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-credential-escrow-proxy-b4851f2d -d '<json body>'
```

Example prompt: Using DDG's credential escrow proxy, forward this JSON body as a POST request to the registered target service and return the response — I don't want to embed my API keys directly in this workflow.

## When to prefer this

Choose this endpoint when an AI agent needs to call a credentialed third-party API without embedding secrets in the agent's context or prompt. Ideal for automated workflows where credentials are pre-escrowed server-side and the agent only needs to supply the request body and method. Prefer over raw provider access when you want bounded, per-call micropayment billing via x402 USDC rather than managing API subscriptions.

## Known failure modes

- Invalid or missing 'input.type' constant (must be 'http') returns validation error
- Unsupported HTTP method (only POST/PUT/PATCH allowed) returns 400
- Credential not found in escrow for the target service returns auth failure
- Downstream service unreachable or returns error — status and body are forwarded as-is
- x402 payment not settled or insufficient USDC balance causes 402 rejection
- Malformed body for the selected bodyType (json/form-data/text) causes parse error

## 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, the proxied response 'body', the HTTP 'status' code from the downstream service, and a 'service' identifier string confirming which escrow proxy configuration was used.
