## 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 vectorbuildhq-agent-intel-resource-dossier-aba5fe99 -d '<json body>'
```

Example prompt: I need to pick the best x402 resource for a data enrichment task — can you run a full resource dossier, score and compare the available options, and tell me which one to call next along with a fallback if it fails?

## When to prefer this

Choose this endpoint when an agent needs to autonomously select the best x402 resource for a task from multiple candidates, especially when reliability, scoring, and fallback planning are critical. It is most valuable in multi-step agentic pipelines where incorrect resource selection could waste spend or cause task failure. Prefer it over manual resource selection when the agent must verify, compare, and get next-call guidance in a single call.

## Known failure modes

- No suitable x402 resources found for the given task — returns empty or low-confidence dossier
- Task description too vague to meaningfully score or compare resources
- All candidate resources fail verification — dossier returned with only fallback guidance
- Payment failure ($0.75 USDC) results in 402 response and no dossier
- Upstream resource metadata stale or unavailable, leading to incomplete scoring

## How this service works

Discover, verify, score, compare, and select the strongest x402 resource for a task, with fallback and next-call instructions.

## Output

Returns a structured dossier including scored and ranked x402 resources, the recommended best match for the given task, verification status of candidates, fallback resource options, and next-call instructions for the agent to proceed.
