External markets

Display-only GeckoTerminal data for non-Trancepad ERC-20s.

Trancepad indexes its own launches. The external market API adds display-only summaries and charts for other ERC-20s on Robinhood Chain, powered by GeckoTerminal. The app uses this on /trade when a token is not a Trancepad launch.

Display only

External market data is not Trancepad settlement. It does not sync receipts, does not prove balances, and must not be used as the sole input for automated trading. Show attribution when you surface third-party prices.

When to use which API

Trancepad token routes: GET /tokens/:address, chart, trades, holders for launches indexed by Trancepad (curve or graduated).
External market: GET /market/external/:address (+ /chart) when the address is a non-Trancepad ERC-20 and you need a price/chart snapshot for UI.

Endpoints

Address is required (checksum or lowercase hex). Symbol lookup is not supported. Missing pools return 404.

curl -sS "${API_URL}/market/external/0xToken"
curl -sS "${API_URL}/market/external/0xToken/chart?interval=1h"

Chart interval matches token charts. Sub-minute intervals coarsen to 1m. Responses are cached briefly (about three minutes for charts). Full field notes: docs/api.md.

Agents can call the same surface via MCP for agents (trancepad_external_market).
