every second / Streams
Streams & alerts

We push. You route.

Two streams, one event log. The public stream carries what the dashboard shows — scores, incidents with evidence, the index — for everyone. The evidence stream carries raw measurements, three-leg timings and webhooks — for an ecosystem's teams, through its foundation's partnership. Every incident is also published on X with the transaction that proves it.

WebSocket

A persistent stream per chain: every probe transaction with its timestamps, every incident as it opens and closes. The dashboard is a subscriber.

Signed webhook

A JSON POST to your URL — HMAC-signed, retried with backoff, idempotent by id. Point it at your pager, your runbook or your own bot.

REST API

Pull what the stream pushed: measurements, incidents, routes, scorecards. The same evidence, at rest.

Public feed on X

Every incident — opened and recovered — is posted publicly with its evidence transaction. Silent outages are not silent.

Signature & delivery

Every POST carries an X-ES-Signature header: HMAC-SHA256 of the body with your secret. Non-2xx responses are retried 5 times with exponential backoff (1 m → 30 m). Events are idempotent by id; the stream and the webhook carry the same ids.

Who receives what

Everyone receives the public stream and every incident on X, with evidence. Teams in a partnered ecosystem receive the evidence stream, the webhooks and the full API for their chains — provisioned by their foundation.
