Free product AI API routers & providers
The Free product category of the UPROUTER.ONLINE directory tracks 5 AI API routers and providers, each with normalized pricing, a free-tier value where one exists, a risk rating and a live status probe.
Across the category, 5 of them run a free tier worth $156.50 in free credits in total — the largest belong to LongCat, Pollinations, Agnes AI; 5 are Connect-ready (OpenAI- and Claude-compatible); 4 were up in the latest status check. These figures are recomputed from the live directory, so the counts shift as providers change their tiers and pricing.
Entries are ordered by free-credit value — a data sort, never sponsored — and every row links to a full entry with source URLs, a verification date and a change history. Inclusion is informational only; always verify current terms with the provider before you purchase.

What is an AI API router?
An AI API router is a service that exposes AI model APIs (often OpenAI- or Claude-compatible endpoints) so you can call many models — from different vendors or free and paid tiers — through one interface, with a single key and one billing surface.
How is the free-credit value calculated?
Free-credit values are normalized estimates in USD from public sources (signup bonuses, monthly quotas and usage allowances). Estimates are flagged on each entry; values we could not quantify are shown honestly as "Unknown" or "Not quantified" instead of invented numbers.
Is the ranking sponsored?
No. Every list on UPROUTER.ONLINE is ordered by data (free-credit value, price, risk rating or community score). There is no pay-to-rank — affiliate and referral links never influence data, scores or sorting.
How do I know a router is safe to use?
Each entry carries a risk rating (low / medium / high / unrated) with the reasoning behind it, a data-confidence score and live status. Risk is an evidence rating from community research — treat it as a starting point and always review the provider terms yourself.
