SPIKE: GetOperation from Indexers

[Innkst]

As a Taquito user that has an Operation Hash I want an API that I can use to fetch the Operation so that I can inspect the contents and status of that Operation

Background

The Tezos RPC node does not offer the ability to fetch an operation by operation hash (May be inplemented in future see Tezos Issue 1131).

Note, this is a spike, aka a prototype of implementation

Acceptance criteria:

• Each of the below operation can be retrieved by hash using API for each of the indexers:
  • https://tezgraph.com/
  • https://api.tzkt.io/#tag/Operations
  • https://tzstats.com/docs/api/index.html
  • https://better-call.dev/docs
• Document operation properties available by each indexer api for each kind of operation, i.e. name, type, format and description.
• Propose a generalized list of properties based on the above discovery: name, type, format(i.e. unixepoch vs. UTC, etc.) and description
• Define TypeScript type definitions for the generalized properties for operations.

Examples (mainnet)

Transaction https://tzstats.com/oogJQZM1bHNSzJ6egr6dAFweERUTmJLTjR7Nf9XbNrjMkQbddSs/39721104 A transaction transferring 1 XTZ token from one implicit account to another

Batch Operation w/ Delegation and Reveal https://tzstats.com/onwbonv722FrR2m8isDPgCz4XzSmkC4oaQEHcFsYw3SLiPgKE7y A batch operation with a delegation operation and a reveal operation.

Findings added to the notion page Taquito indexer package for this spike

[Innkst]

tzKT API was changed recently and we want to review it. We will review it before starting the actual implementation.
