Streaming: stop polling Katana

Open one SSE connection and we push token prices and per-block pool reserve deltas as Katana state changes — the only push-based reserves feed on the market. Poll loops re-fetch unchanged state and still miss mid-block moves; push delivery makes the gap between on-chain state and your app the network round-trip, nothing else.

# push: live vbUSDC price ticks on Katana — one connection, no polling
curl -N "https://streaming.dexpaprika.com/sse/prices?chain=katana&address=0x203a662b0bd271a6ed5a60edfbd04bfce608fd36&method=token_price"

# push: per-block reserve deltas for vbUSDC pools
curl -N "https://streaming.dexpaprika.com/sse/reserves?chain=katana&address=0x203a662b0bd271a6ed5a60edfbd04bfce608fd36&method=token_reserves"

How fresh is the Katana data?

Data updates every Katana block. REST responses reflect the latest indexed block; SSE streams push changes as they happen — there is no polling interval between your app and Katana chain state.

Do I need an API key for Katana data?

No. Every REST endpoint and SSE stream works without a key or signup — 200K requests per month free. Pro ($99/mo) lifts the ceiling to 5M requests.

How do I get a Katana token price with the API?

GET /networks/katana/tokens/{address} returns the live USD price with 24h volume and liquidity in one call. For portfolios, /networks/katana/multi/prices returns batched prices for up to 10 tokens per request.

Does streaming work for Katana?

Yes — SSE streams at streaming.dexpaprika.com push Katana token prices (/sse/prices) and per-block pool reserve deltas (/sse/reserves). It is the only push-based reserves feed on the market.

What does the Katana DEX API cost?

The free tier includes 200K requests per month with no API key or credit card, on every endpoint and every chain. Pro is $99/mo for 5M requests with priority support.
