The Indexers overview listed Alchemy as "most popular choice on Ethereum; now in talks to expand their service to Stellar, with a targeted launch in the first half of 2026." That's out of date — Alchemy's Stellar Data API is live.

This updates the entry to describe the actual offering: indexed transfer history, account balances, and NFT holdings across native, Stellar Classic, and Soroban assets (queryable without running your own indexer), and links Alchemy's Stellar Data API overview. It also cross-links Alchemy's Stellar JSON-RPC and the existing RPC providers entry, since Alchemy offers both the Chain/RPC API and the (indexer-style) Data API.

Sourced from Alchemy's own docs.

The entry described Alchemy as "in talks to expand to Stellar, targeted H1
2026." Alchemy's Stellar Data API has launched, so this updates the entry to
the actual offering (indexed transfer history, account balances, and NFT
holdings across native, Classic, and Soroban assets) with links to Alchemy's
Data API overview and JSON-RPC quickstart.

  • Adds links to Alchemy’s Stellar Data API overview and Stellar JSON-RPC quickstart.
  • Cross-links to the existing RPC providers list.

In the biz, these are called _Portfolio APIs._ Well-known companies offering them:

- [Alchemy]: most popular choice on Ethereum; now in talks to expand their service to Stellar, with a targeted launch in the first half of 2026.
- [Alchemy]: a widely-used data provider (popular on Ethereum), now live on Stellar. Its [Stellar Data API](https://www.alchemy.com/docs/reference/stellar-data-api-overview) serves indexed **transfer history**, **account balances**, and **NFT holdings** across native, Stellar Classic, and Soroban assets — letting you query this data without running your own indexer (JSON request bodies, opaque `pageKey` pagination). Alchemy also provides [Stellar JSON-RPC](https://www.alchemy.com/docs/reference/stellar-api-quickstart) and appears in the [RPC providers](../apis/rpc/providers.mdx) list.

i think the verbiage we landed on somewhere previously was "stellar assets" and "contract tokens"? (source)

let's use similar wording here maybe?

We could probably replace Stellar JSON-RPC with Stellar RPC to be more consistent with the rest of the documentation. i don't think we use the full JSON-RPC anywhere else (maybe except a page where we're saying the rpc service is built around json-rpc?)
