## Calling rules

Store API_KEY in a trusted environment. /api/* accepts only browser sessions; external clients use /openapi/v1/* only. HTTP 202 means a task was accepted, not completed. Save data.id, wait at least data.pollAfterMs (6000ms), then query /openapi/v1/jobs/{id}. Read data.result only on succeeded; failed/canceled has data.error and refunds the credit reservation. Use an Idempotency-Key for retries of the same submission. Honor Retry-After on HTTP 429. Task lookup/listing is scoped to the authenticated account. Website diagnostics do not guarantee search rankings or AI citations.
