A person must sign up by email and create a passkey before an agent can pay. No published fee rate, OpenAPI file or Passport status page was found.\n\n**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.\n\n## Before you call either\n\n### Kite Agent Passport\n\n1. Run `kpass` with `--output json --no-interactive` and branch on the exit code and `error_code`. Exit 6 is a session policy breach, so request a new session rather than logging in again\n2. Pass `--idempotency-key` on every `kpass session execute` so a retry after a timeout does not pay twice\n3. Ask the person for a session with a small per-transaction cap and a short `--ttl`, and confirm the merchant URL before executing\n4. Use `kpass sandbox` test mode and the faucet to try a payment flow without real funds. Scoped cards are not available in sandbox\n5. Check the kite-passport skill's trigger rules before installing it, since it directs the agent to paid services ahead of free tools\n\n### Sponge Wallet\n\n1. Send `Sponge-Version` on every REST request. The skill file marks it required and the API answers with version status headers\n2. Use `evmTransfer` and `solanaTransfer`, the helpers the docs describe as enforcing allowlists and spending limits, not plain `transfer`\n3. Store the `apiKey` from registration at once. It is returned a single time, and losing it means registering again\n4. Call `GET /api/discover/{serviceId}` before `POST /api/paid/fetch`. The skill file says direct service URLs fail with auth errors\n5. Treat `card details` output as secret. It returns an encrypted card number and CVC with a one-time `secret_key`\n\n## Questions\n\n### Which is better for AI agents, Kite Agent Passport or Sponge Wallet?\n\nKite Agent Passport scores 51.5 (D) on agent readiness against Sponge Wallet's 43.2 (E), and leads in 5 of 7 scored categories.
