UU API AI Relay Review
Review UU API website uptime, official GPT and Claude pricing, API verification evidence, current offers, and clearly labeled risk notes.
API verification
AI Relay Check records model-level requests for UU API and keeps failed samples. A successful request proves only that specific model and route at that time.
Pricing and billing
Official input and output rates are displayed separately. Published prices do not become verified billing costs until token usage and account balance changes are reconciled.
Decision boundary
API availability does not by itself prove model identity, long-term reliability, refund support, or balance safety. Start with a small test balance.

A configured model without a sample is not verified. Results combine recorded requests for this model across test keys; the exact upstream group is not consistently recorded. P50 uses successful end-to-end responses only.

What the evidence means
Separate paid GPT and Claude routes are monitored, with broad model coverage and route-level published pricing.
Deep model-identity checks and request-level theoretical billing reconciliation are not complete for every route.
Users who need both Claude Code and Codex and can validate their main models with a small balance first.
Official-model controls, provider-published input/output/cache rates and multiplier for this route, long-term price-change tracking and peak-hour load tests.
Who, how and commercial disclosure
Website probes, provider-published prices and paid model calls are stored as separate evidence types. Failed calls remain in the sample.
API request costs are paid from AI Relay Check test accounts. Account credit can include our recharge and provider promotional credit; those sources are not yet separated in every record.
This provider has a dedicated registration offer or partner entry. AI Relay Check may receive referral benefits; commercial relationships do not change samples or ranking weights.
