## 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 stillos-edge-gate-strategy-grader-966efdf8 -d '<json body>'
```

Example prompt: Can you grade my trading strategy's settled track record — I need to know if it's REAL_EDGE or just REGIME_LUCK — and make sure the verdict is fee-adjusted, out-of-sample tested, and comes back with a signed receipt I can verify on-chain?

## When to prefer this

Choose this endpoint when you need a third-party, cryptographically signed, economically bonded verdict on a trading strategy's track record — particularly when the verdict must be fee/slippage-adjusted, out-of-sample validated, and publicly disputable on-chain. Prefer it over generic backtesting tools when auditability, non-repudiation, and fail-closed classification are required.

## Known failure modes

- Insufficient historical data returns INSUFFICIENT_DATA verdict rather than an error
- Malformed or missing track record body results in 4xx validation error
- Payment not included or invalid USDC amount returns 402 Payment Required
- On-chain bond verification unavailable may delay signed receipt
- Disputed verdict initiates slash process at /notary/dispute rather than returning a new verdict

## How this service works

StillOS Edge-Gate — grade a settled strategy track record: fail-closed REAL_EDGE|REGIME_LUCK|NEGATIVE_EV|INSUFFICIENT_DATA verdict, out-of-sample + fee/slippage adjusted, Ed25519-signed receipt. Backed by a $10 on-chain correctness bond, up to $1 slashable per proven-wrong verdict -- verify at /notary/bond, dispute at /notary/dispute.

## Output

Returns a fail-closed verdict string (one of REAL_EDGE, REGIME_LUCK, NEGATIVE_EV, or INSUFFICIENT_DATA), an out-of-sample and fee/slippage-adjusted performance summary, an Ed25519-signed receipt for tamper-evident verification, and a reference to the $10 on-chain correctness bond (up to $1 slashable per proven-wrong verdict) verifiable at /notary/bond.
