AgentKit on npm is 0.10.4 from December 2025, and its fix for a local file read and public upload path is unreleased. **Sponge Wallet.** An agent can register a wallet with one unauthenticated call and pay x402 or MPP endpoints under daily, weekly and monthly limits enforced on Sponge's servers. No status page, rate limits, fee schedule, custody statement or security contact was found, the terms run to eleven short clauses, and the SDK was last published on 7 July 2026. ## Before you call either ### Coinbase Developer Platform (Agentic Wallet, AgentKit, CDP MCP) 1. Run `npx awal@2.12.1 status` first and sign in with `auth login` and `auth verify` if it fails 2. Pass `--max-amount` on every `awal x402 pay`; 1000000 is $1.00 3. Send an `X-Idempotency-Key` on server-wallet writes so a retry can't send twice 4. Don't register AgentKit's flaunch or zora providers on 0.10.4; they read local files 5. Give an agent a policy-bound server account or an Agentic Wallet, never a full CDP API key ### Sponge Wallet 1. Send `Sponge-Version` on every REST request. The skill file marks it required and the API answers with version status headers 2. Use `evmTransfer` and `solanaTransfer`, the helpers the docs describe as enforcing allowlists and spending limits, not plain `transfer` 3. Store the `apiKey` from registration at once. It is returned a single time, and losing it means registering again 4. Call `GET /api/discover/{serviceId}` before `POST /api/paid/fetch`. The skill file says direct service URLs fail with auth errors 5. Treat `card details` output as secret. It returns an encrypted card number and CVC with a one-time `secret_key` ## Questions ### Which is better for AI agents, Coinbase Developer Platform (Agentic Wallet, AgentKit, CDP MCP) or Sponge Wallet?
