Technical details

Endpoint

POSThttps://flipr-x402.fly.dev/x402/opportunity/subscribe

When to prefer

Use this endpoint when an agent needs to be proactively notified about new opportunities on Flipr.bet without polling repeatedly. Prefer this over polling-based approaches when low-latency reaction to opportunities is important and the agent has a stable callback URL to receive webhooks.

Side effects

Invalid or unreachable callback URL — subscription creation fails
Payment failure (insufficient USDC) — 402 response, subscription not created
Duplicate subscription for same callback URL — may return conflict or duplicate resource
Malformed request body — 400 Bad Request
Rate limiting or quota exceeded — 429 Too Many Requests
