## 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 ddg-http-headers-extraction-service-5adeff2d -d '<json body>'
```

Example prompt: Can you inspect the HTTP headers that come back when I make a JSON POST request with body {"userId": 42} — I want to see what headers are being sent or echoed.

## When to prefer this

Choose this endpoint when you need to programmatically inspect or extract HTTP headers from a POST, PUT, or PATCH request in a lightweight, pay-per-call fashion via x402 USDC micropayment. It is suited for debugging, auditing, or validating request headers without needing to set up your own proxy or inspection infrastructure.

## Known failure modes

- Missing required fields (input.type, input.method, input.bodyType, input.body) returns a validation error
- Unsupported HTTP method (e.g. GET) returns an enum validation error
- Payment not completed via x402 rail returns a 402 Payment Required response
- Malformed body type results in schema rejection
- Network timeout on the upstream request returns an error response

## How this service works

Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.

## Output

Returns a JSON object with ok: true and the extracted HTTP headers from the specified request, allowing agents to inspect what headers are present or echoed for a given HTTP POST, PUT, or PATCH call.
