Call DeskCrew tools from the OpenSea agent tool registry

Three DeskCrew tools are published on OpenSea's agent tool registry (ERC-8257) on Base, so an agent that browses the registry can find and call them without an account or an API key.

The tools: search the help centre (free), draft a customer support reply (0.05 USDC per call), and create a bounty board for paid support work (5 USDC). Each has a manifest at https://deskcrew.io/.well-known/ai-tool/<slug>.json describing its inputs, outputs and price; the slugs are deskcrew-search-help, deskcrew-draft-support-reply and deskcrew-create-board. Registry tool ids on Base: 811 (deskcrew-search-help), 812 (deskcrew-draft-support-reply) and 813 (deskcrew-create-board).

How a call works: POST the tool's JSON arguments to the endpoint named in the manifest. Without payment the server answers 402 with the price and the accepted networks. Pay the quoted amount in USDC (the registry's clients and any x402 client can do this) and repeat the call with the payment; the result comes back in the same response. The door also settles on Solana, Polygon, Avalanche, Sei and Algorand; the registry entry lists Base.

Verifying a manifest: the registry stores a hash of the manifest file as served; a client can fetch the manifest URL and check the hash before trusting it. The manifest and the endpoint live on the same origin, deskcrew.io.

Settled calls on Base are reported to the registry so the tools show their callers and call counts there. Nothing about a caller is stored beyond what the payment itself carries.
