12 tools

• list_payable_assets

  Assets accepted as payment inputs for pay_x402_invoice and credit top-ups (price-confidence gated; ALGO and USDC always included).

• get_quote

  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…

• build_swap

  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_x402_invoice

  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…

• register_agent

  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.

• verify_registration

  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.

• get_credit_offer

  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.

• get_balance

  Current HOGSWAP credit balance for your API key.

• value_lp_token

  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…

• set_watch

  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…

• list_watches

  List your key's active watches (spec + arming/fired state), quota, and latest event seq. Poll this from MCP to see fires; SSE at GET /watches/stream is the push alternative outside MCP.

• delete_watch

  Delete one of your watches by its client_key.
