Network-level, key-based platform linking

A system comprising:

• an intermediary platform;
• and
• a set of member platforms within member computing ecosystem communicatively connected to the intermediary platform, wherein the intermediary platform comprises one or more processors;
• and one or more memories storing processor-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, originating from a terminal, an exchange request comprising a universally unique ephemeral key (UUEK), wherein the UUEK comprises a first member partition corresponding to a first member platform within the member computing ecosystem and an exchange identifier;
• identifying, using a first internal service corresponding to the first member partition, a local data construct of a cross-platform data object based on the UUEK, wherein the local data construct comprises a first member-specific identifier corresponding to the first member platform and a second member-specific identifier corresponding to a second member platform;
• providing a value request to a second internal service corresponding to the second member platform, wherein the value request comprises the second member-specific identifier and at least a portion of the exchange request;
• receiving, based on a contribution ruleset corresponding to the second member platform, an updated exchange request from the second internal service;
• providing an adjusted authorization request to the first member platform based on the updated exchange request;
• receiving, from the first member platform, an authorization response based on the adjusted authorization request;
• and
• providing the authorization response to the first internal service and the terminal.

One or more non-transitory computer-readable media storing processor-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, originating from a terminal, an exchange request comprising a universally unique ephemeral key (UUEK), wherein the UUEK comprises a first member partition corresponding to a first member platform within a member computing ecosystem and an exchange identifier;
• identifying, using a first internal service corresponding to the first member partition, a local data construct of a cross-platform data object based on the UUEK, wherein the local data construct comprises a first member-specific identifier corresponding to the first member platform and a second member-specific identifier corresponding to a second member platform;
• providing a value request to a second internal service corresponding to the second member platform, wherein the value request comprises the second member-specific identifier and at least a portion of the exchange request;
• receiving, based on a contribution ruleset corresponding to the second member platform, an updated exchange request from the second internal service;
• providing an adjusted authorization request to the first member platform based on the updated exchange request;
• receiving, from the first member platform, an authorization response based on the adjusted authorization request;
• and
• providing the authorization response to the first internal service and the terminal.
