# Funding Rate Annualize

> Funding Rate Annualize is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Converts a periodic funding rate (e.g. 8-hour) into an annualized APR for cross-venue funding rate comparison.

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 funding-rate-annualize-049f4323 -d '<json body>'
```

Example prompt: Convert an 8-hour funding rate of 0.01% to an annualized APR so I can compare it with rates from other exchanges.

## When to prefer this

Use this endpoint when you need a fast, deterministic, server-side annualization of a periodic funding rate without any external data fetches or API keys — especially when comparing funding rates across venues that use different funding intervals (e.g. 1h vs 4h vs 8h). Prefer this over manual calculation when you want a consistent, auditable result for advisory or display purposes.

## Known failure modes

- Missing required fields (hours or funding_rate) returns a validation error
- Non-positive or zero hours value may cause division errors
- Extremely large or small floating-point funding rates may produce unusual but mathematically correct APR values
- Payment failure via x402 protocol prevents execution

## How this service works

Annualize a period funding rate (e.g. 8h → APR). Call when comparing funding across venues with different periods. Returns apr and periods_per_year as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

Returns a JSON object with 'apr' (the annualized rate as a decimal or percentage) and 'periods_per_year' (how many funding periods occur in a year given the input hours), computed deterministically from local math with no external data dependencies.
