Querying Indexer Provider

How to query an indexer provider

An indexer node can be queried over HTTP or libp2p for a multihash or a payload CID.
Using payload CID
GET request
GET /cid/<cid>
Curl request
curl  https://<INDEXER NODE ADDRESS>/cid/<payload CID>
curl https://cid.contact/cid/bafybeigvgzoolc3drupxhlevdp2ugqcrbcsqfmcek2zxiw5wctk3xjpjwy
Query using the multihash
GET request
GET /mh/<multihash
Curl request
curl  https://<INDEXER NODE ADDRESS>/mh/<multihash>
curl https://cid.contact/multihash/QmcgwdNjFQVhKt6aWWtSPgdLbNvULRoFMU6CCYwHsN3EEH
POST Request
POST /mh
The body for the POST request can be found here as a JSON.
Find command
Both storetheindex as well as index-provider binaries contain a find command that can be used to query the indexer nodes for a multihash or a payload CID.
provider find --help
storetheindex find --help
Go client library
The storetheindex repo also ships a client library that can be integrated in other programs to query the indexer nodes. The client library can be used to query the indexer nodes over HTTP as well as libp2p connections. 
This client library is also utilised by the find command in the storetheindex as well as index-provider binaries. Programmers can use these commands as reference implementations.
