Predge - Signed Attestations
GET https://api.predge.io/v1/sports/attest/:league/:eventId
Listed in PayAI
Cryptographically SIGNED settled-SPORTS-outcome ATTESTATION for one game (path params: league — one of nba|wnba|nfl|college-football|mlb|nhl|mls|epl|champions-league|laliga — and eventId, an ESPN event id). Returns the SETTLED result (winner, final score, completed) as an ed25519-signed envelope verifiable OFFLINE against the SAME published key as /v1/attest. Optional query param: winner (team abbreviation) — adds correct (true iff it matches the settled winner, null while unsettled). Data source: ESPN's public scoreboard (no key, no account). Outcome-verified truth, not a prediction — the tamper-evident settled outcome a betting/trading agent needs for settlement, dispute, or a verifiable track record. 404 (not charged) for an unknown league or event id.

# HTTP/1.1 402 Payment Required: price, asset and payTo are in the responseEstimated calls per day
Paid calls to api.predge.io's tracked endpoints each day, estimated from the 30-day totals the x402 catalogues report. Each bar is the change in that 30-day total since the day before, plus the calls that left the 30-day window (taken as an average day). It is an estimate: Hagglyai does not measure or pay for these calls.
