The skill document

Penny Web Search

Use PennyAPI when a task needs current information from the public web.

When to use

Use Penny for:

  • current or recently changed facts
  • web research
  • fresh sources and links
  • fact checking or verification
  • recent developments
  • questions where model knowledge may be stale

Do not use Penny when:

  • the user explicitly says not to access the web
  • the answer is timeless and does not need fresh information
  • the task is based only on user-provided material

Service

Origin: https://pennyregwatch.com

Paid search endpoint: https://pennyregwatch.com/v1/search

Price: $0.004 USDC per call

Network: Base (eip155:8453)

Payment protocol: x402

Preferred workflow with AgentCash

  1. Check the endpoint schema and current price before spending:
npx agentcash@latest check https://pennyregwatch.com/v1/search
  1. For a normal search, use POST:
npx agentcash@latest fetch https://pennyregwatch.com/v1/search -m POST -b '{"query":"YOUR SEARCH QUERY","limit":5}'
  1. GET is also supported:
npx agentcash@latest fetch 'https://pennyregwatch.com/v1/search?query=YOUR%20SEARCH%20QUERY&limit=5'

AgentCash handles the x402 challenge, wallet signature, payment, and retry.

Input guidance

Required:

  • query: natural-language web search query

Optional:

  • limit: number of results requested

Prefer specific queries that express the information need clearly.

Spending rules

  • Penny costs $0.004 per call.
  • Prefer one well-formed search before issuing additional calls.
  • Do not make duplicate searches unless the first result is insufficient.
  • Never fabricate a successful payment or result.
  • A failed non-2xx request should not be treated as fulfilled.

Result handling

Return useful facts from Penny's response and preserve source URLs when present.

Distinguish:

  • information returned by Penny
  • your own inference
  • information from other sources

For time-sensitive claims, prefer the freshest credible source in the returned results.

Troubleshooting

If the endpoint is not recognized:

npx agentcash@latest discover https://pennyregwatch.com

If AgentCash has not persisted Penny as a provider:

npx agentcash@latest add https://pennyregwatch.com

Do not guess alternate Penny endpoint paths. Use /v1/search.
