The whole sync is three small pieces of code. Pick a step to see it. 

let cursor;
do {
  const url = new URL("https://api.datahyena.com/v1/funding-events");
  url.searchParams.set("limit", "100");
  if (cursor) url.searchParams.set("cursor", cursor);

  const res = await fetch(url, {
    headers: { "X-API-Key": process.env.DATAHYENA_API_KEY },
  });
  const { data, pagination } = await res.json();
  await save(data);
  cursor = pagination.nextCursor;
} while (cursor);

The API, answered.

The essentials before your first call.

How do I authenticate?
Send your API key in the X-API-Key header. Create one in the dashboard. You start with 50 free credits and no card.
How does pagination work?
Every list endpoint uses a cursor. Read pagination.nextCursor from a response and send it back as cursor to get the next page. It keeps working while new records arrive.
How is usage counted?
One credit per record returned, shown in meta.creditsUsed on every response. Filters run before counting, so you only pay for records you receive.
Is there an OpenAPI spec?
Yes, at https://api.datahyena.com/v1/openapi.json. Generate a typed client from it, or import it into Postman or Insomnia.
Do you have SDKs?
The API is plain HTTPS and JSON, so any HTTP client works. For a typed client, generate one from the OpenAPI spec.
Can I get pushed updates instead of polling?
Yes. Webhooks send each new record to your server as it is confirmed, with the same fields as the API.
