It is part of a broader suite of pay-per-call APIs offered by the same provider, all settled via the x402 protocol on the Base network using USDC. The specific endpoint path is `/api/v1/tax/1099/2021` and accepts POST requests.\n\nPricing is $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled inline via the x402 `X-PAYMENT` header — no API keys, accounts, or rate limits are required. The provider advertises uniform $0.02 pricing across all their endpoints. The x402 challenge was confirmed live, returning a proper 402 response with payment parameters including the USDC contract on Base (`0x8335...2913`) and a 300-second payment timeout.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no description of request/response formats, and no explanation of what data fields the 1099 endpoint returns or what input parameters it expects. The endpoint is confirmed live but its actual functionality and data quality cannot be verified from available materials.","tags":[],"capabilities":["tax-data","1099-form","irs-2021","x402-payment","usdc-base","pay-per-call","no-api-key"],"categories":["finance","tax"],"synonyms":["1099 tax form API","IRS 1099 data","tax year 2021","1099 lookup","tax information API","US tax form data"],"warnings":["No API documentation available — all doc pages return only 'Connect wallet' with no content","No OpenAPI or request/response schema provided; input parameters and output format are unknown","The specific endpoint path suggests 2021 1099 tax data, but this is inferred solely from the URL — no description confirms it","This endpoint is not listed on the provider's homepage among their advertised APIs, raising questions about whether it is actively maintained"],"endpointUrl":"https://lowpaymentfee.com/api/v1/tax/1099/2021","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/1099/2021","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid 402 x402 challenge, but there is no documentation, no OpenAPI schema, no request/response examples, and no explanation of what data is actually returned.
