## 🪙 Crypto Dossier **An x402-native market-intelligence endpoint.** One call returns a complete dossier on any crypto token — **by symbol or contract address** — merged from **8 independent sources** into one clean JSON schema, priced at **$0.001 per call**, payable by any agent. Built for autonomous agents, trading bots, and enrichment pipelines that pay-per-call over **x402** — no accounts, no API-key juggling, no rate-limit management. --- ### 💳 Access & payment Speaks **x402-v2 on Base**. Two ways in: **1 · Free trial — Sign In With X (SIWX).** Your first **5 calls are free**.

Resolved from Base registry 0x8004…a432. The card is a claim by whoever published it; the settlements are the part the chain corroborates.

Using Roundhouse, vet this ERC-8004 agent identity for me: what does its card claim, who
has rated it, and does its on-chain record support the claim?

Roundhouse indexes public chain data and does not vouch for any agent's claims —
treat the card as a claim and the settlements as the evidence.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

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