Chord

Chord Agents and status API

What an agent starts from: the chain directory (which capability lives on which route, per chain), the hosted MCP server, per-chain health, the public status history, and how much agent traffic each chain sees.

  title: Chord Agents and status API
  version: '2026-10-05'
  summary: Trade, data and agent endpoints for eight EVM chains (Ethereum 1, Arbitrum One 42161, Base 8453, BNB Chain 56, Avalanche 43114, Monad 143, Arc 5042, Robinhood Chain 4663) and Solana (data and swaps).
  description: 'Chord is a non-custodial trading app and on-chain data index. The API has three kinds of endpoint:


    - **Trade**: `/quote` finds the best route across every venue on the chain; `/swap` turns it into a transaction you sign yourself. Chord never holds funds or keys.

    - **Read**: every swap on the chain, rolled up by token, venue and hour, from Chord''s own index — tokens, launches, holders, top wallets, portfolio PnL, liquidity positions and pools. No key needed. Avalanche, Base, BNB Chain, Arbitrum One and Ethereum have the same rollups under `/chains/{chain}/*`; Solana has its own data family under `/chains/solana/*` (base58 addresses, case-sensitive) and its swaps under `/sol/trade/*`.

    - **Agent**: the analyst (`/ask`) and the streams.


    Amounts are decimal strings in the token''s smallest unit. Timestamps are Unix seconds unless the field is `updatedAt` (milliseconds). `GET /portfolio/{wallet}` and `/portfolio/{wallet}/activity` differ on both: amounts there are in whole tokens and every time is in milliseconds. Reads answer anonymous callers at 60 requests a minute per IP; an `X-API-Key` header raises that to your plan. Every non-2xx body is `{ error, message }`.'
