Call audit_ads_txt with exactly one of text or url. Diagnose common ads.txt and app-ads.txt seller-record problems before publishing or after an ad partner update: missing fields, malformed advertising-system domains, empty seller IDs, invalid DIRECT/RESELLER values, duplicate account/relationship tuples, and conflicting relationships for the same account. Each finding includes its source line.
Optionally pass expected:[{system:'google.com',sellerId:'pub-123'}] to check whether specific accounts are declared. Domains and relationship types are case-insensitive; seller IDs are case-sensitive. Recognizes the standard no-sellers placeholder and preserves variable declarations in a bounded sample.
This is a syntax and declaration checker, not full IAB conformance or proof of actual seller authorization. Does not verify sellers.json, certification ownership, DNS existence, app-store ownership, subdomain/partner referrals, extension fields or ad delivery.
URL mode checks only the exact host's /ads.txt or /app-ads.txt over public HTTPS/443 with text/plain; respects robots.txt and blocks private networks with pinned DNS. No redirects, compressed responses, delayed crawling or root-domain discovery.
Up to 256 KiB/5,000 lines (text input 100,000 characters), a 20-second network budget, 100 findings and 20 sample records/variables; reports truncation and total counts. No paid upstream API, browser or stored history.
Free: 100 tool calls/month. Pro: $1/month for 1,000 total tool calls, no overage charges or automatic paid upgrade. One tool call is one request regardless of file line count.
