check_networkchangeddescription

Answers whether one plan's network directory lists one provider. answer "listed" (in_network: true) comes with evidence: plan year, network tier and source {type, as_of}. answer "not_found" (in_network: null) means no listing was found in current directory data for this provider and plan; it is NOT a statement that the provider is out of network, so never report it as "out of network". answer "no_provider_network" is a drug-only plan. Directories change; tell users to confirm with the plan before care. Costs 1 call.

When a directory listing also exists, the answer is "listed" and the contracted item follows it in evidence. answer "no_provider_network" is a drug-only plan.

plans_for_providerchangeddescription
before
Every Marketplace (ACA) and Medicare Advantage plan whose network directory lists the provider, one row per plan and plan year, each with plan name, insurer, state, network tier and source {type, as_of}. Medicare Advantage rows carry service_area_states and provider_state_in_service_area. Filter by market, state or year; page with limit and offset (next_offset is null on the last page). A plan missing from this list is not a statement that the provider is out of network. Costs 1 call per page.

Every Marketplace (ACA) and Medicare Advantage plan whose network directory lists the provider, one row per plan and plan year, each with plan name, insurer, state, network tier, evidence_tier (the row's answer, highest tier first), source {type, as_of} and evidence (every proof we hold for that plan, in tier order). Rows with evidence_tier 'named_network' are plans whose own name identifies their network, where the insurer's directory lists the provider in that network (network_name); report them as 'listed in the network this plan names', never as 'listed'. Rows with evidence_tier 'contracted_network' are plans where the insurer's published contract files list this provider in the network for the plan's product (network_labels); report them as 'contracted network', never as 'listed'. Medicare Advantage rows carry service_area_states and provider_state_in_service_area. Filter by market, state or year; page with limit and offset (next_offset is null on the last page). A plan missing from this list is not a statement that the provider is out of network. Costs 1 call per page.

plans_for_providerread-only
Every Marketplace (ACA) and Medicare Advantage plan whose network directory lists the provider, one row per plan and plan year, each with plan name, insurer, state, network tier, evidence_tier (the row's answer, highest tier first), source {type, as_of} and evidence (every proof we hold for that plan, in tier order). Rows with evidence_tier 'named_network' are plans whose own name identifies their network, where the insurer's directory lists the provider in that network (network_name); report them as 'listed in the network this plan names', never as 'listed'. Rows with evidence_tier 'contracted_network' are plans where the insurer's published contract files list this provider in the network for the plan's product (network_labels); report them as 'contracted network', never as 'listed'.

search_plan_providersread-only
Providers that a Marketplace (ACA) plan's network directory lists, with name, credential, primary specialty, network tiers and up to 5 locations. Filter by state, specialty (substring, e.g. "cardiology"), zip, or zip plus radius in miles. Pages are cursor-based: pass next_cursor back unchanged until it is null; with filters a page can hold fewer than limit providers. Medicare Advantage plans: use check_network or plans_for_provider instead. Needs the Growth plan or higher. Costs 1 call per page.
