# 4.5 Supply info api for Cosmos chain

 

## Supply info api

[https://api-supply.memenetwork.io](https://api-supply.memenetwork.io/)

This is an advanced supply information API for Cosmos Chain. I simplified the logic structure to improve efficiency and enable automatic switching in case of API\_ENDPOINT failure.

This improves the reliability and stability of the supply information API by quickly switching to the next API\_ENDPOINT when the first one fails.

```
{
  "apr": 68.31957987369881,
  "totalSupply": 11997255843.06718,
  "circulatingSupply": 11296519548.811697,
  "communityPool": 700723521.8232318,
  "totalStaked": "6146166417.423682",
  "bondedRatio": 0.5122982322886627,
  "denom": "MEME"
}
```

### Other routes

－ `/v1/total-supply`: returns total supply in plain text

－ `/v1/circulating-supply`: returns circulating supply in plain text

－ `/v1/total-staked`: returns total staked in plain text

－ `/v1/bonded-ratio`: returns bonded ratio in plain text

－ `/v1/community-pool`: returns community pool size in plain text

－ `/v1/apr`: returns APR in plain text

－ `/v1/denom`: returns denom in plain text

－ `/v1`: JSON

#### How circulating supply is calculated

1. Get total supply.
2. Get community pool.
3. Subtract community pool from total supply.

This yields the circulating supply.

### environment variable

See `.env.example` for an example.

eg:

```
INTERVAL=120000 # if INTERVAL = 60000 = 60s cache, 
PORT=3010
API_ENDPOINT1=https://meme-api.polkachu.com
API_ENDPOINT2=https://api-meme-1.meme.sx
API_ENDPOINT3=https://meme.api.m.anode.team
COIN_DENOM=umeme
COIN_DECIMALS=6
DENOM=MEME
```
