Getting upload status

The service provides a few ways to check on the status of an upload.

On the Account page of the site, you can see a list of files that you've uploaded to

The table on the account page has two columns related to the current status of the data storage process, Complete file? and Storage Providers.

The information in the account page file list is also available using the JavaScript client's status method, via the HTTP API by sending a GET request to the /status/{cid} endpoint, or using the w3 status <cid> command on the CLI.

Complete file?

When you upload data to Web3.Storage, there might be some situations when an upload did not successfully complete. If you intended to upload a file, the Complete file? column shows whether we received a complete graph of data. There are four possible values for the column: Complete, Pinning, Pinned, and Failed.

A Complete status means that we have received a complete graph of data.

A Pinned status is a legacy status from our previous architecture. It is equivalent to the Complete status.

The Pinning status indicates that the completeness of the graph of data is still being validated.

If you have a large upload with many blocks (e.g., a directory for your 10K NFT drop), currently might report the status as Pinning indefinitely. This is because the upload was too large for us to validate that the upload is a complete graph. You can verify that your upload is complete by spot checking individual files in your upload and making sure they're available via w3link (i.e.,

A Failed status indicates that the graph of data is incomplete. For older uploads, it can also mean an operation failed while our infrastructure was attempting to pin the data. A Failed pin will change to Pinned if the same data is uploaded successfully in a subsequent request. As long as the CID is the same for both uploads, the original upload's status will be marked as Pinned after a small delay.

There are several reasons why an upload may end up in the Failed state.

If you uploaded your data directly to the Web3.Storage service using a client library, the HTTP API, or the Upload files button on the website account page, a Failed status may indicate that one or more chunks of data was not received by the service. This may happen when uploading large files or directories containing many files and may be resolved by retrying the upload.

If your data was pinned using the Pinning Service API, a Failed status usually means that we weren't't able to fetch the complete content over the IPFS peer-to-peer network. These issues can be hard to diagnose due to the many variables involved, especially when the original source of the data may have an unreliable connection to the network or is behind a firewall. If the data is being provided by another pinning service such as Pinata, or if you've verified that the data is retrievable using IPFS (ideally from multiple distinct locations), please file an issue so we can look into the cause.

Please note that this column validates that the data received is a complete graph of data. For specific use cases, you might might be intentionally not be sending a complete graph of data (e.g., diffing). If this is the case, you can ignore this column.

If you find that your file is retrievable but the pin status still says Failed, please file an issue with the relevant CIDs and we'll take a look.

Storage providers

The Storage Providers column on the file listing page shows information about the Filecoin storage providers that have committed to long-term storage deals for the uploaded data.

When data is first uploaded, the Storage Providers column will show a status of Queuing. This indicates that the service has the data and is aggregating it into a format that can be used to make a storage deal.

Once enough data has been aggregated, the service will propose several Filecoin storage deals with different Filecoin storage providers. These will initially be shown in a Pending status, while the provider accepts the deal and posts its commitment to the Filecoin blockchain.

When using the HTTP API or client library to check the upload status, information about Filecoin storage is provided in the deals array field within the status response object. The deals array will be empty while the upload is in the Queuing state.

Once storage deals have been proposed, the deals array will contain JSON objects describing each deal. Each object has a status field, which will have a value of "Queued" when the deal is pending. When the deal has been confirmed and published to the Filecoin blockchain, the status field will have a value of "Active".

Storage deal schema:

dealIdOn-chain ID of the deal.
storageProviderAddress of the provider storing this data.
statusCurrent deal status: "Queued" "Published" "Active"
pieceCidFilecoin Piece CID of the data in the deal.
dataCidCID of the data aggregated in this deal.
dataModelSelectorSelector for extracting stored data from the aggregated data root.
activationDate when the deal will become active in ISO 8601 format.
createdCreated date in ISO 8601 format.
updatedUpdated date in ISO 8601 format.

Example JSON for an active storage deal:

  "dealId": 2229885,
  "storageProvider": "f01278",
  "status": "Active",
  "pieceCid": "baga6ea4seaqawvtpgovz222raqk6zgawvjz4kjnnl7i3pduovtuivl2qxokoaji",
  "dataCid": "bafybeigiytbwooh2ei74k6z4h7zqgo7y7rxx3zanlg4whd4g37rhh6o74m",
  "dataModelSelector": "Links/100/Hash/Links/0/Hash/Links/0/Hash",
  "activation": "2021-08-05T22:24:00+00:00",
  "expiration": "2022-12-28T22:24:00+00:00",
  "created": "2021-08-04T00:35:43.492403+00:00",
  "updated": "2021-08-09T06:16:44.047003+00:00"

You can verify the status of your upload on the Filecoin blockchain at any time after the initial storage deals are made. Once a deal is active, you'll find links to the deal information in the Storage Providers column on the account page file list. These will take you to the Filfox block explorer, which shows details of every Filecoin message and transaction. You can also use the information from the JSON deals object described above to retrieve deal information using native Filecoin software like Lotus.
