Every rule whose selector covers this component's kind or its category. Whether a rule fires depends on the design: its properties, its edges and its groups.
sync-chain-too-deep
Every consecutive synchronous hop from this entry point spends part of the stated p95 latency budget, and the chain's failures multiply. More than three hops is a budget nobody is tracking.
- — all of these hold:
- — the design requirement `latency.p95Ms` has a value
- — the longest chain of synchronous calls starting at the node is more than 3 hops long

Per "Provider Routing", it routes to # the cheapest provider first and fails over automatically; per "LLM Caching", caching is off until the # Helicone-Cache-Enabled header is sent (max-age 604800); rate limits need the Helicone-RateLimit-Policy header. schemaVersion: "1" type: "component" id: "helicone-gateway" kind: "api-gateway" provider: "default" docs: "https://docs.helicone.ai/gateway/provider-routing" defaults: managed: true auth: "api-key" protocol: "http" tls: true rateLimiting: false properties: routingStrategy: type: "enum" values: ["cheapest-first", "provider-order"] default: "cheapest-first" fallbacks: type: "boolean" default: true caching: type: "boolean" default: false cacheTtlSeconds: type: "integer" default: 604800
