Predge Whale Data is a live pay-per-call API on Base mainnet. An agent hits an endpoint, gets HTTP 402 with machine-readable price + schema, pays $0.005–$0.03 USDC, and receives JSON. No key, no account; the facilitator sponsors gas so a USDC-only wallet transacts. 17 paid routes today. The moat: win rates come only from resolved markets, and /v1/attest returns the settled outcome as an ed25519-signed, offline-verifiable attestation — the "was this signal right, and here's the proof" primitive nothing else in x402 sells.
