Returns structured verdicts with confidence scores and current truth values.\n\n## When to Activate\n\nUse this skill whenever:\n\n- A user states a number as fact (\"the exchange rate is 0.92\", \"Bitcoin is at $60K\")\n- You are about to use training-data numbers in calculations or recommendations\n- A user asks \"is it true that...\" or \"can you verify...\"\n- You need a current price, rate, date, or statistic for an accurate response\n\n**Do NOT use for:** opinions, predictions, subjective claims, or questions about future events.\n\n## Workflow\n\n### Step 1: Extract the claim\n\nIdentify the specific factual assertion. Be precise.\n\n### Step 2: Check via MCP tool (preferred)\n\nIf `@agentutil/verify-mcp` is available:\n```\nverify_claim({ claim: \"The USD to EUR exchange rate is 0.92\" })\n```\n\n### Step 3: Fall back to HTTP\n\n```bash\ncurl -X POST https://verify.agentutil.net/v1/verify \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"claim\": \"The USD to EUR exchange rate is 0.92\"}'\n```\n\n### Step 4: Interpret the verdict\n\n| Verdict | Confidence | What to do |\n|---------|------------|------------|\n| `confirmed` | > 0.9 | Safe to use. Cite `current_truth` as the verified value. |\n| `confirmed` | 0.7-0.9 | Likely correct but note the uncertainty. |\n| `stale` | any | Data has changed. Use `current_truth` instead. |\n| `disputed` | any | Sources disagree. Present both sides. |\n| `false` | > 0.8 | Contradicts current data. Correct it. |\n| `unknown` | any | Could not verify. Say so honestly. |\n\n## Categories\n\n- `financial` — exchange rates, crypto prices, stock prices\n- `entity` — company info, population, founding dates\n- `geo` — timezones, geographic data\n- `factcheck` — general fact-checking\n\n## Pricing\n\n- Free tier: 25 queries/day, no authentication required\n- Paid tier: $0.004/query via x402 (USDC on Base)\n\n## Agent Discovery\n\n- MCP server: `@agentutil/verify-mcp` (npm)\n- ClawHub: `clawhub install claim-verify`\n- Agent Card: https://verify.agentutil.net/.well-known/agent.json","install":"clawhub install claim-verify","service":"https://agentutil.net","version":"2.0.1","services":["verify.agentutil.net"],"request_id":"87f083d3-7b33-43b7-a6c6-1077d3c1d159","description":"Verify factual claims against live data before using them in responses, calculations, or decisions.","display_name":"Verify Claim"}},"exampleRequest":{"name":"claim-verify"},"tags":["x402"],"displayCostAmount":"0.001","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.001/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_37JPIBxrXIT9QTkzD78cx","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.001","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Verifies factual claims against live data to confirm accuracy before using them in responses, calculations, or decisions.","exampleAgentPrompt":"Before you use that statistic in your answer, can you verify the claim 'global average temperature has risen by 1.2 degrees Celsius since pre-industrial times' against live data to make sure it's accurate?","exampleUseCases":null,"resultDescription":"The agent receives a structured verification result indicating whether the claim is supported, refuted, or unverified, along with supporting or contradicting evidence drawn from live data and a confidence indication.","failureModes":["Claim is too ambiguous or poorly formed to verify — returns validation error","Live data sources are unavailable or unreachable — returns service error","Claim pertains to a domain with insufficient live data coverage — returns low-confidence or unverifiable result","Payment of $0.001 USDC not provided or rejected — returns 402 Payment Required","Input schema missing required 'name' field set to 'claim-verify' — returns 400 Bad Request"],"whenToPreferThis":"Choose this endpoint when an AI agent needs to confirm the factual accuracy of a specific claim before using it in a response, calculation, or downstream decision — especially when the claim involves current statistics, recent events, or time-sensitive data.
