Free-offer ranking

Each row describes the provider’s recorded free offer, which may cover a different product from the category shown here. The table keeps published units separate. “Not confirmed” means we lack evidence for that detail; it does not mean the provider requires a card.

Why these providers appear in this order

We score each provider’s recorded free offer: up to 40 points for recurring or durable access, 20 for a confirmed no-card signup, 15 for a stated allowance, 15 for distinct evidence links, and 10 for documented terms. Missing details earn no points. Ties favor longer-lasting access, then more detailed records, then provider name. The score does not measure product quality or whether the free offer covers this category. Read the full method before treating it as a recommendation.

Which providers are included?

We include active directory records tagged for AI agent platforms. A tag describes a provider’s capability; its recorded free offer may cover only part of that provider’s catalog. Check the model or endpoint in the provider’s terms before building on the allowance.
