Outils

9 outils
account
Your balance, totals, limits, and recent calls. Requires Authorization: Bearer <gwk_ key>.
Schéma d’entrée 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
call_service
Call a catalog service through the gateway. The gateway pays the upstream x402 USDC price from its own wallet and deducts your prepaid credits (upstream price + 25% markup, min $0.005). Requires an account key with credits.
Schéma d’entrée 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['id'], 'properties': {'id': {'type': 'string'}, 'body': {'description': 'JSON body for POST services'}, 'query': {'type': 'object', 'description': 'URL query params', 'additionalProperties': {}}}, 'additionalProperties': False}
create_account
Create a gateway account. Returns your secret key (gwk_…) - store it; it is shown only once. New accounts start at 0 credits.
Schéma d’entrée 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
create_owner_key
One-time: mint a separate OWNER key (gwo_…) for the human supervisor. After this, the gwk_ agent key can spend and TIGHTEN limits but never loosen or clear them; only the owner key can. Shown once - the human should store it where the agent can't read it. Requires Authorization: Bearer <gwk_ key>.
Schéma d’entrée 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
create_topup_link
Create a hosted card-payment link (Stripe Checkout) that adds $5, $10 or $20 of credits to YOUR account. Give the returned url to your human to open and pay - no crypto wallet needed; credits land 1:1 within seconds of payment. Requires Authorization: Bearer <gwk_ key>.
Schéma d’entrée 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['pack'], 'properties': {'pack': {'type': 'number', 'description': 'USD amount: 5, 10 or 20'}}, 'additionalProperties': False}

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['id'], 'properties': {'id': {'type': 'string'}}, 'additionalProperties': False}
list_services
Search the graded catalog of x402 services (ours + the Bazaar), ranked by real 30-day demand and agent-usability grade (A-F). Free.
Schéma d’entrée 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'grade': {'type': 'string', 'description': 'comma list of grades, e.g. "A,B"'}, 'limit': {'type': 'number', 'description': 'max 100 per page'}, 'query': {'type': 'string', 'description': 'substring match on name/description'}, 'offset': {'type': 'number', 'description': 'pagination offset'}, 'callable': {'type': 'boolean', 'description': 'only services callable through the gateway'}}, 'additionalProperties': False}
set_limits
Configure YOUR account's spending guardrails, enforced on every call_service: max_call_usd (refuse any call charging more), daily_usd (rolling-24h charge budget), min_grade (refuse services graded below it), allow (exact service-id allowlist). Send only fields to change; null clears a field. Requires Authorization: Bearer <gwk_ key>.
Schéma d’entrée 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'allow': {'anyOf': [{'type': 'array', 'items': {'type': 'string'}, 'maxItems': 200}, {'type': 'null'}], 'description': 'service-id allowlist; only these are callable'}, 'daily_usd': {'anyOf': [{'type': 'number', 'maximum': 1000, 'exclusiveMinimum': 0}, {'type': 'null'}], 'description': 'max USD charged per rolling 24h'}, 'min_grade': {'anyOf': [{'enum': ['A', 'B', 'C', 'D'], 'type': 'string'}, {'type': 'null'}], 'description': 'refuse services graded below this'}, 'max_call_usd': {'anyOf': [{'type': 'number', 'maximum': 100, 'exclusiveMinimum': 0}, {'type': 'null'}], 'description': 'max USD charged per call'}}, 'additionalProperties': False}
