How this service works
Bulk http3 support: up to 20 domains in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /monitor/http3 endpoint (HTTP/3 and modern-transport support). Batch enrichment for agents that hold a list. $0.01 per batch.
Output
An ordered array of per-domain results matching the input list, each indicating whether the domain supports HTTP/3 and modern transport protocols, along with a per-item error field if detection failed, and a summary count of total failures across the batch.
Example use cases
Audit competitor HTTP/3 readiness
“Check HTTP/3 support for these 10 competitor domains all at once: apple.com, google.com, amazon.com, microsoft.com, meta.com, netflix.com, adobe.com, salesforce.com, shopify.com, and cloudflare.com — I want to see which ones have modern transport enabled.”
Pre-launch infrastructure verification
“Before we go live, can you verify that all our domains support HTTP/3? Check these: app.mycompany.com, api.mycompany.com, cdn.mycompany.com, www.mycompany.com, and static.mycompany.com in one shot.”
Client portfolio HTTP/3 compliance report
“I need to know which of my clients' websites support HTTP/3 — batch check these 15 domains for me: domain1.com, domain2.com, domain3.com, domain4.com, domain5.com, domain6.com, domain7.com, domain8.com, domain9.com, domain10.com, domain11.com, domain12.com, domain13.com, domain14.com, domain15.com.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/bulk/monitor/http3When to prefer
Use this endpoint when you have a list of 2–20 domains and need HTTP/3 support checked efficiently in parallel rather than making sequential single-domain calls. Ideal for batch audits, competitor analyses, or pre-launch infrastructure checks where throughput and ordered results matter. Prefer the single /monitor/http3 endpoint only when checking a single domain.
Side effects
- Domain unreachable or DNS resolution failure results in per-item error field set
- Invalid domain format causes per-item error
- More than 20 domains provided may be rejected or truncated
- Network timeout per domain included as per-item error
- All domains unreachable results in high failure count
