Filter by static eligibility for x402 payment (POST /x402/v1/run): true keeps only payable endpoints, false only non-payable ones. Omit for all endpoints.

Narrow to endpoints payable via x402 on this customer-payment network (CAIP-2 id, e.g. eip155:8453). Implies supportsX402=true; an unknown/unconfigured id returns an empty page.

Filter by whether running the endpoint can change your workspace resources (phone numbers, files, asset libraries): true keeps only endpoints that cannot create, modify or delete them, false only endpoints that can. Omit for all endpoints. This describes RESOURCE effects only — a readonly endpoint may still perform real-world actions and is still billed.

Keep only endpoints whose run can have AT LEAST ONE of the named effects on your workspace resources (phone numbers, files, asset libraries): creates, updates, deletes. Omit for all endpoints. Takes precedence over readonly (readonly=true is the alias for "no write effects"). Resource effects only — an endpoint with no effect may still perform real-world actions and is still billed.

Node id filter. A TOP id returns the top plus its member nodes; a leaf/provider id returns that single node. Omit for every node.

Optional free-text query — counts become per-node search hit counts (same BM25 semantics as GET /public/v1/endpoints?q=). Nodes with zero hits are omitted.
