  title: Gloom Datasets Reference API
  version: '2026-11-10'
  description: 'Gloom Datasets API. Authenticate with a `gds_` key. Prices and limits: https://gloom.sh/datasets/pricing. Changes: https://gloom.sh/datasets/docs/changelog.


    Every response is `{data, meta}` and every error `{error: {type, code, message, param, requestId, docUrl}}`. Dataset routes sit directly under /v1; the catalog, account and reference routes under /v1/datasets. Company routes take symbols=, listings in any notation (AAPL, BRK-B, AIR.PA, VOD:XLON), as many as the route''s x-symbols.max: each item names its canonical listing, meta.symbols reports every input, and a listing the dataset does not know is free. Paths renamed in 2026-10-23 answer 308 to their new path until 2027-01-23 (x-redirects). Gloom Datasets keys and Gloom Pro keys are different keys for different APIs: each is refused by the other''s routes. Every route is also a tool of the MCP server at https://api.gloom.sh/v1/datasets/mcp (Streamable HTTP; x-mcp), with the same key and price. No key? Pay each call with x402: a call with no key answers 402 with its price in the PAYMENT-REQUIRED header; pay it in USDC on Base ($0.03 a credit) and send the same request with PAYMENT-SIGNATURE (x-x402, https://gloom.sh/datasets/docs/x402).'

  x-guidance: 'Gloom Datasets sells financial and alternative datasets (SEC filings, fundamentals, options, macro, hiring, GPU prices and more), one JSON route per dataset under /v1. Every route is paid per call with x402, in USDC on Base, with no account: a request with no payment answers 402 and its PAYMENT-REQUIRED header holds the price; the same request with a signed PAYMENT-SIGNATURE header is answered and then settled. A credit costs $0.03; each route''s price is in its x-payment-info, and routes that take symbols= (AAPL,MSFT) charge each listing the dataset holds. GET /v1/datasets lists the datasets and GET /v1/datasets/{id}/sample answers a dataset''s free sample. Parameters, limits and response schemas are described per route.
