## 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-seller-derivatives-data-feed-c5994cca
```

Example prompt: What are the current perpetual futures funding rate and open interest for ETH right now?

## When to prefer this

Choose this endpoint when your agent needs raw perpetual futures funding rate or open interest data for a specific crypto symbol in a single keyless, pay-per-use call. Prefer it over stitching together multiple free exchange APIs when you want consolidated derivatives data without API key management overhead. It is especially useful when combined with the rug-screening and liquidity drain endpoints on the same service to build a full picture of a token's tradability and market positioning.

## Known failure modes

- Symbol not found or unsupported — empty or error response
- Payment not included or invalid USDC x402 payment — 402 Payment Required response
- Upstream exchange data unavailable — partial or stale data returned
- Invalid symbol format — bad request error
- Rate limit or server overload on Render hosting — 503 or timeout

## How this service works

Rug protection and decision-ready intelligence for autonomous trading agents. Keyless by design: no signup, no API key — pay a cent per request in USDC (x402). The /alpha/launches LAUNCH RADAR discovers what just launched AND rug-screens every candidate in one call, ranked per-token verdicts — the proactive 'give me safe alpha' call. /vet gives a single-token go/no-go in ONE call by fusing a COMPOSITE rug score (GoPlus static analysis + a LIVE Honeypot.is buy/sell simulation + serial-rugger check) with our SELF-COLLECTED liquidity-drain trend — a rug-in-progress signal that exists nowhere for free because it requires collecting reserves over time. One call is cheaper than the inference tokens you'd burn stitching 4 free APIs, and it stops your agent losing its whole position to a honeypot. Also: /onchain/liquidity drain detector, /screen batch watchlist check, /brief market regime, and raw feeds (prices, stocks, DEX pools, launches, perp funding/OI).

## Output

Returns raw perpetual futures derivatives data for the requested symbol, including funding rate and open interest metrics from aggregated exchange sources, enabling agents to assess market positioning and funding costs.
