API

Every number on this site is served as JSON from the same routes, with no key.

Routes

Route	Returns
`GET /api/pools`	the universe: every pool, its gates, weight, and 30-epoch fee and volume series
`GET /api/eigen`	λ, explained variance, λ₁ loadings, factor scores, the correlation matrix
`GET /api/nav`	NAV series, per-epoch harvest, trailing APR
`GET /api/stats`	protocol summary: streams, TVL, λ₁ share, epoch
`GET /api/epochs`	current epoch and seconds to the next harvest window
`GET /api/chain`	live block number and gas price from the RPC
`GET /api/contracts`	the address registry this site is built against
`GET /api/card/epoch`	a 1080×1080 share card, rendered live

Data sources

Pool discovery, 24-hour volume, liquidity and thirty days of daily volume come from GeckoTerminal on the robinhood network. That free tier rate-limits bursts, so reads are paced, retried with backoff, memoised for twenty minutes and warmed by a cron job every ten. Chain reads go straight to the RPC with batching disabled, because this node answers JSON-RPC batches in an order viem cannot line back up.

If GeckoTerminal is unreachable the whole site falls back to a deterministic day-seeded model in lib/sim.ts and every affected panel is labelled model. The fallback exists so a rate limit degrades the numbers rather than the page.
