llama-index-tools-insumer 0.3.1

LlamaIndex tool spec for InsumerAPI — wallet auth and condition-based access across 37 chains

LlamaIndex Tools Integration: InsumerAPI

Wallet auth and condition-based access for LlamaIndex agents. Across 37 chains — read → evaluate → sign, returning an ECDSA-signed boolean your agent can verify offline against the public JWKS. Boolean, not balance: the API never exposes wallet holdings, only a signed yes-or-no against the conditions you configure.

Part of InsumerAPI. No secrets. No identity-first. No static credentials.

Installation

pip install llama-index-tools-insumer

Quickstart

Get a key — no signup, no dashboard, no password. Two paths, both return an insr_live_... key instantly with 10 verification credits and 100 reads/day:

curl -X POST https://api.insumermodel.com/v1/keys/create \
    -H "Content-Type: application/json" \
    -d '{"email": "[e-mail]", "appName": "my-agent", "tier": "free"}'

Or enter your email on insumermodel.com — the key appears inline. Already have a key? Manage it at insumermodel.com/developers/account/.

Then use the tool spec in any LlamaIndex agent:

from llama_index.tools.insumer import InsumerToolSpec
from llama_index.agent.openai import OpenAIAgent

insumer = InsumerToolSpec(api_key="insr_live_...")

agent = OpenAIAgent.from_tools(
    insumer.to_tool_list(),
    verbose=True,
)

agent.chat(
    "Does wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 "
    "hold at least 100 USDC on Base?"
)

The four tools

attest_wallet

Run wallet attestation against 1–10 conditions. Returns an ECDSA-signed verdict per condition plus a condition hash for tamper detection.

Supported condition types:

• token_balance — ERC-20 / SPL / XRPL trust line / native BTC / TRC-20 / Stellar trustline / Sui-native ≥ threshold
• nft_ownership — ERC-721/ERC-1155/XRPL NFToken holding
• eas_attestation — EAS schema check (pass a template like coinbase_verified_account or a raw schemaId)
• farcaster_id — Farcaster ID registered on Optimism

insumer.attest_wallet(
    wallet="0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
    conditions=[
        {
            "type": "token_balance",
            "contractAddress": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
            "chainId": 8453,
            "threshold": 100,
            "decimals": 6,
            "label": "USDC on Base >= 100",
        },
    ],
)

Response shape:

{
    "ok": True,
    "data": {
        "attestation": {
            "id": "ATST-...",
            "pass": True,
            "results": [...],      # per-condition booleans + conditionHash
            "passCount": 1,
            "failCount": 0,
            "attestedAt": "2026-04-16T...",
            "expiresAt": "2026-04-16T...",  # +30 min
        },
        "sig": "...",              # ECDSA P-256 signature, base64
        "kid": "insumer-attest-v1",
    },
    "meta": {"creditsRemaining": ..., "creditsCharged": 1, ...},
}

Costs 1 credit per call (2 with proof="merkle" for EIP-1186 storage proofs).

get_trust_profile

Multi-dimensional wallet trust profile — stablecoins, governance, NFTs, staking (plus Solana, XRPL, Bitcoin, Tron, Stellar, Sui when those wallet addresses are supplied). Returns a signed summary showing which dimensions have activity, without exposing raw balances. Up to 49 checks across 27 chains.

insumer.get_trust_profile(
    wallet="0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
    solana_wallet="...",       # optional
    xrpl_wallet="r...",        # optional
    bitcoin_wallet="bc1q...",  # optional
    tron_wallet="T...",        # optional
    stellar_wallet="G...",     # optional
    sui_wallet="0x...",        # optional (64 hex chars)
)

Costs 3 credits per call (6 with proof="merkle").

list_compliance_templates

Discover pre-configured EAS compliance templates (Coinbase Verified Account, Coinbase Verified Country, Coinbase One, Gitcoin Passport, etc.). No API key required.

templates = insumer.list_compliance_templates()
# Use a template name directly in attest_wallet:
insumer.attest_wallet(
    wallet="0x...",
    conditions=[{"type": "eas_attestation", "template": "coinbase_verified_account"}],
)

get_jwks

Fetch the public JWKS used to sign attestation and trust responses. Enables offline verification of any result with a standard JWT/JOSE library. No API key required.

jwks = insumer.get_jwks()
# {
#     "keys": [
#         {"kty": "EC", "crv": "P-256", "x": "...", "y": "...",
#          "use": "sig", "alg": "ES256", "kid": "insumer-attest-v1"}
#     ]
# }

buy_api_key

Agentic commerce: let an agent purchase its own new API key on-chain with USDC or BTC. The transaction sender wallet becomes the registered identity. No email, no signup flow, no human in the loop. No API key required to call — the payment is the auth.

Pre-requisite: broadcast a USDC or BTC transfer to the platform wallet first, then submit the transaction hash here.

# After the agent broadcasts a 100 USDC transfer on Base to the platform wallet:
result = InsumerToolSpec().buy_api_key(
    tx_hash="0xabc...",
    chain_id=8453,            # Base; use "solana", "bitcoin", or "tron" for those chains
    app_name="my-agent",
    amount=100.0,              # USDC amount; not required for Bitcoin
)
new_key = result["data"]["key"]   # insr_live_... — shown once, save it

One key per wallet — if the sending wallet already has a self-serve key, the API returns 409 and asks you to top up the existing key via buy_credits instead.

buy_credits

Top up credits on an existing API key (the one you passed to InsumerToolSpec) with a USDC or BTC payment. Same pattern: broadcast the transfer, submit the tx_hash.

insumer.buy_credits(
    tx_hash="0xdef...",
    chain_id=8453,
    amount=100.0,
)

Supported chains

37 total:

• 31 EVM chains: Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB, XDC, Unichain, Linea, zkSync, Scroll, Blast, Mantle, Celo, Gnosis, Sonic, Moonbeam, and more
• Solana (mainnet)
• XRPL (mainnet) — native XRP plus trust-line tokens
• Bitcoin (mainnet) — native BTC only
• Tron — native TRX plus TRC-20 (USDT-TRC20)
• Stellar — native XLM plus classic trustline assets (USDC, BENJI, etc.)
• Sui — native SUI plus Sui-native tokens (USDC)

Positioning

Wallet auth is the primitive. Condition-based access is the category. Token gating is one use case. The API turns a programmable predicate over on-chain state into a short-lived cryptographic artifact any service can verify.

• No secrets: conditions are public, the signature binds the condition hash.
• No identity-first: a wallet address and a condition are enough.
• No static credentials: every response has an expiry and is re-checkable.
