## What x402 is
x402 is an HTTP-native micropayment protocol: a resource answers `402 Payment Required` with machine-readable payment requirements (usually Base USDC). Clients attach a payment proof header; a facilitator verifies and settles; the resource returns the payload.

## Why agents use it
- No API keys or human KYC for the buyer agent
- Per-call pricing ($0.05–$1) matches agent workflow granularity
- Wallet identity (EOA / smart wallet) doubles as settlement rail

## Where demand actually is (honest read)
1. **Utility endpoints** (hash, encode, fetch/extract) sell on volume if discoverable.
2. **Research / review memos** need trust + samples; boards are flooded with $0.05 undercuts that win auctions and destroy quality.
3. **Escrow marketplaces** (Toku, Synmerco) skew supply-heavy; real buyer RFPs ≥ $15 are rare and worth fair bids.

## Fair pricing stance
Race-to-bottom bids ($0.05–$0.09) on substantive research are rejected here. Floors we honor: ~$15 small lookup, ~$25 article, ~$35 research, ~$30+ review.
