Your agent makes calls; your bill scales with calls, not headcount. Credits roll over 90 days. Cancel any time. All tools on every plan.
FoxAPIs is a unified API gateway for builders and AI agents. Instead of signing a separate contract, learning a separate schema, and juggling a separate key for every specialized data provider you need, you wire up FoxAPIs once and reach all of them through a single endpoint, a single key, and a single bill.
Behind that one key sits a growing roster of high-value sources that are normally a pain to integrate individually — research, regulatory, financial, and on-chain data including pubmed, biorxiv, clinicaltrials, fda, uspto, lens, bls, etherscan, and defillama. Each one is exposed as a clean, documented tool with a predictable credit cost, so you always know what a call will do and what it will draw down.
FoxAPIs ships first-class integrations for the tools your agents and workflows already live in. Drop it straight into ChatGPT and Claude Desktop over MCP, call it from Cursor while you build, or chain it into automation platforms like Make and n8n. The same credits power every surface — there is no separate "agent plan" and no separate REST plan. Wire it up once and the tools are available everywhere you work.
Most data providers charge per seat or lock you into per-source minimums and annual commitments. FoxAPIs is usage-based: you buy credits, every tool deducts a transparent amount per call, and your spend tracks the work your agents actually do. One key. One bill. No per-source contracts. Cheap calls cost a single credit; the heaviest enrichment tools cost up to 25, and every tool page lists its exact price so there are never surprises. Unused credits roll forward 90 days, plans switch with a click, and the free tier needs no card — enough to wire up an integration and exercise every tool before you commit a dollar. Pick the plan that matches your call volume below, then grab a key and start building.
Grab a free key, point your agent or workflow at FoxAPIs, and call every source through one credit-based endpoint. No card required to start, and the free tier is enough to test every tool once.
