Technical details
Endpoint
GEThttps://palmyr.ai/phone/numbers/test/messages?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically read incoming SMS messages on a Palmyr-managed phone number, especially in agentic workflows where an AI needs to monitor texts, capture verification codes, or process replies. Prefer this over general SMS APIs when already using Palmyr's x402 crypto-payment infrastructure or when operating with a Palmyr-provisioned number.
Side effects
- Phone number not found or not owned/shared — returns 404 or access denied error
- Authentication failure — invalid or missing credentials returns 401
- No messages received — returns empty list
- Rate limiting or quota exceeded — returns 429
- Payment failure via x402 — call rejected if USDC payment is not processed
