How this service works

Goldsky Feeds: onchain data over REST. Formerly Edge Data / Data APIs; existing URLs and keys keep working. - **Wallet feeds**: one wallet's token transfers or balances across chains, with USD values (`/feeds/wallets/transfers`, `/feeds/wallets/balances`). - **Tokens**: metadata and current USD price for up to 100 `chain:token_address` pairs per request (`/feeds/tokens`). - **Prediction markets** (Polymarket, on Polygon): Activity, Positions and Balances (`/polymarket/*`). - **Chain datasets**: Blocks and Chain head for each supported chain (`/blocks/{chain}`, `/blocks/{chain}/head`). Base URL: `https://edge.goldsky.com/data`. Every endpoint is a `GET` that returns JSON. ## Authentication Send your Feeds API key in the `x-api-key` header, as the `?key=` query parameter, or as `Authorization: Bearer <key>`. Get it at [app.goldsky.com](https://app.goldsky.com) under **Feeds → API keys**. One key works for every endpoint; an invalid key gets `401`. ## Billing Requests made with a key bill compute units (CUs) at $10 per million: - Wallet feeds and Tokens: 35 CUs per request. - Prediction markets and Chain datasets: 1 CU per row returned. Chain head is 1 CU per call. Errors are not billed, and a Prediction markets or Chain datasets request that returns no rows costs nothing. Rate limits are set per plan (`429` when exceeded); Goldsky support can raise them. ## Pay per request with x402 No account or key needed. A request without a key gets `402` with an x402 v2 challenge in the `PAYMENT-REQUIRED` header (base64 JSON; the body carries the same challenge). Pay in USDC through Circle Gateway and retry. Each payment is a $0.005 prepaid top-up, tied to the paying wallet and shared with Edge RPC, that later requests spend down: - Wallet feeds and Tokens: $0.00035 (350 atomic USDC) per request. - Prediction markets and Chain datasets: $0.00001 (10 atomic USDC) per request, whatever the row count. The payment flow is in [x402 nanopayments](https://docs.goldsky.com/edge-rpc/capabilities/x402).

Output

Returns a JSON array of token objects, each containing the token address, chain identifier, chain family, token name, symbol, decimals, logo URL, USD price, and the timestamp of when the price was last updated. Null values appear for fields that are unavailable for a given token.
