How a job works
One running job per account. Accept .csv, .txt, or .tsv up to 64 MB and 1,000,000 unique addresses. Paste is still there for a short list. Spreadsheets (.xlsx) are rejected — export CSV first.
From the API you can POST JSON accounts for small lists, or multipart file for a large upload. Poll /api/v1/job/status for progress, credits charged, and top countries.
What you download
When the job finishes you get segments you can load into an ESP: Valid, Invalid, Errors, Risky, Remaining, Valid + country, plus Results.csv / Results.zip. Remaining and Errors can be sent back as the next job without pasting them into the tab.
What you pay
The job report splits 1-credit checks, 2-credit country checks, and free results. Unknown, error, and risky are never billed. Credits are pay as you go and do not expire. Country is optional for the whole job.
Throughput depends on the list and the network. The dashboard shows speed, outcome counts, and credits as the job runs — not a fake “records per second” promise.
