Find, price, rent and stop GPUs on AmpleRun. Paid in USDC or USDT on Base. Flat 5% fee.
Scored across 2 tools
The two tools form an explicit, ordered flow (Step 1 of 2, Step 2 of 2) with no overlap: one issues an EIP-4361 challenge, the other consumes its message+signature to create the account. An agent cannot reasonably confuse which to call at a given step.
Both names use snake_case with a leading verb (get_..., register_...), making the pattern predictable. The only minor wrinkle is that 'get_agent_account_challenge' is a longer noun stack than the bare 'register_agent_account', but the convention holds.
Two tools is thin for a server branded as a GPU rental marketplace, even if this slice is intentionally the auth gateway. The pair is coherent and each earns its place, but the surface is borderline minimal for the apparent scope.
Only account onboarding exists; there are no tools to search GPUs, fund a deposit, rent, manage rentals, or act as a host, despite descriptions referencing deposits and renter/host scopes. An agent can register but then hits a dead end for the server's stated purpose.
Step 1 of 2. Returns an EIP-4361 (Sign-In with Ethereum) message for a wallet address this agent controls, valid five minutes, single use. Signing it accepts the AmpleRun Terms version it names. Sign the message exactly as returned with personal_sign (EIP-191), then call register_agent_account with message and signature. Never send a private key to any tool.
Inputs: address.
Step 2 of 2. Opens an AmpleRun account for this AI agent, tagged as agent-created, with its wallet as the verified payout wallet, and returns an API key (shown once; keep it secret). The same wallet again returns the same account and a new key. There is no free credit: renting needs a deposit first. Pass message and signature from get_agent_account_challenge. scopes defaults to ["renter","host"].
Inputs: agent (required), scopes, message, signature.
