DAPI Endpoints

Overview

DAPI currently provides 2 types of endpoints: JSON-RPC and gRPC. The JSON-RPC endpoints expose some layer 1 information while the gRPC endpoints support layer 2 as well as streaming of events related to blocks and transactions/transitions.

Platform Endpoints

In addition to providing the requested data, the following endpoints can also provide proofs that the data returned is valid and complete. The endpoints are versioned so updates can be made to them without introducing issues for endpoint consumers.

Contested Resources

Endpoint	Description
getContestedResources	Added in Dash Platform v1.0.0 Retrieves the contested resources for a specific contract, document type, and index.
getContestedResourceIdentityVotes	Updated in Dash Platform v5.0.0 Retrieves the voting record of a specific identity. Rejects a non-zero offset on proved requests.
getContestedResourceVotersForIdentity	Added in Dash Platform v1.0.0 Retrieves the voters for a specific identity associated with a contested resource.
getContestedResourceVoteState	Added in Dash Platform v1.0.0 Retrieves the state of a vote for a specific contested resource.
getVotePollsByEndDate	Retrieves vote polls that will end within a specified date range

Data Contracts and Documents

Endpoint	Description
getDataContract	Returns the requested data contract
getDataContracts	Updated in Dash Platform v5.0.0 Returns the requested data contracts. Rejects an empty ID list when a proof is requested.
getDataContractHistory	Updated in Dash Platform v5.0.0 Returns the requested data contract history. Returns INVALID_ARGUMENT for a limit outside 1 to 10, and rejects an offset on proved requests.
getDataContractsByRange	Added in Dash Platform v5.0.0 Enumerates every data contract on Platform, one page at a time, in ascending contract ID order.
getDataContractsLatestVersions	Added in Dash Platform v5.0.0 Returns the current version number of each requested data contract. Clients can use this to check whether contracts they already hold are still current without downloading the contracts again.
getContractFeePots	Added in Dash Platform v5.0.0 Returns the two fee pots of a data contract.
getDocuments	Updated in Dash Platform v5.0.0 Returns the requested document(s), or an aggregate count/sum/average over the matched document set. Includes ranked, having-range, chained, and composite query modes, the IN_TIME_RANGE and IN_INTEGER_RANGE window operators, and the CONTAINS / CONTAINS_ANY typed-array operators.
getDocumentHistory	Updated in Dash Platform v5.0.0 Returns the revision history for a single document on a contract that keeps document history. Rejects a non-zero offset on proved requests.

Contract Moderation

Added in version 5.0.0.

Contract moderation, introduced in protocol version 14, lets a data contract keep a banlist, a suspension list, and a warning list of identities, and lets its moderators delete documents. A contract’s moderators are its owner, identities it appoints, or a team elected by masternodes. A banned or suspended identity cannot submit document transitions for the contract. The endpoints in this section read an identity’s moderation status, the lists themselves, the records of removed documents, and the actions and action counts of an elected contract’s seated moderation team.

Endpoint	Description
getContractModerationStatus	Returns an identity’s status on one or more moderation lists of a moderated data contract: whether it is banned, until when it is suspended, and which warnings it carries.
getContractModerationEntries	Returns one page of a moderated contract’s banlist, suspension list, or warning list, in identity ID order.
getContractDocumentRemovals	Returns the removal records of documents that a contract’s moderators deleted from one document type, either for specific document IDs or as a page in document ID order. A record shows who removed the document, when, and why, and whether it has since been restored.
getContractTeamActions	Returns one page of the actions that an elected contract’s seated moderation team is voting on (active) or has carried out (closed), in action ID order.
getContractTeamActionSigners	Returns the team members that approved one of the actions an elected contract’s seated moderation team votes on.
getContractModerationActionCounts	Returns how many counted moderation actions (bans, suspensions, warnings, and document deletions) each member of an elected contract’s seated moderation team has signed since the moderators fee pot was last paid out.

Identities

Endpoint	Description
getIdentity	Returns the requested identity
getIdentityBalance	Returns the requested identity’s balance
getIdentityBalanceAndRevision	Returns the requested identity’s balance and revision
getIdentityByNonUniquePublicKeyHash	Updated in Dash Platform v5.0.0 Returns one or more identities associated with a public key hash, including for non-unique masternode keys. A v1 request returns one proof covering the index selection and the identity.
getIdentityByPublicKeyHash	Returns the identity associated with the provided public key hash
getIdentityContractNonce	Returns the identity contract nonce
getIdentityKeys	Updated in Dash Platform v5.0.0 Returns the requested identity keys. Request validation is stricter.
getIdentityKeysRemainingBudgets	Added in Dash Platform v5.0.0 Returns what is left of the credit budgets of an identity’s keys.
getIdentityNonce	Returns the current identity nonce
getIdentitiesBalances	Updated in Dash Platform v5.0.0 Retrieves the balances for a list of identities. Rejects an empty ID list when a proof is requested.
getIdentitiesContractKeys	Updated in Dash Platform v5.0.0 Returns keys associated to a specific contract for multiple Identities. Rejects an empty ID list when a proof is requested.

Security Groups

Added in version 2.0.0.

Security groups provide a way to distribute token configuration and update authorization across multiple identities. Each group defines a set of member identities, the voting power of each member, and the required power threshold to authorize an action. The endpoints in this section are used to retrieve information about groups and the actions they are performing.

Endpoint	Description
getGroupInfo	Retrieves information about a specific group within a contract, including its members and required power.
getGroupInfos	Retrieves information about multiple groups within a contract, including their members and required power.
getGroupActions	Updated in Dash Platform v5.0.0 Retrieves a list of actions performed by a specific group within a contract. Adds the mint_to_pool and burn_from_pool token events.
getGroupActionSigners	Retrieves the signers for a specified group action within a contract, along with their assigned power.

Contract Groups

Added in version 5.0.0.

From protocol version 14, contract groups organize data contracts, document types, and tokens into an identity-owned collection, which authentication keys can be scoped to. Each group has an owner, optional admins, and an optional name and description. Contract groups are not the same as security groups: security groups are defined inside a data contract and their member identities jointly authorize token actions, while the members of a contract group are contracts, document types, and tokens.

Endpoint	Description
getContractGroupInfo	Retrieves the stored information of a contract group: its owner, admins, name, and description.
getContractGroupMembers	Retrieves one page of a contract group’s members of a single kind: member contracts, member document types, or member tokens.
getContractGroupsForContract	Retrieves the contract groups a data contract belongs to, whether as a whole contract, through its document types, or through its tokens.
