  "description": "Success rate and median billed cost of AlterLab scrape jobs per anti-bot vendor class and tier over a trailing 30-day window. success_rate = successful jobs / all jobs in the cell. The vendor class is the anti-bot defence detected on the job (none_observed when no defence was detected); other groups defences outside the named vendor families. Tiers are the fetch rung that finished the job (1-4; post-hoc 3.5/4.5 count toward 3/4; pre-tier cache replays are excluded); tier 'all' sums the vendor class across tiers. median_cost is the exact median billed price of successful jobs (jobs.credits_used, microcents; 1,000,000 microcents = USD 1), not infrastructure cost. Only customer jobs are counted: internal, admin, test and first-party crawler accounts are excluded. Any cell with fewer than 100 jobs is omitted. The dataset carries no customer, domain, URL or job identifiers.",
