# Trait Pricing Source

> Pluggable model pricing source interface.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-pii-redaction -p nemo-relay-ffi -p nemo-relay-types -p nemo-relay-plugin -p nemo-relay-worker-proto -p nemo-relay-worker`.

<pre />

Pluggable model pricing source interface.

Database, service-backed, or enterprise-managed model pricing integrations should implement this trait and return a validated catalog snapshot. The LLM hot path uses [`PricingResolver`](/reference/api/rust-library-reference/nemo-relay/codec/model_pricing/struct-pricingresolver), so sources can refresh out-of-band without making each response decode perform network or database I/O.

## Required Methods

#### `source_name`

<pre />

Stable source name for diagnostics.

#### `load_catalog`

<pre />

Loads a catalog snapshot from this source.
