Vercel AI Gateway
zero markup stated plainly, including on byok
the most explicit no-markup commitment in the category, with the compliance controls you would need at scale metered on top.
vercel's pricing page states it directly: 'ai gateway charges no markup and no platform fee on tokens', and the docs extend that to byok. a million input tokens of claude sonnet 4.5 costs anthropic's list rate, deducted from a prepaid credit balance, with nothing added. the gateway works from a free hobby account, which makes it the cheapest serious starting point here alongside cloudflare.
the routing story is solid — one key across hundreds of models, automatic retry and failover to other providers, load balancing, and compatibility with openai chat completions, openai responses and anthropic messages formats, so most existing code points at it unchanged. embeddings, image and video generation ride the same credit balance.
