## 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 quietsignal-public-data-hire-developer-data-extract-7c037182 -d '<json body>'
```

Example prompt: Pull the hiring and developer facts for wallet 0xABC123 using the swarmwage protocol and the 'hire' capability from QuietSignal's public data — I want to see what opportunities or developer signals are associated with that address.

## When to prefer this

Choose this endpoint when you need independent, read-only, machine-readable facts about wallets, developer profiles, or on-chain hiring opportunities in the swarmwage ecosystem and are willing to pay $0.01 USDC per call over HTTP 402 on Base. Prefer it over general blockchain explorers when you specifically need hiring or developer-signal rollups rather than raw transaction data.

## Known failure modes

- Missing required fields ('params', 'protocol', or 'capability') returns a 422 validation error
- Payment not provided or insufficient USDC triggers HTTP 402 payment required
- Unknown or unsupported capability/protocol combination may return empty or error response
- Invalid buyer_id EVM address format may cause request rejection
- Rate limiting or network issues on the IP-addressed host may cause timeouts

## How this service works

QuietSignal Public Data: independent, read-only rollup, wallet, opportunity, and developer-data facts for agents, paid per request with USDC over HTTP 402 on Base.

## Output

Returns a flexible JSON object containing read-only rollup facts relevant to the requested capability — which may include wallet data, hiring opportunities, developer signals, or protocol-specific facts depending on the 'capability' and 'params' provided. The response schema is open (additionalProperties: true), so the shape varies by capability.
