POST /api/v1/credits/coinbase deprecated

Coinbase deprecated the APIs used by this flow, so `POST /api/v1/credits/coinbase` has been removed and now returns `410 Gone`. Status The old programmatic Coinbase Commerce charge flow is no longer supported because Coinbase deprecated the underlying APIs it relied on. This includes the legacy flow that returned on-chain calldata for direct settlement. What To Use Instead Use the web credits purchase flow on your [credits page](https://openrouter.ai/settings/credits). OpenRouter now uses Coinbase Business Checkouts for active Coinbase credit purchases. Affected Endpoint POST /api/v1/credits/coinbase Current behavior: { "error": { "code": 410, "message": "The Coinbase APIs used by this endpoint have been deprecated, so the Coinbase Commerce credits API has been removed. Use the web credits purchase flow instead." } }
