# API Reference

Endpoint reference for the Titan Developers Portal API.

The Developers Portal exposes four endpoints at `https://portal.api.titan.exchange`. All are `GET`, authenticate with the `x-api-key` header, and return JSON or MessagePack according to the `Accept` header.

| Endpoint             | Returns                                    | Reference                                                                                        |
| -------------------- | ------------------------------------------ | ------------------------------------------------------------------------------------------------ |
| `/api/v1/quote/swap` | Quoted routes with executable instructions | [Quote Swap](/titan/developer-doc/developers-portal/reference/quote-swap.md)                     |
| `/api/v1/info`       | Protocol version and parameter bounds      | [Info](/titan/developer-doc/developers-portal/reference/info-venues-providers.md#info)           |
| `/api/v1/venues`     | Venue labels and program IDs               | [Venues](/titan/developer-doc/developers-portal/reference/info-venues-providers.md#venues)       |
| `/api/v1/providers`  | Providers currently quoting                | [Providers](/titan/developer-doc/developers-portal/reference/info-venues-providers.md#providers) |

Parameters and response types are shared with Titan Gateway. The Portal accepts every parameter as a flat query-string value; the [Swap API reference](/titan/developer-doc/swap-api/reference/gateway/gateway-quote-swap.md) documents the same fields alongside Titan Direct's nested request objects.

{% hint style="info" %}
`/api/v1/quote/price` and the WebSocket endpoint `/api/v1/ws` are not available on the Portal. Streaming quotes are provided by [Titan Direct](/titan/developer-doc/swap-api/reference/direct.md), an [Enterprise](/titan/developer-doc/developers-portal/plans-rate-limits-credits.md#enterprise) feature currently delivered through distributors.
