pay.snowsignals.io · pay.snowsignals.io

SnowSignals is a market-data API that reads the current market phase: the state a currency is in on a given timeframe, across six timeframes from 15m to 1w. TrendVane, the model behind it, tells you which phase the market is in. Bring your own strategy. Every phase ships with the numbers to reason about it — successor-transition probabilities and reward-vs-drawdown, each carrying its sample count. No account or signup, pay per call in USDC on Base chain over x402. The metadata and resolution-stats endpoints are free, so you can price a call and read the research before you spend a cent.

pass Valid AgentCard 10/10

Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).

partial Live JSON-RPC 15/25

Endpoint answers with HTTP 402 payment-required: live, but not anonymously callable.

            How to earn +10 points
          

Respond live on JSON-RPC

Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload. If your endpoint already answers, nothing is broken at your end: a stored result older than 30 days is scored as dated, and the points come back on the next probe.

fail Protocol version 0/10

No protocolVersion in card.

            How to earn +10 points
          

Declare protocolVersion

Add `"protocolVersion": "1.0"` to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

info JWS signature 0/10

Card is unsigned (most published agents are).

info Uptime track record 0/15

Only 0 probes so far, need ≥5 for an uptime grade.

fail Skill declaration 0/10

No skills declared in card. Hard to route to.

            How to earn +10 points
          

Declare your skills

Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags`. We canonicalise these into the global skill taxonomy on next probe.

partial Verified Identity 5/10

Provider declared: pay.snowsignals.io (https://pay.snowsignals.io). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

            How to earn +5 points
          

Verify your domain ownership

Claim your listing and add the DNS TXT record we generate. Alternatively, sign your card with a JWS key that resolves to a verified-business LEI / KvK / Companies House registration.
