The endpoint accepts POST requests with a JSON body specifying a trading symbol (e.g., ETHUSDT, BTCUSDT), a time frame (e.g., 5m, 1h), and an array of indicator studies to compute. Each call returns timestamped indicator values along with metadata such as display name, category, and description. A GET variant is also available for single-indicator queries, and a separate `/ta/indicators/list` endpoint enumerates all supported indicators.\n\nPayment is handled via the x402 protocol on the Base network. Each call costs up to 1,000 base units of USDC (asset 0x8335…2913, 6 decimals), which equals $0.001 — a fraction of a cent per request. The payment is settled on-chain to address 0xe19c32d82d4cfb9d121fa04f9d22b11648f320f5. The endpoint returns a 402 challenge with an `exact` payment scheme when no X-PAYMENT header is provided.\n\nThe API is built on FastAPI (v0.1.0) and exposes an OpenAPI 3.1 spec at `/openapi.json`. Documentation beyond the auto-generated Swagger UI is minimal — there is no dedicated pricing page, README, or extended docs. The output schema in the x402 challenge describes a structured response with status, indicator type, symbol, time frame, metadata, and an array of timestamped values.","tags":[],"capabilities":["technical-analysis","crypto-indicators","ema","macd","bollinger-bands","trading-signals","time-series","x402-payment","base-network","usdc-settlement","fastapi","openapi-3.1"],"categories":["finance","crypto","data"],"synonyms":["crypto technical indicators","trading signals API","EMA API","MACD API","Bollinger Bands API","crypto charting data","x402 trading data","Mode Network indicators","algorithmic trading signals"],"warnings":["No documentation beyond auto-generated FastAPI Swagger UI","Full list of supported indicators not available in crawl — use /ta/indicators/list to discover them","Example response is inferred from the outputSchema in the x402 challenge, not from an actual API response"],"endpointUrl":"https://x402.mode.network/ta/indicators","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xe19c32d82d4cfb9d121fa04f9d22b11648f320f5","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://x402.mode.network/ta/indicators","description":"Mode-x402 is a complete library of signals and indicators for intelligent trading agents","outputSchema":{"input":{"type":"http","method":"POST","body_type":"json","body_fields":{"symbol":{"type":"string","description":"Trading pair symbol, e.g., 'ETHUSDT'"},"indicators":{"type":"array","items":{"type":"object","required":["kind"],"properties":{"kind":{"type":"string","description":"Type of indicator, e.g., 'ema', 'bbands', 'macd'"},"limit":{"type":"integer","description":"Number of data points to compute"}}},"description":"List of indicators to compute"},"time_frame":{"type":"string","description":"Time frame for the indicator, e.g., '5m', '1h'"}},"discoverable":true,"query_params":{},"header_fields":{}},"output":{"data":{"$schema":"https://json-schema.org/draft/2020-12/schema","properties":{"data":{"type":"array","items":{"type":"object","properties":{"id":{"type":"string","description":"Unique identifier for the indicator instance"},"meta":{"type":"object","properties":{"category":{"type":"string","description":"Category of the indicator"},"timezone":{"type":"string","description":"Timezone of the data"},"description":{"type":"string","description":"Description of the indicator"},"display_name":{"type":"string","description":"Display name of the indicator"}}},"symbol":{"type":"string","description":"Trading pair symbol"},"values":{"type":"array","items":{"type":"object","properties":{"value":{"type":["number","null"],"description":"Value of the indicator at the timestamp"},"timestamp":{"type":"string","description":"ISO format date time of the data point"}}}},"indicator":{"type":"string","description":"Type of indicator"},"time_frame":{"type":"string","description":"Time frame for the indicator"}}}},"status":{"type":"string","description":"Status of the request"}},"additionalProperties":false}}},"maxAmountRequired":"1000","maxTimeoutSeconds":60}]},"qualityScore":"0.720","qualityRationale":"The endpoint is live (402 challenge captured), has a full OpenAPI 3.1 schema with request/response definitions, and the x402 challenge includes a detailed outputSchema.
