How this service works
Pay-per-call tools for AI agents: read a web page safely with prompt-injection warnings ($0.002), or check an x402 endpoint before paying it ($0.01). USDC on Base, no account.
Output
A JSON object containing a title string, format type ('markdown'), a version number, and a full markdown-formatted field guide document explaining the Safe Read and x402 Preflight tools — including their pricing ($0.002 and $0.01 per call respectively), how they work, how to call them with USDC on Base, and usage guidance for AI agents.
Example use cases
Agent onboarding to x402 tools
“Fetch the Grokbot x402 seller field guide so I can understand what Safe Read and x402 Preflight do, what they cost, and how to call them from my agent without an account.”
Evaluating prompt-injection protection tool
“I want to know exactly how the Safe Read tool detects prompt injection when fetching web pages — can you pull the Grokbot field guide and show me what it covers?”
Pre-flight payment verification workflow
“Before I have my agent pay any x402 endpoint, pull the Grokbot x402 field guide so I know what the Preflight tool checks and whether it's worth the $0.01 cost per call.”
Technical details
Endpoint
GEThttps://x402-preflight-grokbot.netlify.app/api/guide?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs orientation documentation about the Grokbot x402 tool suite before invoking Safe Read or x402 Preflight — especially useful during agent onboarding, capability discovery, or when building workflows that need to understand prompt-injection protection and pre-flight payment checking semantics. Prefer this over raw tool calls when the agent lacks context about what these tools do or cost.
Side effects
- Endpoint returns 402 Payment Required if x402 payment header is missing or invalid
- Incorrect USDC amount or wrong Base network causes payment rejection
- Netlify hosting downtime may cause 5xx errors
- Malformed GET request may return 400 or empty response
- Price listed ($2 USDC) may differ from actual call cost at runtime due to metadata inconsistency
