API Reference

Skip:Connect

Research

Jobs

Submit a signed base64 encoded transaction to be broadcast to the specified network. On successful submission, the status of the transaction and any subsequent IBC or Axelar transfers can be queried through the /status endpoint.

Post /v2/tx/submit

Error detail: 
* `LOW_INFO_ERROR` - Not enough asset pricing information to determine the price safety of the route.
* `BAD_PRICE_ERROR` - The execution price of the route deviates significantly from the current market price.

How to Embed iframe Widget

Get all supported chains along with additional data useful for building applications + frontends that interface with them (e.g. logo URI, IBC capabilities, fee assets, bech32 prefix, etc...)

Get /v2/info/chains

Get /v2/info/bridges

Get /v2/fungible/venues

Get supported assets. Optionally limit to assets on a given chain and/or native assets.

Get /v2/fungible/assets

Get assets that can be reached from a source via transfers under different conditions (e.g. single vs multiple txs)

Post /v2/fungible/assets_from_source

This supports cross-chain actions among EVM chains, Cosmos chains, and between them. Returns the sequence of transfers and/or swaps to reach the given destination asset from the given source asset, along with estimated amount out. Commonly called before /msgs to generate route info and quote.

Post /v2/fungible/route

This supports cross-chain actions among EVM chains, Cosmos chains, and between them. Returns minimal number of messages required to execute a multi-chain swap or transfer. Input consists of the output of route with additional information required for message construction (e.g. destination addresses for each chain)

Post /v2/fungible/msgs

This supports cross-chain actions among EVM chains, Cosmos chains, and between them. Returns minimal number of messages required to execute a multi-chain swap or transfer. This is a convenience endpoint that combines /route and /msgs into a single call.

Post /v2/fungible/msgs_direct

Request asset recommendations for the given source assets on a given destination chain. The response includes recommended destination assets and recommendation reasons.

Post /v2/fungible/recommend_assets

Get origin assets from a given list of denoms and chain IDs.

Post /v2/fungible/ibc_origin_assets

Given 2 chain IDs, returns a list of equivalent assets that can be transferred

Post /v2/fungible/assets_between_chains

Requests tracking of a transaction that has already landed on-chain but was not broadcast through the Skip Go API. The status of a tracked transaction and subsequent IBC or Axelar transfers if routing assets cross chain can be queried through the /status endpoint.

Post /v2/tx/track

Get the status of the specified transaction and any subsequent IBC or Axelar transfers if routing assets cross chain. The transaction must have previously been submitted to either the /submit or /track endpoints.
