## Discover models

# Read the public model catalog

No authentication or payment is required. HTTP 200 returns a JSON array,
not an OpenAI object/list envelope; an empty array is valid. Each model has
`id`, `protocols`, `context_length`, `max_output_tokens`, `input_per_1m`,
and `output_per_1m`. Prices are USD per **million** tokens as decimal
strings. Optional fields include aliases, cache prices, and `free`.

Use an offered model with the desired protocol; do not copy old fixture
prices. On HTTP 429, respect `Retry-After`. Browser cross-origin access
requires verified CORS.

```sh
curl -sS https://api.agentrouter.cc/v1/models
```
