Blockchain And Crypto x402 offerings

One ERC-8004 agent identity on one chain, with EVERY rating it received and the transaction of each — revoked ones published and marked, never hidden. This is the verification call: each row can be replayed against that chain's explorer. Input: `network`, a chain slug (base, avalanche, solana…), and `agent_id`, a counter on EVM chains and a base58 asset id on Solana, both as query parameters. An id the index never saw is a 404; free GET /search/{query} says which chains a bare id exists on.

describe.net over MCP (Streamable HTTP), stateless: the same global ERC-8004 reputation index as fourteen tools. Eight of them never charge — including `describe_check_wallet`, which tells you whether a wallet has anything worth paying for, and `describe_resolve`, which tells you what a bare string even IS (wallet, agent id, or both at once) before you pay to look one up on the wrong chain. The metered tools relay the x402 402 of the route behind them; `accepts` below is the cheapest of those, $0.01. No account, no API key: paying is the authentication.

The same wallet decomposition, plus a durable citable receipt: a stored row with `inputs_digest` and `policy_version` so you can later prove what the index said, under which scoring policy, on the day you decided. The only route in this API that writes. Use it when the decision has to be defensible to a third party (a dispute, an audit, a counterparty report); the plain lookup is cheaper when it does not. Input: `wallet` as a query parameter, and `snapshot=true`.

Reputation of one wallet, decomposed. Not the score — the score is public on-chain and you can average it yourself. What this buys is what the score is MADE of: how many distinct counterparties wrote it, how many times each one spoke, in which facet, dated on-chain, each with its transaction, across every chain we index. Substitute an EVM 0x address or a Solana base58 id for :wallet. Free first step, same subject: GET /wallets/:wallet/chains says whether there is anything worth paying for.

Reputation of one wallet across every chain the ERC-8004 index reads, decomposed. Not the score — the score is public on-chain and you can average it yourself. What this buys is what the score is MADE of: how many distinct counterparties wrote it, how many times each one spoke, in which facet, dated on-chain, each with its transaction, plus the caveats those numbers trigger. Input: `wallet` as a query parameter, an EVM 0x address or a Solana base58 id. A wallet the index holds nothing on is a 200 with a null score, not an error. Free first step, same subject: GET /wallets/{wallet}/exists says whether there is anything worth paying for.

The dated series of that wallet's reputation: how the score moved, when, and on which ratings — revoked ones included and marked. It answers the question a single number cannot: is this a wallet that earned its standing over time, or one that acquired it last week.

Convergence Alert: Detects when an entity triggers 3+ independent signal types from different analytical domains simultaneously. Why it matters: Individual signals can be noisy. Convergence from independent domains drops false positive probability dramatically. High score: 5+ signal types converging. Example: Protocol J: 4 signal types converge — insider_flow, utilization_risk, governance_apathy, yield_anomaly. | ZWING Intelligence (https://zwing.finance) — contact: v@zwing.finance, Telegram: @valery_zzz

Comprehensive risk and opportunity analysis for any crypto entity. Returns all active signals with full evidence across 50 signal types: smart money flows, DeFi risk, governance, token unlocks, yield anomalies, and cross-domain convergence alerts.
