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

Every new key starts with $0.05 of credit, issued instantly by POST /v1/trial. That's ~125,000 chat tokens — plenty to evaluate the API properly. One trial key per network per 24 hours.
