+**The Graph:** Endpoints require authentication (API key / authorization header). Use the form `https://gateway.thegraph.com/api/<API_KEY>/subgraphs/id/<SUBGRAPH_ID>`.
+
+**Goldsky:** Endpoints are public with 50/10s per-IP rate limits — no authentication required for queries.
+
+Provider support per network is configured via `graphNode.supported` and `goldsky.supported` in each network config file.

 ### Deployment
 
+#### The Graph Studio
+
 ```bash
-# Deploy to The Graph Studio (requires auth token)
 # Set your deployment key first:
 # npx graph auth --studio <DEPLOY_KEY>
 
 # Deploy specific network
 DEPLOYMENT=erc-8004-eth-sepolia npm run deploy
 
 # Deploy to Graph Studio (recommended; lets you set a release label)
-# STUDIO_SLUG=<your-studio-subgraph-slug> DEPLOYMENT=erc-8004-eth-sepolia VERSION_LABEL=<your-release-label> npm run deploy:studio
+STUDIO_SLUG=<your-studio-subgraph-slug> \
+DEPLOYMENT=erc-8004-eth-sepolia \
+VERSION_LABEL=<your-release-label> \
+npm run deploy:studio
 
 # Or deploy locally for testing
 npm run create-local && npm run deploy-local
 ```
 
+#### Goldsky
+
+Goldsky provides backwards-compatible subgraph hosting with improved performance and reliability. Goldsky also has public-query endpoints, allowing you to query the subgraph without authentication, making Goldsky endpoints ideal for agentic applications.
+
+**Prerequisites:**
+- Install Goldsky CLI: `curl https://goldsky.com | sh`
+- Obtain an API token from your [Goldsky Project Settings](https://app.goldsky.com) page
+
+**Important:** Unlike The Graph, Goldsky requires you to build before deploying. The deploy scripts handle this automatically. Also, Goldsky uses unique `name/version` pairs — redeploying the same version will error. Bump the `VERSION` or use tags to manage releases.
+
+```bash
+# Deploy a single network to Goldsky
+GOLDSKY_TOKEN=<your-token> \
+DEPLOYMENT=erc-8004-eth-sepolia \
+VERSION=1.0.0 \
+npm run deploy:goldsky
+
+# Deploy with a tag (e.g., "prod") for stable endpoints
+GOLDSKY_TOKEN=<your-token> \
+DEPLOYMENT=erc-8004-eth-sepolia \
+VERSION=1.0.0 \
+TAG=prod \
+npm run deploy:goldsky
+
+# Deploy ALL supported networks to Goldsky
+GOLDSKY_TOKEN=<your-token> \
+VERSION=1.0.0 \
+npm run deploy:goldsky:all
+
+# Update a tag to point to a new version (zero-downtime swap)
+goldsky subgraph tag create erc-8004-eth-sepolia/2.0.0 --tag prod --token $GOLDSKY_TOKEN
+```
