# x402-funding.onrender.com /ultra — Funding Divergence Execution Capacity

> x402-funding.onrender.com /ultra — Funding Divergence Execution Capacity is a paid API for AI agents from x402-funding.onrender.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-11-02).

Returns the maximum notional executable on both legs of a funding divergence pair before combined market impact exceeds a given bps budget, plus book depth and carry needed to recover entry cost

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 x402-funding-onrender-com-ultra-funding-divergence-execution-capacity-1e04c896
```

Example prompt: Show me the top 5 funding divergence pairs with the largest simultaneously executable notional within a 15 bps market impact budget, including book depth and the carry needed to cover entry costs.

## When to prefer this

Use this endpoint when you need quantitative, market-microstructure-level analysis of how much capital can actually be deployed in a funding rate arb before market impact eats the trade. It is distinct from endpoints that merely report funding rate spreads — this one translates those spreads into executable size, book depth, and break-even carry, making it directly useful for pre-trade capacity planning. Prefer it over generic funding rate screeners when execution feasibility and impact cost matter.

## Known failure modes

- limit parameter out of range (1-20) returns validation error
- capacity parameter out of range (1-10) returns validation error
- fees_bps out of range (0-200) returns validation error
- public order book data temporarily unavailable causing degraded or empty results
- rate limiting or payment failure (x402 protocol) if USDC payment not attached

## How this service works

Funding divergence with execution capacity: for each pair, the largest notional executable on both legs at once before their combined market impact exceeds a stated bps budget, the book depth behind that number, and the carry needed to repay the entry cost. Measured from public order books. No recommendation, no position sizing, no investment advice.

## Output

Returns a ranked list of funding divergence pairs with: the maximum notional executable simultaneously on both legs before combined market impact exceeds the stated bps budget, the order book depth backing that figure, and the carry (in bps or annualized rate) required to repay the entry cost. Data is sourced from live public order books with no position recommendations.
