Live vault figures read from chain — Live vault figures, read from chain 999

HTTP 402 x402 payment challenge — Unpaid agent call → HTTP 402 challenge ($0.01 USDC on Base)

Real settled payment and live tally — A real $0.01 settle on Base + the live tally

What the recording shows

pyd.fi landing and the live vault page — share price and TVL read straight from the HyperEVM vault contract (chain 999).
The agent surface: an unpaid GET /api/agents/yields returns HTTP 402 with a real x402 payment challenge — $0.01 USDC on Base, no account, no API key.
One real $0.01 USDC payment settled on Base, verifiable on BaseScan, followed by the live /api/x402/stats tally.
Caps enforced in code ($10,000 vault TVL · $1,000 per wallet) and the daily on-chain attestation at pyd.fi/attestations/latest.md.

Honest framing: no Base builder-code transaction attribution is claimed for today's activity — the builder code (bc_vpwmijxc) is wired into the app but has no user-facing Base transaction path yet. Everything shown here is live product behaviour and on-chain fact.
