Is there a free tier?

Yes. Every new key starts with $0.05 of free credit, issued instantly with no credit card. One trial key per network per 24 hours.

Are there subscriptions, seats or minimums?

No. Vella Quant is prepaid credit only. You top up what you want (card top-ups start at $5), spend it at the metered rates, and nothing recurs. There are no per-seat charges and no monthly minimum.

Use the Add credit form on the pricing page, or POST to /v1/checkout with your api_key and amount_usd ($5 minimum) to create a card checkout session. Credit lands on the same key — keys are never rotated on top-up.

What $5 buys you

Concrete, at the rates above — so you can size a budget before writing any code.

12.5M chat tokens — roughly 9–10 million words of generated output.
250M embedding tokens — enough to index a very large document corpus many times over.
5,000 hosted search queries — a full RAG workload, retrieval included.
100 market briefings — a daily briefing for three months.

Reranking and document upserts are billed at the embedding rate, on the tokens they actually embed — there is no separate per-call fee.

Free credit, no card

Add credit

Paste the key you were issued, pick an amount, pay by card. Credit lands on the same key within a minute of payment — nothing rotates. $5 minimum.
