Para desarrolladores / SENDIT

API HTTP de SENDIT

Dos servicios detrás del origen de SENDIT. dex-api es un índice de la cadena de solo lectura; social-api guarda sesiones, seguimientos, clanes y tesis. Ninguno de los dos es la cadena: cuando hay dinero en juego, lea los contratos.

URL base

  • dex-api: https://sendit.picklechain.xyz/api/...
  • social-api: https://sendit.picklechain.xyz/api/social/...
  • El manifiesto: https://sendit.picklechain.xyz/op-deployment/l2-perps.json

El proxy no envía ninguna cookie a dex-api. dex-api solo responde a GET y no pone ninguna cabecera CORS para otros orígenes: llámela desde un servidor o un bot, no desde una página de otro sitio.

Reglas comunes a todas las rutas

ReglaValor
MethodsGET onlyA trailing slash is ignored.
Errors400 {"error":"bad parameter"}A malformed parameter. An unknown path is 404 {"error":"not found"}. An index that is not ready is 503.
Busy503 {"error":"busy"}Feed, traders and copy routes run at most four reads at once and give up after a few seconds. Retry with a backoff.
Cachingno-storeFeed-family answers are memoised for 3 seconds on the server, per argument set.
Moneydecimal stringspUSD amounts have six decimals ("1040.000000"); base-unit amounts on /bank are integers as strings. Unknown is null, never 0.
Addresses40 hex digits0x optional. Feed and market ids are 64 hex digits.
Feed paginglimit 1-50, before = nextFeed cursors look like <block>.<txIndex>.<logIndex>.<tie>. Each query key may appear once, values at most 100 characters.

Perps

Params
none
Returns
{ engine, orders, vault, previous: [{ engine, orders, vault, version, bank }], bank, spotRouter, pusdExchange }

The manifest's perps addresses, lower-cased and renamed (perps -> engine, perpOrders -> orders, perpVault -> vault). bank and spotRouter appear only when a bank is deployed, pusdExchange only when one is named. Without a usable manifest every address is null.

Example
{"engine":"0x57c6...e971","orders":"0xcb62...2c84","vault":"0x20f4...f459","previous":[{"engine":"0x8452...0ef2","orders":"0xe728...dae8","vault":"0xc1bd...942d","version":1,"bank":null}],"bank":"0x3366...298f","spotRouter":"0xd651...a04b","pusdExchange":"0x07b5...385f"}
Params
none
Returns
{ markets: [{ feedId, symbol, maxLeverage, spreadBps, enabled, inverse, oiLong, oiShort, fundingRatePerHour, fundingSide, closedSpreadBps, engine, legacy, engines: [...] }] }

Every market in listing order, open interest summed over the engines. fundingSide is the side that pays (long, short or null). A market listed only on an old engine shows enabled false and legacy true.

Example
{"markets":[{"feedId":"0x...","symbol":"ETH/USD","maxLeverage":25,"spreadBps":2,"enabled":true,"inverse":false,"oiLong":"3000.000000","oiShort":"1000.000000","fundingRatePerHour":"0.00625%","fundingSide":"long","closedSpreadBps":10,"engine":"0x57c6...","legacy":false,"engines":[...]}]}
Params
trader (address, required); status open (default) or all; limit 1-500, default 50
Returns
{ positions: [{ positionId, trader, feedId, isLong, leverage, margin, size, notional, entryPrice, openFee, status, tp, sl, limitPrice, openedAt, closePrice, pnl, funding, closeFee, penalty, payout, badDebt, closedAt, engine, legacy }] }

A trader's positions, newest first. tp, sl and limitPrice are null when unset.

Example
{"positions":[{"positionId":"10000042","status":"liquidated","leverage":25,"margin":"49.375000","openFee":"0.625000","pnl":"-24.673911","penalty":"12.253260","payout":"11.981817","badDebt":"0.000000", "...": "..."}]}
Params
id (1 to 19 digits, required)
Returns
{ position: { ...position, closeReason, trades: [...] } }

One position with its last 10 trades. closeReason is closed, take-profit, stop-loss, limit, liquidated or null. An unknown id answers 404 {"error":"There is no such position."}.

Example
{"position":{"positionId":"10000042","closeReason":"liquidated","trades":[{"kind":"liquidation","netPnl":"-38.018183","penalty":"12.253260"}]}}

Returns
{ trades: [{ txHash, block, at, positionId, trader, feedId, kind, isLong, price, notional, fee, pricePnl, netPnl, penalty, engine, legacy }] }

Opens, closes and liquidations. kind is open, close or liquidation; pricePnl and penalty are null on opens. Without trader, copy accounts' trades are left out.

Example
{"trades":[{"kind":"close","fee":"0.500000","pricePnl":"0.097399","netPnl":"-0.902401","penalty":"0.000000"}]}

El inicio de sesión es EIP-4361 (SIWE): pida un mensaje con nonce, fírmelo con personal_sign y envíelo de vuelta. El mensaje vale durante 10 minutos y una sola vez. Con una clave de trading de SENDIT, un dispositivo inicia sesión sin la billetera:

Iniciar sesión con la clave de trading
const API = "https://sendit.picklechain.xyz/api/social";
const headers = { "Content-Type": "application/json", "X-Pepper-Social": "1" };

Fuera de un navegador, guarde el valor Set-Cookie de la última respuesta y devuélvalo como cabecera Cookie en las llamadas siguientes.

Params
none
Returns
{ address: null } or { address, expiresAt }

Who this cookie is signed in as.

Example
{"address":"0x0A0a...","expiresAt":1795129600}
Params
{ address }
Returns
{ message, expiresAt }

An EIP-4361 sign-in message for the address, valid for 10 minutes and usable once. 429 after too many sign-ins from one network.

Example
{"message":"sendit.picklechain.xyz wants you to sign in with your Ethereum account:\n0x0A0a...\n\nSign in to SENDIT. ...","expiresAt":1792538400}
Params
{ message, signature }
Returns
{ address, expiresAt } and Set-Cookie

The wallet's personal_sign of that message. Opens a 30-day session. 401 with the reason when the message or signature does not hold.

Example
{"address":"0x0A0a...","expiresAt":1795129600}
Params
{ account, key, message, signature }
Returns
{ address, expiresAt } and Set-Cookie

The same nonce message, issued for the ACCOUNT, signed by its trading key. The server checks the signature recovers to key and that bank.accountOf(key) is the account on the chain, then opens the same 30-day session: a new device signs in with no wallet prompt. 401 "This key is not the account's trading key", 409 when there is no bank, 503 when the chain could not be read (the nonce is kept; every other refusal spends it).

Example
{"address":"0x0A0a...","expiresAt":1795129600}
Params
{} or { everywhere: true }
Returns
{ address: null }

Signs out this cookie, or every session of the account.

Example
{"address":null}
Dos mensajes distintos

/session/key firma el mensaje de inicio de sesión ordinario. El mensaje "Unlock my SENDIT trading key" es otra cosa: la forma en que la aplicación deriva la clave, y nunca se envía a ningún servidor.
