HOGSWAP swap quote across every Algorand DEX. Give amount (exact input) OR amount_out (exact output — minimum input is solved). Base units (µ); asset 0 = ALGO. Returns expected_out, route legs, and a quote_id for build_swap. expected_out is NET of the 5 bps routing fee; passing sender also returns router_fee_* fields and the wallet's HOG discount (hog_discount_pct, 100 = fully waived at 100 HOG). Optional sender enables HOG-holding fee discounts. Optional max_legs (1-16) caps TOTAL route legs, splits included — slightly worse price at size, 404 if nothing fits; forward (amount) quotes only.

Unsigned transaction group for a get_quote quote_id. Sign every txn with your own wallet and submit as one group. NEVER pass mnemonics or private keys to any tool — signing happens in YOUR wallet, never here.

Pay ANY Algorand-settled x402 invoice with any 1-4 routable assets you hold, even holding none of the demanded asset. Pass the `accepts` entry you picked as `invoice` (keep its note!) plus your inputs (single input with no amount = minimum solved). Returns UNSIGNED groups — sign all in one pass, submit IN ORDER (swap first; its on-chain floor guarantees the payment is funded; holding the asset already = one direct payment). HOGSWAP credit top-up offers feed this verbatim. EVM invoices unsupported (no bridge). NEVER pass mnemonics or private keys to any tool — signing happens in YOUR wallet, never here.

Self-service HOGSWAP API key, step 1 of 2 — zero human. Returns a challenge; sign its exact bytes with the address's key in YOUR wallet tooling, then call verify_registration. NEVER pass mnemonics or private keys to any tool — signing happens in YOUR wallet, never here.

Self-service key issuance, step 2 of 2. Returns your hsk_ key ONCE — store it yourself; it is not recoverable and this server does not keep it. Send it on later calls as Authorization: Bearer, X-API-Key, or the api_key argument.

Create a credit top-up and get the x402 offer (HTTP 402 IS the payment instruction, not an error). Feed accepts[0] straight into pay_x402_invoice (keep the note nonce) to pay with any asset. Credits land ~1 block after payment.

Value a liquidity-provider position. Give the LP token's asset id (free, no key) and optionally `amount` in LP BASE units — what the wallet holds — for its USD value and the redeemable amount of each underlying. Also identifies the issuing pool/DEX (and STAMM tier). Per-unit figures are per WHOLE LP token. Values are a proportional-share redemption at analytics prices: no slippage, no exit fee, NOT a market quote — fields are null rather than guessed when supply or a price is missing, so check before reporting a number.

Register a standing server-side watch (FREE, needs a key; idempotent upsert by client_key — re-registering replaces the watch and resets arming). kind='price': advisory µUSD threshold (asset_id, op gte/lte, threshold_usd_micro). kind='target': size-aware surrogate — would swapping amount_in of asset_in→asset_out deliver ≥ min_out? (margin_bps haircut, default 30; NO quote is run). Edge-triggered one-shot; re-arms after rearm_bps retreat + cooldown_s; ttl_s auto-expiry (default 86400) — refresh by re-upserting. Fires are numbers-only HINTS: re-quote with get_quote. Events push over SSE at GET /watches/stream (outside MCP); from MCP, poll list_watches.
