Fix NFT contracts endpoint path in getNftContractsByAddress

[Copilot]

The fetchNftContractDataByMultichainAddress tool was hitting the wrong Alchemy endpoint — using /assets/nfts/by-address (the NFT ownership endpoint) instead of /assets/nfts/contracts/by-address, silently returning NFT items instead of collection/contract data.

Change

In api/alchemyApi.ts, getNftContractsByAddress now calls the correct Portfolio API path:

- const response = await client.post('/by-address', { ...params });
+ const response = await client.post('/contracts/by-address', { ...params });

createNftClient() base URL remains https://api.g.alchemy.com/data/v1/${API_KEY}/assets/nfts, so the resolved URL becomes …/assets/nfts/contracts/by-address as documented.

Other endpoints verified (no changes needed)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
