A visit is an observation in which GAIP sent a request (reachable recorded as true or false); observations where GAIP sent nothing (withdrawn, opted out, robots.txt refused, not active in its source) are not visits. Reachable: the host answered with any HTTP status. A successful handshake is a reachable visit with an HTTP 2xx answer (MCP: the initialize answer; A2A: the agent card), with its response time in milliseconds. Per cell: the share of visits reachable; the share of agents with at least one visit that were reachable on at least 95% of their visits; the p50 and p95 response time of successful handshakes (nearest rank). Cells: protocol MCP, A2A or both, for all public agents GAIP watches and for the frozen reference panel AGENTS-COHORT-2026-10. A cell is shown when it has at least 5 agents (response times: 5 agents with a successful handshake) and any count under 5 is withheld. GAIP's own agents, hosts read because an outside caller asked about them, and withdrawn or unpublished agents are left out. A month runs from the Monday of its earliest ISO week to the Monday after its last (as the Agent Web Index) and is frozen once that window ends; the current block covers the last 30 days and is rebuilt hourly. GAIP keeps the newest 60 raw observations of each agent, so an agent visited more often than that in a window counts its newest 60.
