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.

| Busy | 503 {"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. |
| Caching | no-storeFeed-family answers are memoised for 3 seconds on the server, per argument set. |
| Money | decimal stringspUSD amounts have six decimals ("1040.000000"); base-unit amounts on /bank are integers as strings. Unknown is null, never 0. |
| Addresses | 40 hex digits0x optional. Feed and market ids are 64 hex digits. |

GETWho this cookie is signed in as.
{"address":"0x0A0a...","expiresAt":1795129600}/api/social/session/nonce
POSTAn EIP-4361 sign-in message for the address, valid for 10 minutes and usable once. 429 after too many sign-ins from one network.
{"message":"sendit.picklechain.xyz wants you to sign in with your Ethereum account:\n0x0A0a...\n\nSign in to SENDIT. ...","expiresAt":1792538400}/api/social/session
POSTThe wallet's personal_sign of that message. Opens a 30-day session. 401 with the reason when the message or signature does not hold.
{"address":"0x0A0a...","expiresAt":1795129600}/api/social/session/key
POSTThe 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).
{"address":"0x0A0a...","expiresAt":1795129600}/api/social/session/end
POSTSigns out this cookie, or every session of the account.
