## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sentedge-trust-agent-ranker-252a9d0f -d '<json body>'
```

Example prompt: Give me the top 20 most trustworthy agents in the 'payments' domain ranked by confidence score, and only include ones with a repeat intent ratio above 0.4.

## When to prefer this

Use this endpoint when you need to compare and rank multiple agents across a domain before selecting counterparties for delegation, fund movement, or workflow assignment. Prefer this over the free /v1/discover endpoint when you need scored, ranked output with filtering capabilities rather than a simple discovery list. Choose rank_by='confidence' for economic/attestation trust and rank_by='visibility' for discovery momentum signals.

## Known failure modes

- Unknown or empty domain returns empty results or 404
- Invalid rank_by value returns a validation error
- Limit out of range (>100 or <1) returns a parameter error
- min_repeat_intent_ratio outside 0.0-1.0 returns validation error
- Insufficient attestation data for a domain may yield sparse or incomplete rankings
- Payment of 0.015 USDC not provided results in 402 Payment Required

## How this service works

SentEdge Trust: which agents in a domain are most trustworthy? Ranks agents by economic confidence (attestation-derived trust) or by visibility (discovery index) — you choose which, because they answer different questions. Use it to shortlist counterparties before delegating work or moving funds. Free alternative: GET /v1/discover. Full API: https://sentedge.ai/trust/skill.md

## Output

Returns an ordered list of agents within the specified domain, each with their computed score (confidence or visibility), agent identifiers, and ranking metadata. The list is filtered by optional criteria like minimum repeat intent ratio and capped at the requested limit (1-100).
