/prices works (auto waterfall)
Default — no query params — runs modus=auto.
Response always includes modus: auto; via shows which step served the request.
CF edge cache: 1s on default responses.
Explicit modus=auto bypasses edge cache (no-store).
fly-ccxt / fly-r2
Return cached snapshot if Fly wrote it ≤10s ago. Fast path — no exchange API from CF.
direct-rest
Worker calls exchange REST (spot + swap: binance, bybit, okx, myokx, bitget, mexc; kraken swap only). Binance/bitget 403 from CF edge → proxy-scraper fallback.
worker-ccxt
Lazy-load ccxt in the Worker and fetchTickers (5s timeout). Spot + swap.
fly-ccxt / fly-r2
Accept Fly snapshot if ≤60s old — better than nothing while Fly catches up.
fly-live
CF calls Fly /prices?live=true (up to 90s). Response includes r2LastFetchSecondsAgo when R2 exists.
Overrides:
modus=direct / modus=worker — force one path, then Fly live fallback.
live=true — skip waterfall, Fly live only.
R2 snapshots with modus !== fly are skipped (edge pollution guard).
Examples:
/prices?exchange=bybit&defaultType=swap (default auto) ·
&modus=direct ·
&check=true (metadata only).

Search cached R2 prices across exchanges — try BTC, ETH, or QQQ.
Enter a symbol (e.g. BTC, ETH, QQQ) and press Search.
/prices works (auto waterfall)
Default — no query params — runs modus=auto.
Response always includes modus: auto; via shows which step served the request.
CF edge cache: 1s on default responses.
Explicit modus=auto bypasses edge cache (no-store).
fly-ccxt / fly-r2
Return cached snapshot if Fly wrote it ≤10s ago. Fast path — no exchange API from CF.
direct-rest
Worker calls exchange REST (spot + swap: binance, bybit, okx, myokx, bitget, mexc; kraken swap only). Binance/bitget 403 from CF edge → proxy-scraper fallback.
worker-ccxt
Lazy-load ccxt in the Worker and fetchTickers (5s timeout). Spot + swap.
fly-ccxt / fly-r2
Accept Fly snapshot if ≤60s old — better than nothing while Fly catches up.
fly-live
CF calls Fly /prices?live=true (up to 90s). Response includes r2LastFetchSecondsAgo when R2 exists.
Overrides:
modus=direct / modus=worker — force one path, then Fly live fallback.
live=true — skip waterfall, Fly live only.
R2 snapshots with modus !== fly are skipped (edge pollution guard).
Examples:
/prices?exchange=bybit&defaultType=swap (default auto) ·
&modus=direct ·
&check=true (metadata only).
Status table below tracks Fly R2 freshness (≤10s = ok for step 1).
API requests use a logical exchange name (exchange= param) for R2 cache keys and active-pair tracking.
Fly may use a different ccxt backend to fetch prices.
Example log: CcxtConnector loaded: binance spot (logical: zigdao).
| Logical | ccxt backend | Applies to | Mapping | Notes | R2 key example |
|---|---|---|---|---|---|
| kraken | krakenfutures | swap only | alias | Kraken futures/perps (swap only) | prices_kraken_swap |
| myokx | myokx | spot & swap | direct | OKX EEA (EU) — ccxt myokx, hostname eea.okx.com | prices_myokx_swap |
| woo | woo | spot & swap | direct | WOO X — own ccxt exchange (not an alias) | prices_woo_spot |
| zigdao | binance | spot & swap | alias | Zignaly — Binance prices, cached under zigdao | prices_zigdao_spot |
Other exchanges (binance, bybit, mexc, …) use the same name for logical and ccxt. R2 keys always use the logical name.
