# Send the signed quote

Relays a transaction Chord quoted in the last three minutes, signed by the wallet it was quoted for — anything else is refused. Chord sends it to several RPC providers and again every 2 seconds until it lands or its blockhash expires; a `jupiter_meta` order goes through Jupiter's execute endpoint instead (Jupiter or the market maker adds its signature). Then poll `/sol/trade/tx/{signature}`.

**Open to everyone** since 2026-10-15, no key needed (an `X-API-Key` raises the rate limit). `/sol/trade/config` says whether the lane is on for the caller; when it is off the other routes answer `503 TRADE_NOT_ENABLED`.

A quote is SOL against one token, bought or sold. For every quote Chord builds, for **your wallet**, the transaction of each route — `direct` (Chord's own router: Raydium AMM v4 / CPMM / CLMM, Orca Whirlpool, Meteora DLMM / DAMM v2, Meteora DBC, Raydium LaunchLab, pump.fun, PumpSwap; up to two pools), `jupiter` (Jupiter's swap API, no Jupiter fee) and `jupiter_meta` (Jupiter's order: Metis, its RFQ market makers, DFlow, OKX; Jupiter's fee inside the amount) — simulates each on the chain and returns the one that leaves the wallet with the most: tokens for a buy, SOL for a sell, after every fee. Ties go to `direct`, then `jupiter`. A route handing back under half of the input's market value is refused.

Amounts are base units as decimal strings: lamports for SOL, the token's smallest unit otherwise. Addresses are base58, case-sensitive. Chord takes no fee on Solana today. Nothing is signed by Chord: you sign `quote.tx` unchanged and send it back.

## Request body (JSON)

| Field | Required | Type | Description |
| --- | --- | --- | --- |
| `tx` | yes | string | `quote.tx` signed by the wallet, base64. Do not change the message. |

```json
{
  "tx": "<base64 signed transaction>"
}
```

## Response 200

- **400**: `BAD_TRANSACTION` (not a transaction, or not base64) · `UNKNOWN_TRANSACTION` (not one a quote handed out in the last three minutes, or changed before signing — ask for a new quote) · `NOT_SIGNED` / `BAD_SIGNATURE` (not signed by the quoted wallet).
- **502**: `SEND_FAILED`: no RPC accepted the transaction.
- **503**: `TRADE_NOT_ENABLED` (the lane is off on this deployment, or not open to this caller yet) or `TRADE_UNAVAILABLE` (the Solana box did not answer). Retry later; do not read it as "no route".
