Weekly Reliability Report: Wellknown AI Agent Index Status

The index this week

As of 2026-11-01, the Wellknown index contains 80,527 records in total. Out of these, 39,544 are network-checkable, meaning they have endpoints that can be tested. Among the network-checkable records, 25,087 are live, indicating their latest check succeeded within the last 24 hours. There are 304 records recently observed, which means they had a successful check within 7 days but the latest check either failed or is older than 24 hours. The unavailable records number 9,146, representing those with two or more consecutive failures and no success in 7 days. The unknown category, which includes records with nothing to check or never checked, stands at 45,990. Over the last 7 days, a total of 3,559,116 observations have been made across the index.

Checks and latency

During the reporting window, 34,373 records were checked a total of 591,192 times. Of these checks, 575,409 were successful, resulting in a high success rate of 97%. Currently, 9,146 records are unavailable, and 8,909 records went unavailable during this period. Latency measurements show a median (p50) response time of 135 milliseconds, meaning half of the successful checks responded within this time. The 90th percentile (p90) latency is 553 milliseconds, indicating that 90% of responses were faster than this. The fastest recorded response was 2 milliseconds. For a caller, this means most live endpoints respond quickly, with occasional slower responses up to half a second.

By protocol

The protocol breakdown shows that the majority of records use the mcp protocol, with 63,881 total records. Of these, 32,130 are checkable, 23,109 are live, and 8,650 are unavailable. The a2a protocol has 2,822 records, nearly all checkable at 2,819, with 2,230 live and 533 unavailable. The http protocol is less common, with 18 records all checkable, 11 live, and 6 unavailable. Lastly, the openapi protocol has 10 records, all checkable, 6 live, and 3 unavailable.
