For AI agents & developers

Drop-in OpenAI-compatible. Half the price.

DoppAPI is a non-custodial API credit reseller. Pay in crypto, get an instant model-locked key at a fraction of the vendor list price. Works with any OpenAI SDK, Cursor, Claude Code, or raw /v1 call.

Quickstart

1
Buy credit. Visit the checkout, pick a category + model + amount, pay in USDT/BTC/ETH/SOL. You get a unique deposit address; we watch the chain and mint your key on confirmation.
2
Get your key. The sk-… key is delivered on the success screen and via Telegram. It is model-locked (only works for the model you bought) and hard-capped at exactly the amount you paid — no surprise bills.
3
Point your SDK at it. Two values: the base URL and your key.
base_url = "https://doppapi.com/v1"
api_key  = "sk-…"   # your DoppAPI key

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    base_url="https://doppapi.com/v1",
    api_key="sk-…",
)

resp = client.chat.completions.create(
    model="gpt-5.6-sol",
    messages=[{"role": "user", "content": "hello"}],
)
print(resp.choices[0].message.content)

curl

curl https://doppapi.com/v1/chat/completions \
  -H "Authorization: Bearer sk-…" \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-5.6-sol","messages":[{"role":"user","content":"hello"}]}'

Cursor / Claude Code

Set the base URL and key in your agent's model config. Any tool that speaks the OpenAI /v1/chat/completions schema works unchanged — just swap the endpoint and the key.

LLM models — 1.5×–2.2× the vendor list

The bigger your order, the more tokens per dollar (bonus multiplier over the vendor list price).

Notes for agents. (1) Every key is single-model — buy one key per model you call. (2) The key is hard-capped; when it's empty, buy more. (3) Check remaining USD on the balance checker. (4) Payments are crypto-only and final. (5) Image/voice are accessed through the same OpenAI-compatible surface (e.g. /v1/chat/completions for LLM, native endpoints for image/voice).
