Setup, endpoints, troubleshooting by exact error string, and billing. If an error message brought you here, go straight to the gateway error reference and search the verbatim string.
Getting started
Change one base_url and your agent is routing. These pages cover the whole first run.
- Setup guideCreate a key, point your agent at the gateway, send a first call.
- OpenClaw setupThe one-line change in openclaw.json, and what routing does to an agent making hundreds of calls a day.
- How routing decidesTask classification, capability filtering, cost ordering and failover — the four steps behind every call.
- Cost calculatorEstimate a monthly bill before switching, priced from the same registry the gateway routes on.
Troubleshooting
Errors are indexed by their exact string, because that is how you search when an agent breaks in production. Paste the verbatim message, including HTTP status.
- Gateway error referenceThe full index: exact error string, what it means, and the fix. Start here.
- Unsupported parameter: max_tokensNewer OpenAI models reject the parameter older SDKs still send.
- SSE stream connection reset mid-responseWhy long streams drop, and which layer actually cut them.
- Embedding dimension mismatchWhat happens when an index and a model disagree on vector width.
- JSON mode returned invalid JSONWhy structured output fails and what to constrain instead.
Models, routing and pricing
