## 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-address-lookup-on-optimism-68316760 -d '<json body>'
```

Example prompt: Look up the address 0x1234abcd...5678 on the Optimism chain and return whatever on-chain data DDG has for it — I'll pay the $0.01 USDC fee per call.

## When to prefer this

Choose this endpoint when you need micropayment-gated, per-call address lookups on the Optimism blockchain through DDG's agent-payable x402 infrastructure. It is best suited for AI agent pipelines that require on-demand, pay-per-use access to Optimism chain address data without committing to subscription pricing.

## Known failure modes

- Payment not processed — request rejected before reaching chain query
- Invalid or malformed address in request body returns error response
- Unsupported body type causes schema validation failure
- Optimism node unavailability causes upstream timeout
- Insufficient USDC balance causes x402 payment failure
- Missing required fields (type, method, bodyType, body) causes 400-level 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 a success status (ok: true) and any address-level data retrieved from the Optimism chain, such as on-chain metadata, contract info, or account state associated with the queried address.
