Boring DEV, Agentic, and x402 Stuff besides the new HOGSWAP Router fee upgrade. Read at your own peril... HOGSWAP API — what shipped this week: Zero Fees: • Every swap routed through the HOGSWAP API, SDKs, and MCP server pays a 5 bps router fee — and the HOG discount is now perfectly proportional on-chain. The old staircase tiers, where only whole HOG counted, are gone: every µHOG (0.000001 HOG) counts. • 100 HOG in your signing wallet = zero router fee. 50 HOG = half fee. Linear all the way down. • Pass your address with a quote and it prices your discount, so what you're quoted is what you get. Built for AI Agents: • MCP server — 11 tools over npx or remote HTTP. Drop it into Claude and an agent can quote, build, watch, and pay entirely on its own. • pay_x402_invoice — pay any Algorand-settled x402 invoice, from any merchant or API, not just ours. Your agent hits a 402 anywhere on Algorand, feeds it straight in, and settles it with whatever 1-4 assets it actually holds — an exact-out router swap sources the asset it doesn't. • Zero-human onboarding — sign a challenge with your address, get an API key. No email, no form, no waiting. • Strictly non-custodial — every tool returns unsigned transactions. Your wallet signs, always. Nothing ever asks for a key. Standing Watches — Stop Polling: • Register a condition once; the server checks every block and pushes you the moment it arms. • Target watches are size-aware, not naive spot — "would swapping 5,000 USDC into ALGO actually deliver at least X?", with your own impact haircut applied before it fires. • Price watches — a USD threshold on any asset, above or below. • Edge-triggered and one-shot: fires once, then re-arms only after the market retreats by your margin and your cooldown elapses. No alert spam. • One connection per key, sequence-numbered with replay on reconnect — at-least-once delivery, nothing silently dropped. • Idempotent upserts under your own key, TTL auto-expiry, 5,000 standing watches per key. Routing You Control: • max_legs — cap the total number of route legs, parallel pool splits included. Built for vaults and composed groups that replay a router session inside their own transaction budget. • An honest 404 when nothing fits your cap — never a silently worse route. • Exact-output quotes — name the output you need, the minimum input is solved for you. • Missing an opt-in? The build names the exact asset instead of failing opaquely. Start Building: • hogswap-js-sdk (npm) and hogswap-py-sdk (PyPI) — the full surface including watches and zero-dependency SSE readers, sync and async. • Quotes are free and keyless. The whole new surface — watches, advanced routing, the agent tools — is free during beta. Metered pricing comes later with notice, and you'll be able to pay in any asset you hold. The public trading bots will be the first thing running on all of this. So not only are we providing the services, but we are actively using them for the trading bots coming tomorrow or the day after in beta, as well as on our front-end app.liquihog.com #Algorand #AlgoFam #Algorandx402
