## 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 oblique-markets-agentcore-seller-router-2d8fb5d7 -d '<json body>'
```

Example prompt: Find me the top 3 sellers who can handle a competitive crypto research task for under $2.00, using the x402:base payment rail, and return the result as JSON.

## When to prefer this

Use this endpoint when an AI agent needs to delegate a task to a marketplace seller and wants a vetted, ranked shortlist with live pricing and health rather than a raw seller list. Prefer it over generic marketplace search when you need payment rail negotiation (x402 or MPP), session handoff for multi-turn workflows, and receipt binding for auditability. Best suited for agentic pipelines that need to stay within a budget cap and require MCP-compatible seller schemas for downstream tool calls.

## Known failure modes

- No sellers available for the given task constraints — returns empty shortlist or 404-equivalent
- Price cap too low — no sellers meet the budget, returns filtered-out result with explanation
- Invalid preferred_rail enum value — returns 400 validation error
- x402 payment not fulfilled or underpaid — request rejected before routing occurs
- Seller health checks time out — partial list returned with degraded-health warnings
- Malformed seller_delivery_receipt — binding fails with schema validation error

## How this service works

Use when an agent needs to pick which paid agent service to call for a task. Returns a ranked top-three shortlist of paid agent services with live health, prices, x402 and MPP rails, MCP schemas, qualified session handoff and receipt binding. $0.01.

## Output

Returns a ranked shortlist of up to three sellers, each with live health status, current price quotes, supported payment rail details, MCP-compatible schemas, a qualified session handoff token, and a receipt binding for auditability. The response format can be JSON, Markdown, or plain text as requested.
