Summary

Adds Codex (codex.io) — a real-time blockchain data API — to three developer docs pages: Backend API libraries, JavaScript API libraries, and Data & Analytics.

Legitimacy Check

Codex Data Inc. (founded 2020) is a credible project: backed by Version One, Alliance, Tribe Capital, Mark Cuban, and Balaji Srinivasan. Notable customers include TradingView, Coinbase, Uniswap, Sudoswap, and Magic Eden. Active GitHub org (Codex-Data) with a published npm SDK (@codex-data/sdk).

Disclosure: PR author appears to be employed at Codex Data Inc. Self-promotional PRs are common for these listing pages but worth noting.

Formatting

All three entries follow existing markdown patterns correctly. No issues with structure or link formatting.

Concerns

#	Severity	Issue
1	Medium	Questionable fit for the JavaScript API libraries page. That page lists actual JS libraries you install and call (web3.js, ethers.js, viem). Codex is a data API service. They do have an SDK, but the entry doesn't even link to it — it links to generic docs/explorer/GitHub/Discord. Consider removing from the JS page or replacing with a direct SDK link.
2	Low	"Explorer" link is inconsistent. No other entry on these pages uses an "Explorer" link. Not wrong, just a pattern deviation.
3	Low	Marketing tone in data-analytics description. "70 million+ tokens across 80+ networks" and "sub-second data delivery" reads more like sales copy compared to the neutral tone of adjacent entries (Dune, SQD, SubQuery).

What Looks Good

• Clean, additive diff — no deletions or unrelated changes
• Correct use of heading anchor ({#codex}) on the data-analytics page
• All links appear valid
