How this service works
Bulk is email hosted by yahoo mail: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.
Output
Returns an ordered array of results matching the input domain list. Each item contains a boolean indicating whether that domain's email is hosted by Yahoo Mail, plus a per-item error field if the lookup failed. A top-level failure count summarizes how many items encountered errors.
Example use cases
CRM email provider enrichment
“I have a list of 18 company domains from our CRM — can you run them all through at once and tell me which ones are using Yahoo Mail for their email hosting?”
Sales prospecting filtering
“We're targeting SMBs that use Yahoo Mail. Can you batch-check these 20 domains from our prospect list and flag which ones are on Yahoo Mail so we can prioritize outreach?”
IT audit of supplier domains
“I need to audit our supplier email infrastructure — can you check all 15 supplier domains at once and identify which ones are still hosted on Yahoo Mail?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/bulk/email/hosted-by/yahoo-mail?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check Yahoo Mail hosting for multiple domains (up to 20) in one call rather than making 20 individual requests. Prefer this over the single endpoint when processing a list from a CRM, prospect database, or audit export. At $0.10 per batch call, it is significantly more cost-efficient than calling the single endpoint 20 times.
Side effects
- Invalid or malformed domain name causes per-item error with error field populated
- More than 20 domains submitted exceeds batch limit
- DNS lookup failure for a domain results in per-item error rather than whole-batch failure
- Network timeout from Cloudflare DoH resolver causes per-item error
- Payment not received or x402 auth failure blocks the entire batch call
