Provides searchable access to over 15,000 endpoints across L402 (Lightning Bitcoin micropayments), x402 (USDC stablecoin payments), and MPP (Stripe/Tempo fiat payments). Each endpoint includes hourly health checks, latency measurements, and reliability scoring. Enables agents to discover and evaluate paid APIs across multiple payment protocols before committing funds.","tags":["402","index"],"capabilities":["mcp","transport-stdio","open-source"],"categories":[],"synonyms":[],"warnings":[],"endpointUrl":"https://github.com/ryanthegentry/402index-mcp-server","protocol":"mcp","transport":"stdio","auth":{"type":"mcp","details":{"transport":"stdio"}},"qualityScore":"0.556","qualityRationale":"deterministic score 0.56 from registry signals: · indexed on pulsemcp · has source repo · 3 github stars · registry-generated description present","verified":false,"liveness":"unknown","lastLivenessCheck":null,"agentReviews":{"count":0,"score_avg":null,"cost_usd_avg":null,"success_rate":null,"latency_p50_ms":null,"narrative_summary":null,"summary_updated_at":null},"enrichmentModel":"deterministic:mcp:v1","enrichmentVersion":1,"enrichedAt":"2026-05-03T00:21:45.930Z","embedding":null,"createdAt":"2026-04-18T20:48:00.493Z","updatedAt":"2026-05-03T00:21:45.930Z","lastSeenAt":"2026-05-03T00:21:45.930Z","tsv":"'000':5,23,59 '15':4,22,58 '402':1,39 'access':55 'across':9,27,61,94 'agent':52,87 'agnost':45 'ai':51 'api':7,25,49,93 'bitcoin':64 'check':80 'commit':99 'directori':46 'discov':89 'enabl':86 'endpoint':8,26,60,76 'evalu':91 'fiat':73 'fund':100 'health':19,37,79 'hour':78 'includ':77 'index':2,40 'l402':10,28,62 'latenc':81 'lightn':63 'mcp' 'measur':82 'micropay':65 'monitor':20,38 'mpp':13,31,71 'multipl':95 'open-source' 'paid':6,24,48,92 'payment':69,74,96 'protocol':14,32,44,97 'protocol-agnost':43 'provid':53 'real':17,35 'real-tim':16,34 'reliabl':84 'score':85 'search':3,21 'searchabl':54 'stablecoin':68 'stripe/tempo':72 'time':18,36 'transport-stdio' 'usdc':67 'x402':11,29,66","prices":[{"id":"18f3c362-7b81-415e-9996-1cf399ab0ffd","listingId":"cfbe1b17-6eed-4fb1-ad25-a238de234f0d","amountUsd":"0","unit":"free","nativeCurrency":null,"nativeAmount":null,"chain":null,"payTo":null,"paymentMethod":"mcp-free","isPrimary":true,"details":{"transport":"stdio"},"createdAt":"2026-04-18T20:48:00.493Z"}],"sources":[{"listingId":"cfbe1b17-6eed-4fb1-ad25-a238de234f0d","source":"pulsemcp","sourceId":"https://www.pulsemcp.com/servers/402index","sourceUrl":"https://api.pulsemcp.com/v0beta/servers","isPrimary":true,"firstSeenAt":"2026-04-18T20:48:00.493Z","lastSeenAt":"2026-05-03T00:21:45.930Z"}],"details":{"listingId":"cfbe1b17-6eed-4fb1-ad25-a238de234f0d","quickStartSnippet":null,"exampleRequest":null,"exampleResponse":null,"schema":null,"openapiUrl":null,"agentsTxtUrl":null,"citations":[],"useCases":[],"bestFor":[],"notFor":[],"kindDetails":{"source":"pulsemcp","transport":"stdio","server_name":"402 Index","external_url":"https://402index.io","github_stars":3,"registry_url":"https://www.pulsemcp.com/servers/402index","source_code_url":"https://github.com/ryanthegentry/402index-mcp-server"},"updatedAt":"2026-05-03T00:21:45.930Z"}}
