Using Codex

Codex's web-API is documented: Here This document will show you several useful API calls.

Debug

An easy way to check that your node is up and running is:

curl --request GET \
  --url http://localhost:8080/api/codex/v1/debug/info

This will return a JSON structure with plenty of information about your local node. It contains peer information that may be useful when troubleshooting connection issues.

Upload a file

Warning Once you upload a file to Codex, other nodes in the testnet can download it. Please do not upload anything you don't want others to access, or, properly encrypt your data first.

curl --request POST \
  --url http://localhost:8080/api/codex/v1/data \
  --header 'Content-Type: application/octet-stream' \
  -T <FILE>

On successful upload, you'll receive a CID. This can be used to download the file from any node in the network.

Download a file

When you have a CID of data you want to download, you can use the following:

curl --request GET \
  --url http://localhost:8080/api/codex/v1/data/{CID HERE}/network

Note that Codex does not store content-type or extension information.

Local data

You can view which datasets are currently being stored by your node.

curl --request GET \
  --url http://localhost:8080/api/codex/v1/data

Create storage availability

In order to start selling storage space to the network, you must configure your node with the following command. Once configured, the node will monitor on-chain requests-for-storage and will automatically enter into contracts that meet these specifications.

curl --request POST \
  --url http://localhost:8080/api/codex/v1/sales/availability \
  --header 'Content-Type: application/json' \
  --data '{
	"totalSize": "8000000",
	"duration": "7200",
	"minPrice": "10",
	"maxCollateral": "10"
  }'

For descriptions of each parameter, please view the Spec.

Purchase storage

To purchase storag space from the network, first you must upload your file. Once you have the CID, use the following to create a request-for-storage contract.

curl --request POST \
  --url http://localhost:8080/api/codex/v1/storage/request/{CID HERE} \
  --header 'Content-Type: application/json' \
  --data '{
  "duration": "3600",
  "reward": "1",
  "proofProbability": "3",
  "nodes": 2,
  "tolerance": 1,
  "collateral": "5",
  "expiry": "1711703406"
}'

For descriptions of each parameter, please view the Spec.

On successful, this request will return a Purchase-ID.

View purchase status

Using a Purchase-ID, you can check the status of your request-for-storage contract:

curl --request GET \
  --url http://localhost:8080/api/codex/v1/storage/purchases/{PURCHASE ID HERE}
