# AgentDiet Multi-Engine SERP Grounding

> AgentDiet Multi-Engine SERP Grounding is a paid API for AI agents from status.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Runs a web search query through multiple search engines and returns grounded, distilled results optimized for minimal token usage in AI agent context windows.

## Facts

- Endpoint: GET https://status.agentdiet.dev/v1/multi-engine-serp-grounding?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-multi-engine-serp-grounding-c7396236
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_GybCA0K89rWv76c6WqqxY

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agentdiet-multi-engine-serp-grounding-c7396236
```

Example prompt: Search the web for 'latest AI agent frameworks 2025' and give me the grounded results compressed to fit in my context window without burning through my tokens.

## When to prefer this

Choose this endpoint when you need live web search grounding for an AI agent but are constrained by context window token limits. It is particularly valuable in agentic pipelines where raw SERP output would be prohibitively large, or when you need multi-engine coverage with a single $0.01 USDC call. Prefer this over direct search APIs when token compression (claimed ~85-91%) is a priority and you are already operating within a x402/L402 micropayment infrastructure on Base.

## Known failure modes

- Missing or empty query parameter returns malformed or empty data
- Invalid HTTP method (not GET or POST) returns schema validation error
- Payment failure or insufficient USDC balance results in 402 Payment Required
- Query too vague or unsupported language may return empty search results
- Rate limiting or upstream SERP provider outage may return 503 or degraded results
- Invalid input type (not 'http') triggers schema const validation error

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing distilled search results, a 'status' field confirming success, and an 'roi_proof' object showing the compression_ratio_pct achieved (e.g. 91.4% compression), demonstrating how much the token footprint was reduced compared to raw SERP output.
