## 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 aether-opportunity-score-63084f79 -d '<json body>'
```

Example prompt: Score the seed-stage opportunity called 'NovaTech AI' — it has pillars around team, market size, and traction, and I want to flag red flags 2, 5, and 9. Give me the score and whether I should investigate.

## When to prefer this

Choose this endpoint when you need a structured, scored verdict on a named investment or business opportunity — especially when you have explicit funding stage, assessment pillars, and specific red flag indices to evaluate. Prefer this over generic due diligence tools when working in the Base/x402 ecosystem and needing a pay-per-call micropayment-compatible scoring API.

## Known failure modes

- Missing required opportunityName returns validation error
- Invalid stage value outside enum returns 400 bad request
- redFlagIndices values outside 1-15 range rejected
- pillars array exceeding 7 items rejected
- Payment failure via x402/USDC returns 402 Payment Required
- Malformed JSON body returns 422 unprocessable entity

## How this service works

Pay-per-call Base onchain data, token risk verdicts and x402 payability audits over x402 (USDC on Base).

## Output

Returns a numeric score (integer) representing the opportunity's quality or risk level, along with a recommendation string such as 'investigate', 'pass', or 'proceed', helping the agent decide on next steps.
