Here is the code for Oikos's current subgraph: https://thegraph.com/explorer/subgraph/oikos-cash/oikos
The Graph exposes a GraphQL endpoint to query the events and entities within the Oikos system.
For example:
// Fetch all Exchanges in the last 24hrs (uses "fetch" - runs in the browser)
(async () => {
const ts = Math.floor(Date.now() / 1e3);
const oneDayAgo = ts - 3600 * 24;
const body = JSON.stringify({
query: `{
synthExchanges(
orderBy:timestamp,
orderDirection:desc,
where:{timestamp_gt: ${oneDayAgo}}
)
{
fromAmount
fromCurrencyKey
toCurrencyKey
block
timestamp
toAddress
}
}`,
variables: null,
});
const response = await fetch(graphAPI, {
method: 'POST',
body,
});
const json = await response.json();
const { synthExchanges } = json.data;
// ...
})();
