Retrieve earnings call transcripts for public companies via Alpha Vantage, paid per-call with pathUSD on Tempo.
What it does
This MPP endpoint provides access to Alpha Vantage's Earnings Call Transcript API through the Locus payment proxy. You send a POST request with a stock ticker symbol and a quarter (in YYYYQN format, e.g. "2024Q1"), and receive the full earnings call transcript for that company and quarter. Payment is handled automatically via the MPP (Micropayment Protocol) at $0.008 per call, settled in pathUSD on the Tempo L2 network.
The endpoint is part of a broader Alpha Vantage suite exposed through Locus MPP that includes 26+ financial data endpoints covering intraday/daily/weekly/monthly time series, global quotes, symbol search, news sentiment, company fundamentals (income statement, balance sheet, cash flow, earnings), forex and crypto exchange rates, commodity prices, economic indicators, and technical analysis indicators (SMA, EMA, MACD, RSI, Bollinger Bands). All endpoints share the same per-call pricing of $0.008.
The OpenAPI 3.1.0 schema is well-documented with typed request bodies. The earnings-call-transcript endpoint requires two fields: "symbol" (stock ticker) and "quarter" (YYYYQN format). Note that the probe returned 404 on HEAD and GET — this endpoint only accepts POST requests, which is consistent with the OpenAPI spec. Upstream documentation is available at https://www.alphavantage.co/documentation/ and LLM-specific docs at https://beta.paywithlocus.com/mpp/alphavantage.md.

Quick start
curl -X POST https://alphavantage.mpp.paywithlocus.com/alphavantage/earnings-call-transcript \
-H "Content-Type: application/json" \

"quarter": "2024Q1"
}Endpoint
Quality
Full OpenAPI schema with typed request body and clear parameter descriptions. However, the probe did not capture a live 402 challenge (only POST is accepted, probe tried HEAD/GET), no example response is available, and crawled pages all returned 404 JSON errors. Pricing is inferrable from the OpenAPI x-payment-info but response shape is undocumented.
Warnings
- —Probe returned 404 on HEAD and GET — endpoint only accepts POST per the OpenAPI spec, so liveness could not be confirmed via the probe
- —No example response schema or sample response is provided in the OpenAPI spec
- —Currency address 0x20c000000000000000000000b9537d11c60e8b50 is assumed to be pathUSD with 6 decimals based on the Tempo method; if decimals differ, the $0.008 price estimate would be wrong
- —Upstream Alpha Vantage transcript coverage may not include all companies or all quarters
