Send it one request.
The same endpoint, key and request shape
as every other model in the catalogue.
The example below is complete apart from the key. The endpoint speaks the OpenAI chat-completions shape, so a client that already sends a model name, a message list and a bearer token needs no wrapper around it: point the base URL at https://api.heartflowai.net/v1, paste a key in place of the placeholder, and name this model with the identifier in the table above.
Streaming, tool calling and the error codes behave the same here as they do for the rest of the catalogue, so a harness you have already wired up keeps working when you change that one string.
curl https://api.heartflowai.net/v1/chat/completions \
-H "Authorization: Bearer hfai_live_…" \
-H "Content-Type: application/json" \
-d '{"model":"neira-h4","messages":[{"role":"user","content":"Hello HFAI"}]}'
Paste a key where the placeholder is. The request shape, the streaming rules and the error codes are documented in the API reference.

Every figure above comes from the 11 rows the live catalogue returned when the page was built, and is recomputed on every check, so it cannot quietly stop being true. The statement about a model card, and the searches it reports, are the only facts here read from outside that catalogue, and both are dated above. No speed, quality or benchmark figure is claimed on this page.
The rest of the catalogue.
This model shares one endpoint, one balance and one API key with every other model on offer, so moving between them costs a single string.
