Agent Credit Router

One API key and one MCP endpoint for every agent web-data provider.

Summary

BriefingSelf-reported

A credit-aware, bring-your-own-keys gateway that routes AI agents' search, scrape and browser calls across Exa, Firecrawl, Tavily, Parallel, Browserbase and others, spending free credits first and failing over when credits run out. Demand is real: the LinkedIn origin post drew 193 reactions and 52 comments, and HN 'Treg (OpenRouter for Tools)' got 48 points.…

But at least six funded or launched competitors already exist (AgentKey 5,000+ users self-reported, YC-backed Agentmuxer). POS 66; recommended as a module of a broader agent-connection hub, not a standalone business.

DescriptionEstimate

One API key and one MCP endpoint for every agent web-data provider. Users paste their own provider keys (one account per provider). The router keeps a ledger of each provider's remaining credits and expiry dates (read via balance APIs or estimated from metered usage), normalizes search/extract/browse requests into one …

schema, routes each call by capability, quality benchmark and credits left (free first, then cheapest compatible), and fails over automatically on 429/402/quota errors. It also exposes a credits_status MCP tool so agents can plan before a call fails. Unlike reseller routers (AgentKey, Agentmuxer, ToolRoute, Monid, OpenRouter web plugins) it does not sell credits. Its incentive is to minimize the user's tool spend. Best packaged as a paid add-on inside a broader agent-connection hub, sharing its vault, endpoint and billing.

Target customer

Solo agent builder running a multi-agent fleet (Claude Code / Hermes / OpenClaw on cron), holding free or starter keys for 5+ search/scrape/browser providers, wants tool spend under ~$50/mo, and loses overnight runs to 429s and expired credits.

Pain

When my agents call several VC-subsidized search/scrape/browser providers, I want one endpoint that knows every key, balance and expiry date and picks the best provider with credits left, so I can run agents unattended at the lowest cost without runs breaking.

Why this score

Why it scored lower: Business viability HIGH: crowded and funded field (AgentKey, Agentmuxer YC, ToolRoute, ToolRouter, Monid, SearchRouter, OpenRouter plugins).

Moat

Weak standalone (copyable in weeks; open-source search-cli already reports credits). Defensibility comes from bundling with a broader agent-connection hub: one vault for OAuth apps and API keys, config stickiness of a single MCP URL, one subscription, plus public routing-quality benchmarks. Incentive is the opposite of reseller routers: save the user's credits.

LinkedIn post by Jaya Gupta (Oct 11 2026): 193 reactions, 52 comments in ~1 week (verified). HN 'Treg (OpenRouter for Tools)' Oct 6 2026: 48 points, 10 comments (verified via HN API). NousResearch hermes-agent issue #29771 (credential pools for Tavily/Exa) open since May 2026, raised to P2; users run local Tavily key-rotation patches; Exa returned 10x 429 on a 20-request burst.…

GitHub repos hand-route to Tavily/Exa free tiers (~1K/mo each) and keep Firecrawl as a paid fallback. Competitors: AgentKey claims 5,000+ users (self-reported); Agentmuxer launched on YC Aug 2026. Provider revenue context: Exa ~$10M annualized Sep 2025, ~11x YoY (Sacra); Trends.vc estimates Exa $9.5M, Jina $8.0M, Tavily $6.2M per year. Pricing anchors: Tavily free 1,000 credits/mo, PAYG $0.008/credit; OpenRouter Exa search $0.007/request.

Tech stack

Risks

Main risk

Business viability HIGH: crowded and funded field (AgentKey, Agentmuxer YC, ToolRoute, ToolRouter, Monid, SearchRouter, OpenRouter plugins).

All risks

Business viability HIGH: crowded and funded field (AgentKey, Agentmuxer YC, ToolRoute, ToolRouter, Monid, SearchRouter, OpenRouter plugins). Providers may restrict proxying or kill free tiers. Multi-account credit farming breaks provider terms (excluded from scope). Value: free-seekers have low willingness to pay. Feasibility: some balances are dashboard-only and 'compatible' providers are not drop-in equivalent.
