Proxies metric time-series data submission to Datadog's v1 series endpoint, billing per call via x402 micropayment

## Facts

- Price: $0.002/call
- Payment: x402

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 httpay-xyz-api-gateway-datadog-metrics-series-0593fc9e -d '<json body>'
```

Example prompt: Submit a gauge metric called 'app.response_time' with value 142.5 at the current timestamp, tagged with host:webserver-01 and env:production, to Datadog.

## When to prefer this

Use this endpoint when you need to submit custom metrics or time-series data to Datadog without managing Datadog API credentials directly, paying per call via x402 USDC micropayments instead of a subscription. Ideal for lightweight, infrequent metric submissions or agent-driven monitoring pipelines.

## Known failure modes

- Invalid metric payload structure returns 400 Bad Request
- Missing or malformed series data causes rejection
- Datadog backend unavailable returns 502 or 503
- x402 payment failure blocks request before forwarding
- Rate limiting by upstream Datadog API returns 429
- Timestamp too far in the past or future may be silently dropped by Datadog
