Cryptographically SIGNED WALLET TRACK-RECORD attestation (path param: 0x… wallet address; optional query param: window = 7d|30d, default 30d). Returns the wallet's RESOLVED-market-only record — win_rate, Wilson 95% lower bound, edge over entry price, conviction_score, volume, and a verdict (verified_smart_money | positive_edge | no_proven_edge) — as an ed25519-signed envelope verifiable OFFLINE against the SAME published key as /v1/attest. Every other tool shows a self-reported or scraped win rate you must trust; this SIGNS it, so a copy-trading platform, a fund proving a track record to an allocator, or an agent sizing a copy can verify the record without trusting this endpoint. Win rate is computed from resolved markets only (a trade wins when its side equals the market's eventual resolution). 404 (not charged) when the wallet has no resolved trades in the window.

Show the prompt

Using Roundhouse, look up the x402 service Predge · Signed Attestations and tell me whether it is
worth paying: what a call costs, whether the endpoint answered when last probed, and what
its payment record actually shows.

curl -s 'https://api.roundhouseai.io/v0/endpoints?q=Predge%20%C2%B7%20Signed%20Attestations'
curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>'

Then call it: read the price from the live 402 at https://api.predge.io/v1/wallets/:address/attest, never from
a cached figure, and pay with an x402 client.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402,
or use an organization key from https://roundhouseai.io/dashboard/team.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
