SpiralStake

What it does

build_leverage_tx

POST /v1/build/leverage-tx — assembly, fast latency
Build the unsigned transaction to open a leveraged position — returns approvals, tx, and meta the user signs locally.

build_manage_tx

POST /v1/build/manage-tx — assembly, fast latency
Build the unsigned transaction to adjust or close an open position (actions: close, increase_leverage, add/remove_collateral, repay, borrow).

Workflows

• discover-best-yield — find the highest risk-adjusted leverage opportunity across strategies
• research-strategy — understand a single strategy's market, risk, and expected outcome before any commitment
• open-position — prepare an unsigned transaction to open a leveraged-yield or leveraged-long position
• manage-or-close — adjust an open position's leverage or collateral, or close it

What a call costs

Measured from the service's own 402 response on 2026-10-30T23:28:43Z — unpaid, first round only, nothing signed or settled. The exact amount is what a fixed call costs and is the price this page publishes; the quoted amount is always returned in the handshake, so a client never has to compute it.

This service offers no metered accept: the exact price is the whole price, which is why the table above stands alone.

These are exactly the seven chains the handshake answered for spiralstake; nothing above is a fallback or an estimate.

Start here

Two rounds, no account: send the request, read the 402, sign the amount it quotes, send it again. The first call is free to discover — a client learns the exact price before it pays anything.

curl -sS https://spiralstake.x402.press/v1/build/leverage-tx \
  -H 'content-type: application/json' \
  -d '{"model": "build_leverage_tx",
       "max_tokens": 1000,
       "messages": [{"role": "user", "content": "hi"}]}'
# 402 Payment-Required: base64url JSON, one accept per chain and per scheme
# (exact = the fixed price above; upto = the ceiling for that max_tokens)

The full endpoint list, parameters and manifest are on the service's own host: https://spiralstake.x402.press.
