It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, and utility services. All endpoints use the x402 protocol for payment, settling in USDC on the Base network.\n\nThe specific endpoint `/api/v1/tax/1099/2020` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The provider advertises no API keys, no rate limits, and instant access — you simply attach an x402 payment header to each call.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields or data the 1099 endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the lack of documentation means callers must discover the request format and response shape experimentally.","tags":[],"capabilities":["x402-payment","usdc-base","tax-data","1099-form","per-request-pricing","no-api-key","json-response"],"categories":["finance","tax"],"synonyms":["1099 tax data API","IRS 1099 lookup","tax form 2020","1099 information return","US tax data endpoint","micropayment tax API"],"warnings":["No documentation available — all doc/API/pricing/README pages return only 'Connect wallet' with no content.","No request or response schema provided; callers must discover the API contract experimentally.","It is unclear what specific 1099 data this endpoint returns or what input it expects.","Tax data APIs may be subject to regulatory requirements depending on jurisdiction and data sensitivity."],"endpointUrl":"https://lowpaymentfee.com/api/v1/tax/1099/2020","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/tax/1099/2020","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing, but there is zero documentation on request parameters, response schema, or what data is actually returned.
