KEY INTELLIGENCE FOR MODEL SALES
One API key,
and a faster answer to who owns it, what it can sell, and what is still missing
TestKey.ai is not just another connectivity test. It helps supplier teams, channel teams, and marketplaces decide whether a key is commercially complete enough for onboarding, procurement, or listing.
Public read-only, no login, no database write. Just an instant commercial health check.

PUBLIC CHECKERNo login required
Check an API key now
Enter an API key and Base URL to identify the provider, visible models, pricing coverage, and listing readiness.
Public read-only check only. This tool does not create supplier applications, inventory drafts, or pricing drafts, and it does not replace vendor-side expiry or quota verification.
You will get four practical answers: who owns the key, how many models are visible, how complete the pricing is, and whether it is ready for listing.
A useful key is not defined by a 200 response. It is defined by whether the key can become something sellable, purchasable, or listable.
COMMERCIAL SIGNALS
This is not just a ping test
We turn a technical response into a business decision. The real value is knowing whether a key is ready for the supply chain before you spend time on manual review.
STEP 01
Enter the API key and Base URL
Run a public read-only identification pass.
STEP 02
Return models and pricing coverage
See matched models and gaps in one view.
STEP 03
Flag blind spots and risk
Know whether expiry and quota still require vendor-side checks.
STEP 04
Get listing guidance
Decide whether the key belongs in inventory, procurement, or a marketplace.
Identify the provider first
Many keys look OpenAI-compatible on the surface. We identify the real provider and protocol before pricing or listing goes wrong.
See the actual model inventory
Pull the real visible models behind the key instead of stopping at a single successful request.
Focus on pricing coverage
A visible model is not always a sellable model. Pricing coverage decides whether it is ready for listing.
Recommend the next step
Ready to list, list after pricing, models only, or not ready yet. That decision is more useful than raw JSON.
WHO USES IT
and a faster answer to who owns it, what it can sell, and what is still missing
The homepage gives users an immediate checker, and the lower section expands into provider-specific SEO landing pages for long-tail traffic.
Model suppliers
Understand what a key can really sell before onboarding it into your catalog.
Agents and channels
Check the key first, then decide whether to distribute it and how to price it.
Marketplace operators
Move pre-listing review into a single screen and reduce manual comparison work.
Procurement and presales
Judge business completeness before a key reaches a customer-facing workflow.
PROVIDER GRID
Lay out the supply side at a glance
The homepage should establish market density first, then route people into dedicated checker pages and the model library.

FAQ
Common questions
The most common misunderstanding is that “responds successfully” and “ready to sell” are two very different things.
Does TestKey.ai store my API key?
No. The public checker only performs an instant read-only check. It does not push the key into supplier onboarding or inventory workflows.
Why do I see models but low pricing coverage?
The key is available, but some models are not matched to an official pricing source yet. That gap is exactly what you want to expose before listing.
Why can’t TestKey.ai show remaining expiry days?
Most vendors do not return key expiry from public model APIs, so vendor-side console verification is still required.
Who is this tool for?
It is built for suppliers, agents, API channels, procurement teams, and marketplaces that need to assess whether a key is commercially usable.
