What CredNull Is
CredNull is an independent directory and developer intelligence platform created to organize, verify, and track free AI credits, API allowances, free trials, and developer grants across frontier labs, open-weights hosters, and inference providers.
Why CredNull Exists
Prototyping and deploying modern AI applications requires evaluating multiple model providers, context windows, and latency profiles. However, developer offers are scattered across promotional tweets, outdated blog posts, and deceptive affiliate lists that fail to disclose mandatory payment card requirements or hidden expirations. CredNull exists to eliminate that friction with structured, dependable data.
What We Track
For every provider listed in our directory, we document normalized attributes:
- Credit Amount & Currency: Exact nominal value (e.g. $5, $25, €100) or token grant.
- Credit Type: One-time signup grant, trial window, rolling daily tier, or monthly free allowance.
- Verification Requirements: Explicit identification of payment card, SMS phone verification, or work email demands.
- Model Support: Precise taxonomy linking providers to supported frontier and open-weights models.
- Access Interfaces: Full separation between raw REST/gRPC API access versus interactive web chat interfaces.
Our Approach to Accuracy
We believe that "Verified" should mean tested. Our editorial team reviews official pricing documentation, signup flows, and terms before an offer receives a verified badge. All status changes are recorded in an append-only verification history visible on each provider's detail page.
Strict Separation of Sponsorship
Paid promotional placement is strictly labeled as "Sponsored". Sponsorship status NEVER influences an offer's verification badge, requirement flags, or placement within filtered query results. Verification cannot be bought.
What CredNull Does Not Guarantee
While we continuously audit the directory, cloud providers and model platforms reserve unilateral rights to modify their pricing, credit allocations, and rate limits at any time. We provide verified intelligence on an as-available basis and encourage checking each provider's official documentation before committing production architectures.
Who CredNull Is For
CredNull is built for software engineers, indie founders, student builders, researchers, and technical architects who need transparent, verified data to experiment with artificial intelligence without premature billing surprises.
Reporting Issues & Community Oversight
When an offer changes or expires, developers can submit a community issue report directly through any provider page. Reports enter an immediate editorial queue for re-verification.
