}Provider Routing
Control which provider handles your request using the X-0G-Provider-* request headers.
X-0G-Provider-Address pins a provider; X-0G-Provider-Identity pins which of its upstreams to route through — both values come from the address and provider_identity fields of GET /v1/providers. Together they address one specific upstream of one provider. Send neither and the router picks by price and health, exactly as before.
