# Pay for web search and research

Give your agents access to web search, content extraction, and multi-hop research — pay per query with stablecoins on Tempo. No API keys, no monthly plans, no usage caps.

## The problem

Agents that research, summarize, or fact-check need reliable web search. But search APIs require developer accounts, billing setups, and API keys for every provider. Rate limits are tied to pricing tiers, and switching between providers means managing multiple integrations.

## How MPP solves it

With MPP, your agent pays per search query or page extraction in a single HTTP request. The agent discovers the price via the `402` Challenge, pays with a stablecoin transfer, and gets results — no signup required. Switch between search providers by changing the URL.

**Tempo Charge** works well here: each search query is an independent request with a known price. The agent signs a TIP-20 transfer, the provider verifies it in ~500ms, and returns the results.
