Example use cases

Technical details
Endpoint
GEThttps://rentcast.x402.paysponge.com/avm/rent/long-termWhen to prefer
Use this endpoint when you need an automated, data-driven estimate of how much a residential property can rent for on a long-term basis. Prefer this over sale/value endpoints when the goal is rental income analysis, landlord pricing decisions, or investment yield calculations. Choose this over market statistics endpoints when you need a per-property estimate rather than aggregate area trends.
Side effects
- Address not found or unrecognizable — returns 404 or empty result
- Insufficient comparable data in the area — returns low confidence or null estimate
- Missing required query parameters such as address — returns 400 bad request
- Payment not completed via x402 — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
