## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability obol-trader-bundle-bitcoin-fees-multi-asset-spot-prices-1c576e5a
```

Example prompt: Pull the full trader bundle for me — I need Bitcoin's current mempool congestion, next-block fee estimate, and broadcast advice, plus spot prices for BTC, ETH, SOL, USDC, and USDT with any cross-exchange divergence flags, all in one shot.

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Trader bundle: full Bitcoin pulse (fees mempool congestion) PLUS multi-asset USD spot prices BTC ETH SOL USDC USDT with divergence — one payment for research and timing agents. Cryptographically signed (Ed25519) — every response is independently verifiable via /.well-known/obol-pubkey.

## Output

A unified JSON payload containing: Bitcoin next-block fee in sat/vB, mempool congestion tier, fee-spike flag, ok_to_broadcast/wait_or_pay_up advice, and USD spot prices for BTC, ETH, SOL, USDC, and USDT sourced from Coinbase and Kraken with a divergence flag indicating when prices differ significantly across exchanges.
