Ratings & methodology

How Probegrade scores agent data.

Every listed source is called by automated probes on a fixed schedule. Scores come from those measurements, not from reviews, surveys or payments.

Signals

Five things we measure.

Uptime

Share of scheduled probes that succeed.

Latency

Median response time of successful probes.

Schema validity

Whether responses match the documented shape, so agents don't break on surprises.

Freshness

How current the returned data is versus what the source claims.

Price

Cost per call relative to comparable sources.

The score

Signals combine into a 0–100 Probegrade score. The exact weights are kept private so the score can't be gamed.

Independence

Our disclosure policy.

Sponsorship never changes scores

Providers can buy sponsored placement. It is always labeled “Sponsored”, shown apart from organic results, and has no effect on scores or ranks.

Verified is identity, not quality

The paid Verified badge confirms who runs a source. It does not raise a score.

Audit trail

Every probe is written to a hash-chained archive. Each monthly edition lists the archive head hash so it can be checked.

Public summary, paid detail

Summary scores are public. Probe-level history and detailed breakdowns are part of paid plans.
