Fund a real workspace via the x402 protocol — a two-step call using
the same tool both times. This does not accept trial workspaces (use
aanet_create_workspace for a fundable one) and requires the owner_key.
Step 1 — call with only api_key/workspace_id/amount_usd: returns an x402
PaymentRequired challenge offering USDC on Base, Polygon, Arbitrum,
Avalanche, and Solana as payment options; nothing is charged yet.
Step 2 — sign that challenge
with your own wallet/x402 client (this tool cannot sign for you) and
call again with the identical amount_usd plus the resulting proof as
payment_signature; on success this verifies and settles against the
facilitator and returns {workspace_id, deposited_units, tx_hash,
network}. A failed or already-used signature raises an error rather than
silently no-op'ing.
