# AgentDiet Preflight Web Search

> AgentDiet Preflight Web Search is a paid API for AI agents from preflight.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Executes a live web search query and returns token-compressed results, surfaced through the agentdiet.dev preflight infrastructure.

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-preflight-web-search-af9eb73c
```

Example prompt: Search the web for the latest news on ERC-8004 identity standards and give me a token-efficient summary of what you find.

## When to prefer this

Prefer this endpoint when your agent needs live, grounded web search results with minimal token overhead — especially in token-constrained pipelines or when you need recent information about niche technical topics like x402, ERC-8004, or agent interoperability standards. It is priced at $0.01 USDC per call and returns compressed results, making it cost-effective for high-frequency grounding tasks.

## Known failure modes

- Missing or empty 'query' parameter returns empty or irrelevant results
- Invalid 'type' or 'method' field causes schema validation failure
- Payment failure (x402) blocks the request if USDC balance is insufficient
- Upstream search source (Google News RSS or HackerNews Algolia) unavailable causes partial or empty data
- Rate limiting or quota exhaustion on the underlying search provider

## How this service works

Automated 8-gate pre-flight readiness auditor for x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0 agent cards, OASF records, and ERC-8004 identity.

## Output

Returns a JSON object with a 'status' field ('ok'), a 'data' object containing search results, and a 'roi_proof' object including a compression_ratio_pct value (e.g. 91.4%) indicating how much token bloat was removed from the raw results.
