How this service works
Reputation scoring with linear trust decay: after its first week a score loses 2-5 points a week by risk cluster (none for a sanctions-flagged entity), plus a bonus of up to 5 points for repeat verifications.
Output
Returns a numeric reputation score (0-100), a confidence value (0-1), a trend indicator (e.g. 'stable', 'declining', 'improving'), and a verification count reflecting how the entity's trust has evolved over time under Bayesian decay modeling.
Example use cases
Example prompt
“What's the Bayesian reputation score and trust trend for 'Acme Logistics BV' — they're currently in the 'high-risk' cluster with a trust score of 62, last verified 30 days ago with 5 verifications on record?”
Technical details
Endpoint
POSThttps://api.limitguard.ai/v1/reputation/score?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have prior trust data for an entity (existing trust score, cluster, and verification history) and need a temporally-decayed, Bayesian-updated reputation score with a confidence interval and trend — rather than a fresh full entity check from scratch. Ideal for periodic re-scoring of known counterparties rather than first-time entity lookups.
Side effects
- Missing required fields (entity_name, trust_score, cluster, last_verified_at) returns a 400 validation error
- Invalid trust_score outside 0-100 range may cause computation errors
- Very old last_verified_at timestamps may result in heavily decayed scores near zero
- Unknown cluster assignments may produce lower confidence intervals
- Service unavailable returns 503; payment issues return 402
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| cluster | string | Current cluster assignment. Send with trust_score to skip auto-computation |
| country | string | ISO 3166-1 alpha-2 country code. Required unless trust_score and cluster are both sent; the score is then computed from sanctions and jurisdiction |
| agent_id | string | ERC-8004 agent ID for verification |
| entity_name | string | Legal entity name |
| trust_score | integer | Latest trust score (0-100). Send with cluster to skip auto-computation |
| last_verified_at | number | Unix timestamp of last verification (defaults to now) |
| verification_count | integer | Times entity verified |
