Fetch ENS-hosted lists via eth.limo instead of the wispy-bird worker proxy - #3310

Conversation
…proxy The wispy-bird-88a7 Cloudflare worker is an open HTTP proxy (fetches any ?url= target) that we want to decommission as a security hole. It was only needed because *.eth.link lacked usable CORS headers; eth.limo serves ENS content with access-control-allow-origin: * so no proxy is needed. The proxy path is also currently broken: every ENS list on the site returns 403 through it today, while 11/13 return 200 via eth.limo (the other two, tokenlist.dharma.eth and tokenlist.zerion.eth, are dead ENS names that fail on both paths).

Verified in the Vercel preview vs production, full network capture from both: ENS lists (the 13 this PR touches):
Non-ENS lists (21, untouched by this PR): identical results on prod and preview — same 10 work, same 11 fail either way ( So every tile still broken in the preview is broken on production today for reasons unrelated to the proxy. A registry prune of the dead lists would be a sensible follow-up. |

Why
wispy-bird-88a7.uniswap.workers.devis an open HTTP proxy (it fetches any?url=target) deployed in Aug 2020 solely because*.eth.linklacked usable CORS headers. Security wants to decommission it (1.2M req/mo, largely abuse). eth.limo serves ENS content withaccess-control-allow-origin: *, so the site can fetch lists directly.What's already broken
The proxy path currently returns 403 for every ENS list on the site, so ENS lists appear to be broken in production today. Via eth.limo, 11 of 13 return 200 with valid JSON. The two failures (
tokenlist.dharma.eth,tokenlist.zerion.eth) are dead ENS names that fail through the proxy as well — candidates for removal from the registry in a follow-up.Changes
getListURLFromListID:https://<name>.eth.limoinstead of the worker proxygetURLFromQuery(list page): sameCompanion PR in Uniswap/data switches the tokenlists scraper the same way. Once both land, the worker can be killed (or first restricted to
*.eth.linktargets during a deprecation window for third-party users who hardcode it).🤖 Generated with Claude Code
