Add 402s.shop to ecosystem (Services/Endpoints)

[402shop]

Description

Adds 402s.shop to the ecosystem (Services/Endpoints).

402s.shop is a pay-per-call HTTP 402 utility API for AI agents:

• 12 endpoints mirrored under /api/x402/<name> on Base mainnet (real USDC)
• Default 0.001 USDC per call (LLM endpoints 0.01)
• Verify + settle via the Coinbase facilitator (https://x402.org/facilitator)
• Server holds no private keys — settlement direct to merchant wallet
• Machine-readable manifest: https://402s.shop/api/v1
• Also published as an MCP server: https://smithery.ai/server/ucebuceb/shop402

Merchant payTo: 0xF17753bC761Cf248b43Bed57d433254C6BDB5De7

Tests

Ecosystem listing only — metadata + logo, no code changes. The underlying x402
endpoint was verified end-to-end on Base Sepolia (testnet) via the Coinbase
facilitator with a full sign → verify → settle round-trip; mainnet deployed
with the same code path. Probe any /api/x402/<name> endpoint without a
payment header to see the spec-compliant 402 response.

Checklist

• I have formatted and linted my code
• All new and existing tests pass
• My commits are signed (required for merge) -- you may need to rebase if
  you initially pushed unsigned commits
• I added a changelog fragment for user-facing changes (docs-only changes
  can skip)

[vercel]

@402shop is attempting to deploy a commit to the Coinbase Team on Vercel.

A member of the Team first needs to authorize it.

Friendly bump on this — happy to address any review feedback when someone has
cycles.

Quick context for whoever picks this up: the "unstable" CI signal is from
Vercel preview deploy needing Coinbase team auth for the fork (vercel[bot]
comment above). The content change itself is a 12-line additive entry under
services/endpoints — no library or framework code touched.

Since the Saturday push, the entry now reflects 16 endpoints (added a
4-endpoint crypto cluster: wallet_balance, ens_resolve, coin_price,
gas_price). Happy to update the PR to match if helpful — let me know.

End-to-end x402 mainnet settlement was verified last weekend (BaseScan tx
0x7d216cf4...). Standing by for review.
