# SentEdge Trust Score (GET)

> SentEdge Trust Score (GET) is a paid API for AI agents from sentedge.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Returns a trust confidence score for a given agent identifier, combining signed bilateral attestations and a visibility signal with full component breakdowns, via GET query parameters.

## How to call it through Zero

```sh
zero fetch --capability sentedge-trust-score-get-87c4e65d
```

Example prompt: Can you check the SentEdge trust score for agent did:key:z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGpbnnEGta2doK in the 'finance' domain so I know whether to delegate a task to it?

## When to prefer this

Use this endpoint when you need a detailed, component-level trust score for a single agent and cannot issue a POST request (e.g., from a read-only agent or simple HTTP client). Prefer this over the free GET /v1/signals endpoint when you need full attestation-derived confidence breakdowns. Use the batch endpoint instead when you need to evaluate up to 10 agents in one call.

## Known failure modes

- Missing agent_id parameter returns a 400 validation error
- Unknown or unrecognized agent_id returns a score of 0 or empty attestation set
- Invalid agent ID format (not did:key, ERC-8004, or A2A) may return an error or zero-confidence result
- Payment of 0.01 USDC not made or failed results in 402 Payment Required
- Domain context not recognized may return a generic rather than domain-specific score

## How this service works

SentEdge Trust: is this agent trustworthy? Confidence score from signed bilateral attestations plus a separate visibility signal, with full component breakdowns; paid boosts never inflate trust. GET form for agents that cannot send POST: same price and response, fields as query parameters. Free alternative: GET /v1/signals. Full API: https://sentedge.ai/trust/skill.md

## Output

Returns a JSON object containing a numeric confidence score derived from signed bilateral attestations, a separate visibility signal, and a full breakdown of score components. The response does not include paid-boost inflation, giving an honest trust assessment.
