info:
title: Helius API Catalog Addresses Funding 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.
