Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.
Install — reproduced in a container Oct 15, 2026
Runtime: Python 3.10–3.13
pip install uagents
from uagents import Agent, Context
agent = Agent(name="alice", seed="<recovery phrase>")
@agent.on_interval(period=2.0)
async def hello(ctx: Context): ctx.logger.info('hi')
agent.run()You supply: optional seed phrase to pin the agent address/wallet (else a key is written to private_keys.json)

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 37 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
Last 30 days — to 2026-10-24, one point per UTC day
A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
