Returns the top podcast advertising sponsors ranked by the specified metric, with optional time range and company filtering. All-time rankings — and two day-anchored windows: the trailing 7 days (since = UTC today−7d, no until) and the 7-day window ending 30 days ago (since = today−37d, until = today−30d) — reflect periodically refreshed snapshots; other time-windowed and company-filtered results may be cached for up to one hour.

## Other responses

- `402`: Payment Required. Read error_code. payment_required is the x402 path: either a keyless request being challenged — pay $0.04 in USDC per request (requirements in the PAYMENT-REQUIRED header) or send a pp_ API key — or a supplied payment that failed settlement (details in the PAYMENT-RESPONSE header; retry the same signature before signing a new one). See https://docs.particle.pro/x402. Any other code means the credential was accepted but does not cover this request (a plan or session gate such as premium_required or paid_plan_confirmation_required); its resolve says how to obtain access, and no payment header is sent.
- `default`: Error
