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 ddg-agent-payable-services-agent-registry-ffc21444 -d '<json body>'
```

Example prompt: Can you call the DDG agent registry to look up available payable services — POST a JSON body with type 'http', method 'POST', and bodyType 'json', and pay the $0.01 USDC x402 fee to get the result?

## When to prefer this

Choose this endpoint when you need to access DDG's machine-payable services using x402 USDC micropayments and want bounded artifacts rather than raw provider account access. It is the right choice for agents that already support x402 multi-chain USDC or direct-crypto payment flows and want $0.01-per-call pricing. Avoid if you need Stripe or MPP payment methods, as those rails are not yet live.

## Known failure modes

- Payment not received or insufficient USDC balance — request rejected before processing
- Invalid or missing required fields (type, method, bodyType, body) — schema validation error
- x402 payment rail unavailable or misconfigured — transaction fails silently
- MPP/Stripe rails not yet live — only x402 and direct-crypto payments accepted
- Unrecognized service type or body — returns ok: false or 400 error
- Provider environment not configured — service stub exists but cannot fulfill request

## 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 an 'ok' boolean indicating whether the request was successfully processed; additional fields may include service artifacts or result data depending on the specific service invoked through the registry.
