api.qist.info · api.qist.info

Compute zakat due on wealth: cash, gold, silver, business inventory, receivables, crypto and stocks, less deductible liabilities. Returns the nisab threshold under BOTH the gold (85g) and silver (595g) standards and flags when they disagree, since the choice changes who owes. Supports lunar (2.5%) and solar (2.577%) years. Deterministic — you supply metal prices, so you control the source. Educational calculation, not a fatwa.

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.

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: api.qist.info (https://api.qist.info). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.

3 evidence caveats

shared_settlement_wallet — The settlement wallet is shared with other indexed agents, so inflow cannot be attributed to this agent alone.

Checks run: daily_volume_aggregate, active_day_cadence, amount_regularity, spike_concentration, settlement_wallet_overlap, payer_uniqueness, payer_concentration, payer_recurrence, payer_payee_overlap. Derived from agent_revenue_daily, agents.payment_wallet, agent_payment_transactions. Measured 2026-08-19.

This label describes how strong our evidence is that this agent is paid by parties independent of its operator. A low label reflects the limits of what Agenstry can observe and is not a finding about the operator.

Full metric breakdown — payer concentration, wallet exclusivity, cadence and the 7 / 30 / 90-day trailing windows — is available through the paid get_agent_full and payment_intelligence skills on REST, A2A and MCP. API docs →
