How it works

Three steps. One trust score.

Kevros Passport turns your agent's governance history into a single, verifiable trust score. No self-reporting. No checklists. Built from observed behavior.

01
Connect
Integrate the Kevros SDK or call the gateway API. Every governance call your agent makes — verify, attest, bind — automatically builds its trust history.
02
Score
Kevros computes a 0-100 trust score from real decisions. Governance calls, attestation integrity, outcome tracking, and consistency all contribute. The score updates with every interaction.
03
Display
Embed a live trust badge in your agent README, marketplace listing, or registry entry. The badge reflects your agent's current score and updates automatically.
Live badge

One line. Instant trust signal.

Embed a live Kevros Passport badge anywhere Markdown or HTML is supported. The badge pulls your agent's current trust score and tier in real time.

Replace {agent-id} with your agent's registered ID. The badge returns an SVG with your current score and tier. Updates on every governance call.

Score composition

What builds your score.

Kevros Passport scores are computed from four observable dimensions of agent behavior. No self-assessment. No questionnaires. Every data point comes from actual governance interactions.

Governance Decisions
Every verify call contributes. Agents that consistently submit actions for governance review — and receive ALLOW decisions — build trust. High deny rates lower the score.
Attestations
Signed attestation records in the provenance chain demonstrate that your agent produces verifiable evidence of its actions. More attestations, stronger trust signal.
Outcome Tracking
Bind and verify-outcome calls close the governance loop. Agents that track whether their actions achieved the intended result score higher than those that fire and forget.
Consistency
Sustained governance participation over time. A streak of consecutive days with governance activity demonstrates reliability. Gaps reduce the consistency component.

“Trust is not declared. It is observed.”

Trust tiers

Three tiers. Clear boundaries.

Every agent is classified into one of three trust tiers based on its current score. Tiers update in real time as governance interactions accumulate.

Trusted
80 – 100
High governance participation. Strong attestation history. Consistent outcome tracking. This agent has a sustained record of responsible behavior verified through cryptographic evidence.
Moderate
50 – 79
Active governance participation with room for improvement. May have gaps in attestation coverage, inconsistent outcome tracking, or a developing history. Building trust.
Low Trust
0 – 49
Limited governance history, high deny rates, broken evidence chains, or insufficient outcome tracking. This agent has not yet demonstrated trustworthy behavior through governance evidence.
Score transparency
Passport scores are computed from on-chain governance evidence. The score methodology is deterministic and auditable. No opaque models. No hidden weights. Scores reflect exactly what the governance record contains.
