# Seerium DEX Orderbook Pressure Feed

> Seerium DEX Orderbook Pressure Feed is a paid API for AI agents from api.seerium.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Returns real-time DEX order book pressure metrics including bid/ask depth imbalance, buy/sell-side pressure, microprice bias, spread in bps, notional liquidity, funding, and confidence for crypto symbols.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 seerium-dex-orderbook-pressure-feed-43e1c355
```

Example prompt: Show me the order book pressure for BTC-PERP on DEX — give me up to 20 results using 10 book levels, only show markets with a spread under 5 bps and at least $100,000 in combined notional depth, and include the bid/ask imbalance, microprice bias, and confidence score.

## When to prefer this

Use this endpoint when an AI agent needs real-time DEX order book microstructure signals — specifically bid/ask pressure imbalance, microprice bias, spread quality, and notional depth — for crypto symbols including perpetuals. Prefer this over generic price feeds when market-making conditions, entry timing, or liquidity screening are the goal.

## Known failure modes

- No symbols match the provided symbol filter — returns empty results
- minTotalDepthNotional too high — filters out all markets
- maxSpreadBps too tight — no markets pass the filter
- limit or levels parameter out of valid range — validation error
- Symbol string unrecognized or malformed — no data returned
- Service unavailable or rate limit hit — HTTP 402 or 5xx error

## How this service works

Crypto and prediction market intelligence through x402.

## Output

Returns a ranked list of active DEX symbols with bid/ask depth imbalance ratio, buy-side and sell-side pressure scores, microprice bias, top-of-book spread in basis points, combined notional liquidity, funding rate, and a confidence score for each symbol — filtered and limited per query parameters.
