Bloopa SDK

LLM-gated micro-credit for AI agents on Algorand.

What Is Bloopa?

Bloopa is an on-chain AI agent credit protocol built on Algorand. It lets AI agents borrow microALGO to perform tasks — but only after a risk oracle evaluates the request and approves it.

The oracle applies four immutable criteria before any on-chain transaction is ever submitted. If the agent's task is too risky, too expensive, already indebted, or takes too long — the draw is denied and nothing hits the chain. No exceptions.

Quick Start

import os
from dotenv import load_dotenv
from bloopa_sdk import BloopaCreditAgent, BloopaCreditDenied

load_dotenv()

agent = BloopaCreditAgent(
    mnemonic_phrase=os.environ["AGENT_MNEMONIC"],
    app_id=int(os.environ["BLOOPA_APP_ID"]),   # 762466410 on testnet
)

try:
    result = agent.draw(
        amount_microalgo=50_000,
        task_description="Fetch the current ETH/USD price from CoinGecko and store it",
        expected_return_microalgo=80_000,
        estimated_task_rounds=120,
    )
    print(f"✅ Approved! txid={result['txid']}")
    print(f"   Repay {result['total_repayable']} microALGO when done.")

    # … run your task here …

    repay_result = agent.repay(result["total_repayable"])
    print(f"✅ Repaid: txid={repay_result['txid']}")

except BloopaCreditDenied as e:
    print(f"❌ Denied: {e.reason}")

Environment Variables

Variable	Required	Description
AGENT_MNEMONIC	Yes	25-word Algorand mnemonic for the agent wallet
BLOOPA_APP_ID	Yes	762466410 (Algorand Testnet)
VENICE_API_KEY	Default oracle	From api.venice.ai
ORACLE_PROVIDER	No	venice (default) or anthropic
ANTHROPIC_API_KEY	If ORACLE_PROVIDER=anthropic	Anthropic API key

Create a .env file in your project root:

AGENT_MNEMONIC=word1 word2 word3 ... word25
BLOOPA_APP_ID=762466410
VENICE_API_KEY=your-venice-key
ORACLE_PROVIDER=venice

The 4 Oracle Criteria

Every draw() passes through the risk oracle before any transaction is submitted. All four must pass:

#	Criterion	Condition
1	Profitable	expected_return > principal + interest
2	Time-bounded	estimated_task_rounds < 86,400 (~24 h)
3	Debt-free	outstanding_balance == 0
4	Low/medium risk	Task description evaluates to low or medium risk

Risk levels for criterion 4:

• low — deterministic, bounded (API calls, data fetches, calculations)
• medium — external dependencies with clear, verifiable success criteria
• high — speculative or unverifiable outcomes (denied)
• critical — financial speculation, unaudited contracts, irreversible actions (denied)

Tier System

Payment history builds reputation and unlocks better terms:

Tier	Name	Payments	Max Draw	Daily Cap	APR
0	Fresh	0+	0.1 ALGO	0.5 ALGO	24%
1	Trusted	10+	0.5 ALGO	2 ALGO	16%
2	Veteran	50+	2 ALGO	10 ALGO	9%
3	Elite	100+	5 ALGO	25 ALGO	4%

Full API Reference

BloopaCreditAgent

agent = BloopaCreditAgent(
    mnemonic_phrase: str,          # 25-word Algorand mnemonic
    app_id: int,                   # Bloopa contract app ID
    algod_url: str = "https://testnet-api.algonode.cloud",
    demo_mode: bool = True,        # False for production attestation
)

agent.draw(...) → dict

result = agent.draw(
    amount_microalgo: int,         # How much to borrow
    task_description: str,         # Plain-English task (oracle reads this)
    expected_return_microalgo: int,# Must exceed principal + interest
    estimated_task_rounds: int = 300,  # Must be < 86,400
)
# Returns:
# {
#   "txid": str,
#   "amount_microalgo": int,
#   "interest_microalgo": int,
#   "total_repayable": int,
#   "tier": int,
#   "tier_name": str,
#   "apr_bps": int,
#   "risk_summary": str,
# }

agent.repay(amount_microalgo) → dict

result = agent.repay(result["total_repayable"])
# Returns: {"txid": str, "repaid_microalgo": int}

agent.get_position() → dict

pos = agent.get_position()
# Returns:
# {
#   "stake_amount": int,
#   "payment_count": int,
#   "tier_max_draw": int,
#   "outstanding": int,
#   "is_defaulted": int,
#   "tier": int,
#   "apr_bps": int,
#   "daily_drawn": int,
#   "repay_by_round": int,
# }

agent.record_payment(amount_microalgo=1000) → int

Records an off-chain payment to increment payment count and upgrade tier.

RiskOracle (advanced)

Use directly if you want to separate oracle evaluation from the draw:

from bloopa_sdk import RiskOracle, RiskDecision, BloopaCreditDenied
from algosdk.v2client.algod import AlgodClient

oracle = RiskOracle(algod_client=AlgodClient("", "https://testnet-api.algonode.cloud"))

try:
    decision: RiskDecision = oracle.evaluate(
        agent_address="ALGO...",
        amount_microalgo=50_000,
        payment_count=21,
        outstanding_microalgo=0,
        task_description="Fetch ETH/USD from CoinGecko",
        expected_return_microalgo=80_000,
        estimated_task_rounds=120,
    )
    print(decision.attestation_hash.hex())   # 32-byte hash for draw()
except BloopaCreditDenied as e:
    print(e.reason)

Switching to the Anthropic Oracle

export ORACLE_PROVIDER=anthropic
export ANTHROPIC_API_KEY=sk-ant-...
pip install bloopa-sdk[anthropic]

Model: claude-haiku-4-5-20251001. The returned RiskDecision is identical regardless of provider.

Exceptions

from bloopa_sdk import BloopaCreditDenied, BloopaCreditError

try:
    result = agent.draw(...)
except BloopaCreditDenied as e:
    # Oracle denied the request (4 criteria). No tx was submitted.
    print(e.reason)           # "Criterion 4 failed: task risk level is 'critical'..."
    print(e.criteria_results) # Full dict from CriteriaEvaluation.model_dump()
except BloopaCreditError as e:
    # API or chain failure (algod unreachable, bad API key, etc.)
    print(str(e))

---

Demo Mode vs Production

By default demo_mode=True: the attestation hash sent to the contract is bytes(32) (32 zero bytes), and the testnet contract skips on-chain verification. This is safe for testnet.

For production deployments where the contract verifies the attestation hash:

agent = BloopaCreditAgent(
    mnemonic_phrase=...,
    app_id=...,
    demo_mode=False,   # Real SHA-256 hash computed and verified on-chain
)
