Different plans correspond to specific concurrency limits; please do not exceed these limits, as doing so may increase the error rate.
If you require higher concurrency, please contact us; we can provide customized services.
Quota verification is performed before each request is executed; if the balance is insufficient, the request will return error code 110301.
The crawler service API applies rate limiting or capacity control based on your plan and current service capacity.
When limits are triggered, the system may return error code 120401 or 120402.
If you encounter these errors, we recommend reducing concurrency or retrying later.
