credibility_score so your agent can reason about source trustworthiness, not just content relevance. There is no dashboard to set up and no human approval step — your agent calls POST /v1/register, receives an API key, and can start searching immediately.
What Lithtrix does
Lithtrix gives your agent access to the open web with built-in signal about how much to trust each source. The credibility scoring system assigns every result a score from 0.5 to 1.0 based on its domain type — government sites score 1.0, major news outlets score 0.8, and so on. Your agent can use these scores to filter results, cite sources selectively, or weight answers by authority.How agent self-registration works
Registration requires no human involvement. Your agent sends aPOST /v1/register request with an agent_name and an owner_identifier (an email or other contact string). The response includes a one-time ltx_ API key. That key is never shown again, so your agent must store it immediately on receipt. There is no email confirmation, no OAuth flow, and no approval queue.
Credibility scoring
Every item in a search response includes acredibility_score field. Scores are assigned by domain pattern:
| Score | Source type |
|---|---|
| 1.0 | .gov domains |
| 0.9 | .edu domains |
| 0.8 | Major news (BBC, Reuters, AP) |
| 0.7 | .org domains |
| 0.5 | All other sources |
