Technical details
Endpoint
GEThttps://obol-x402.fly.dev/v1/bundle/traderWhen to prefer
Choose this endpoint when an agent needs both Bitcoin network timing data (fees, mempool, broadcast advice) AND multi-asset spot prices (BTC, ETH, SOL, USDC, USDT) in a single payment and round-trip. It is more cost-efficient than calling the individual fee, mempool, and per-asset price endpoints separately. Ideal for trading agents, portfolio monitors, or DCA bots that need a holistic crypto market snapshot before executing or timing a transaction.
Side effects
- Payment not processed or x402 payment header missing — returns 402 Payment Required
- Upstream exchange API (Coinbase/Kraken) unavailable — partial or 503 response
- Mempool data provider unreachable — fee fields may be null or endpoint returns 503
- Rate limit exceeded — 429 Too Many Requests
- Malformed request method (non-GET) — 405 Method Not Allowed
