  title: Helius API Catalog Addresses Transfers API
  version: 1.0.0
  summary: Machine-readable discovery document for every Helius API surface on Solana.
  description: 'This document is a discovery catalog — not an operational spec. It exists so

    AI agents, codegen tools, and SDK generators can locate the canonical

    OpenAPI document for every Helius API in one request instead of crawling

    the docs site.


    Start with the `x-apis` array: each entry links a Helius API surface to its

    canonical OpenAPI spec (`specUrl`) and human-readable docs (`docsUrl`).

    Follow `externalDocs` for the full developer documentation site.


    ## A note on JSON-RPC APIs


    Several Helius APIs (Solana RPC, DAS, Sender, Mint, Priority Fee,

    ZK Compression) follow the JSON-RPC 2.0 convention where every method POSTs

    to `/` with a `method` field in the request body. For each such API the

    repository ships both per-method fragment YAMLs (used to render the

    Mintlify reference pages) and an auto-generated `_combined.yaml` that

    merges every method into a single OpenAPI document. In the combined

    documents, colliding paths are disambiguated with a URL-fragment suffix

    (e.g. `/#getAccountInfo`) and each operation carries an `x-actual-path`

    extension that records the real request path (`/`). The fragment syntax is

    schema-only — real calls still go to the `url` in `servers`.


    All `specUrl` values below point to raw GitHub files on the `main` branch

    of `helius-labs/docs`. They are stable URLs suitable for downstream tools

    to pin or fetch.
