## 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 gpt-5-5-x402-agentcore-integration-kit-07f4c0da -d '<json body>'
```

Example prompt: Generate an AgentCore integration kit for the GPT-5.5 x402 gateway at https://gpt55.558686.xyz — my agent is called 'ResearchBot', my buyer goal is 'summarize documents', and I want to cap spending at $0.006 USDC per call.

## When to prefer this

Choose this endpoint when you need ready-to-use integration scaffolding — AgentCore, MCP, CDP Bazaar, curl, or x402 buyer code — for connecting to the GPT-5.5 x402 gateway, rather than making a direct chat/text completion call. Ideal for agent developers bootstrapping payment-aware LLM integrations quickly without writing boilerplate x402 protocol code from scratch.

## Known failure modes

- Missing required 'input.type' or 'input.method' fields returns a 400 validation error
- URL or base_url exceeding 2048 characters is rejected
- Invalid max_usdc_per_call outside 0.000001–100 range returns validation error
- x402 payment not provided or incorrect amount returns 402 Payment Required
- Service temporarily unavailable returns 5xx error
- Query params with additional unexpected properties are rejected due to additionalProperties:false

## How this service works

Low-price OpenAI-compatible GPT-5.5 chat completions and text tools over x402 USDC on Base: $0.0001 compact requests, $0.066667 true max-output requests, no subscription.

## Output

A JSON object with ok=true, a tool name ('x402AgentCoreIntegrationKit'), and a summary string describing generated integration snippets for AgentCore Gateway, CDP Bazaar, MCP, curl, and x402 buyer code — ready to drop into an agent or script that pays per GPT-5.5 request via x402 USDC.
