Tools
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.
Eingabeschema
{'type': 'object', 'title': 'build_swapArguments', 'required': ['quote_id', 'user_address'], 'properties': {'api_key': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Api Key', 'default': None}, 'quote_id': {'type': 'string', 'title': 'Quote Id'}, 'user_address': {'type': 'string', 'title': 'User Address'}}}

delete_watch
Delete one of your watches by its client_key.

get_balance
Current HOGSWAP credit balance for your API key.

{'type': 'object', 'title': 'get_balanceOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
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.
Eingabeschema
{'type': 'object', 'title': 'get_credit_offerArguments', 'required': ['usdc_micro'], 'properties': {'api_key': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Api Key', 'default': None}, 'usdc_micro': {'type': 'integer', 'title': 'Usdc Micro'}}}
Ausgabeschema
{'type': 'object', 'title': 'get_credit_offerOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
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 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.
Eingabeschema
{'type': 'object', 'title': 'get_quoteArguments', 'required': ['asset_in', 'asset_out'], 'properties': {'amount': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Amount', 'default': None}, 'sender': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Sender', 'default': None}, 'api_key': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Api Key', 'default': None}, 'asset_in': {'type': 'integer', 'title': 'Asset In'}, 'max_legs': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Max Legs', 'default': None}, 'asset_out': {'type': 'integer', 'title': 'Asset Out'}, 'amount_out': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Amount Out', 'default': None}}}
Ausgabeschema
{'type': 'object', 'title': 'get_quoteOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
list_payable_assets
Assets accepted as payment inputs for pay_x402_invoice and credit top-ups (price-confidence gated; ALGO and USDC always included).
Eingabeschema
{'type': 'object', 'title': 'list_payable_assetsArguments', 'properties': {}}
Ausgabeschema
{'type': 'object', 'title': 'list_payable_assetsOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
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.
Eingabeschema
{'type': 'object', 'title': 'list_watchesArguments', 'properties': {'api_key': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Api Key', 'default': None}}}

{'type': 'object', 'title': 'list_watchesOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
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 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.
Eingabeschema
{'type': 'object', 'title': 'pay_x402_invoiceArguments', 'required': ['invoice', 'user_address', 'inputs'], 'properties': {'inputs': {'type': 'array', 'items': {'type': 'object', 'additionalProperties': True}, 'title': 'Inputs'}, 'api_key': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Api Key', 'default': None}, 'invoice': {'type': 'object', 'title': 'Invoice', 'additionalProperties': True}, 'user_address': {'type': 'string', 'title': 'User Address'}}}
Ausgabeschema
{'type': 'object', 'title': 'pay_x402_invoiceOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
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.
Eingabeschema
{'type': 'object', 'title': 'register_agentArguments', 'required': ['address'], 'properties': {'address': {'type': 'string', 'title': 'Address'}}}
Ausgabeschema
{'type': 'object', 'title': 'register_agentOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
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 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.
Eingabeschema
{'type': 'object', 'title': 'set_watchArguments', 'required': ['client_key', 'kind'], 'properties': {'op': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Op', 'default': None}, 'kind': {'type': 'string', 'title': 'Kind'}, 'ttl_s': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Ttl S', 'default': None}, 'api_key': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Api Key', 'default': None}, 'min_out': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Min Out', 'default': None}, 'asset_id': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Asset Id', 'default': None}, 'asset_in': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Asset In', 'default': None}, 'amount_in': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Amount In', 'default': None}, 'asset_out': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Asset Out', 'default': None}, 'rearm_bps': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Rearm Bps', 'default': None}, 'client_key': {'type': 'string', 'title': 'Client Key'}, 'cooldown_s': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Cooldown S', 'default': None}, 'margin_bps': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Margin Bps', 'default': None}, 'threshold_usd_micro': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Threshold Usd Micro', 'default': None}}}
Ausgabeschema
{'type': 'object', 'title': 'set_watchOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
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 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.
Eingabeschema
{'type': 'object', 'title': 'value_lp_tokenArguments', 'required': ['asset_id'], 'properties': {'amount': {'anyOf': [{'type': 'integer'}, {'type': 'null'}], 'title': 'Amount', 'default': None}, 'asset_id': {'type': 'integer', 'title': 'Asset Id'}}}
Ausgabeschema
{'type': 'object', 'title': 'value_lp_tokenOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
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.
Eingabeschema
{'type': 'object', 'title': 'verify_registrationArguments', 'required': ['address', 'challenge', 'signature_b64'], 'properties': {'address': {'type': 'string', 'title': 'Address'}, 'challenge': {'type': 'string', 'title': 'Challenge'}, 'signature_b64': {'type': 'string', 'title': 'Signature B64'}}}
