Questions people ask
Is TokenZero a drop-in alternative to TrueFoundry AI Gateway?
TrueFoundry AI Gateway is an enterprise gateway with routing, rate limits, guardrails and observability, part of an ML platform. TokenZero is a BYOK gateway: you keep your platform; point the model provider base URL at TokenZero where the gateway lets you, and every call comes back with a signed receipt. Free up to the monthly free tier, then a share of verified savings; no platform contract.
What does switching from TrueFoundry AI Gateway to TokenZero save?
It depends on your prompts; on the reference workload (100,000 calls of 2,000 input with a 1,500-token static prefix and 300 output on gpt-6.1-sol, table 2026-10-26) prefix caching alone cuts $700 to $415 a month, $285 saved and $242 net after the 15% fee; exact-cache hits and cascade routing add to that. The receipts show the real figure.
Can I keep TrueFoundry AI Gateway and add TokenZero?
Usually yes: chain them by pointing TrueFoundry AI Gateway's upstream at https://tokenzero.sh (or TokenZero's X-TokenZero-Upstream at TrueFoundry AI Gateway); the receipt still prices the request at list and records what the gateway did.
How is the 15% fee computed?
On verified savings only: list-price baseline minus provider-reported actual cost, per signed receipt. A cycle whose savings are below 3x the fee is billed $0; Pro Cap and Scale Cap add monthly ceilings. The first $500 of routed spend each month is free.
