Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| find_serviceA | Search the Obol directory for metered APIs an agent can pay for per call. Results are relevance-ranked (name > category > description). Returns id, price (USDC), description, the callable URL, and a relevance score. |
| depositA | Fund the agent's Gateway balance once (gas-free spending afterward). Amount in USDC, e.g. '5'. |
| pay_and_callA | Pay for and call an Obol metered service via Circle Gateway. Enforces your per-call maxPrice and (with OBOL_API_KEY) your account's daily/weekly/monthly spending limits. Near-limit pays ask you to confirm. Idempotent on retry. Returns the result plus a signed, verifiable payment receipt. |
| list_serviceA | List (publish) a new service on the Obol marketplace so other agents can discover and pay for it. Requires the seller's Obol API key (OBOL_API_KEY env). Obol auto-issues a real ACK-ID verifiable credential for the seller's wallet and returns the marketplace URL. |
| get_balanceA | Get the agent wallet + Gateway USDC balances on Arc testnet. |
