Python client for the AgentScore trust and reputation API

agentscore-py

Python client for the AgentScore trust and reputation API.

Install

pip install agentscore-py

Quick Start

from agentscore import AgentScore

client = AgentScore(api_key="as_live_...")

# Look up cached reputation (free)
rep = client.get_reputation("0x1234...")
print(rep["score"]["value"], rep["score"]["grade"])

# Filter to a specific chain
base_rep = client.get_reputation("0x1234...", chain="base")

# Identity gate with policy (paid)
gated = client.assess("0x1234...", policy={
    "require_kyc": True,
    "require_sanctions_clear": True,
    "min_age": 21,
})

if gated["decision"] == "deny":
    print(gated["decision_reasons"])  # ["kyc_required"]
    print(gated.get("verify_url"))    # URL for operator verification

# Check verification level
rep = client.get_reputation("0x1234...")
print(rep.get("verification_level"))  # "none" | "wallet_claimed" | "kyc_verified"

Credential-Based Identity

Agents without wallets can use operator credentials for identity:

result = client.assess(operator_token="opc_...")
print(result["decision"])  # "allow" | "deny"

Verification Sessions

Bootstrap identity for first-time agents. The success body carries structured next_steps (with action: "deliver_verify_url_and_poll") and a cross-merchant agent_memory hint. Poll responses carry next_steps.action from the typed NextStepsAction Literal (continue_polling, retry_merchant_request_with_operator_token, use_stored_operator_token, create_new_session, verification_failed, contact_support).

session = client.create_session()
print(session["verify_url"], session["poll_url"], session["poll_secret"])
print(session["next_steps"]["action"])  # "deliver_verify_url_and_poll"

status = client.poll_session(session["session_id"], session["poll_secret"])
if status["status"] == "verified":
    print(status["operator_token"])  # "opc_..." — use for future requests

# Optional pre-association: attach the session to a known wallet or refresh KYC
# for an existing operator credential.
client.create_session(address="0x...")
client.create_session(operator_token="opc_...")  # KYC refresh

Wallet resolution

assess() responses include resolved_operator and linked_wallets — all same-operator sibling wallets (claimed via SIWE or captured via prior associate_wallet). The list may mix EVM addresses (0x... lowercased) and Solana addresses (base58, case-preserved) for cross-chain operators; merchants doing wallet-signer-match checks should accept a payment signed by any address in the list, regardless of chain. The address parameter on assess() and get_reputation() accepts either format — network is auto-detected from the address shape.

Credential Management

cred = client.create_credential(label="my-agent", ttl_days=7)
print(cred["credential"])  # shown once

credentials = client.list_credentials()
client.revoke_credential(cred["id"])

Report an Agent's Wallet (Cross-Merchant Attribution)

After an agent authenticated via operator_token completes a payment, report the signer wallet so AgentScore can build a cross-merchant credential↔wallet profile. Fire-and-forget — first_seen is informational only. network is the key-derivation family: "evm" for any EVM chain (Base, Tempo, Ethereum, …) or "solana" for Solana.

client.associate_wallet(
    operator_token="opc_...",
    wallet_address=signer_from_payment,  # e.g. EIP-3009 `from` or Tempo MPP DID address
    network="evm",
    idempotency_key=payment_intent_id,  # optional — agent retries of the same payment no-op
)

Async

All methods have async variants prefixed with a:

async with AgentScore(api_key="as_live_...") as client:
    rep = await client.aget_reputation("0x1234...")
    result = await client.aassess("0x1234...", policy={"require_kyc": True})

    # Identity model methods
    session = await client.acreate_session()
    status = await client.apoll_session(session["session_id"], session["poll_secret"])
    cred = await client.acreate_credential(label="my-agent")
    await client.alist_credentials()
    await client.arevoke_credential(cred["id"])
    await client.aassociate_wallet(
        operator_token="opc_...",
        wallet_address="0x...",
        network="evm",
    )

Context Manager

with AgentScore(api_key="as_live_...") as client:
    rep = client.get_reputation("0x1234...")

Configuration

Parameter	Default	Description
api_key	None	API key from agentscore.sh
base_url	https://api.agentscore.sh	API base URL
timeout	10.0	Request timeout (seconds)
user_agent	None	Prepended to the default User-Agent as "{user_agent} (agentscore-py/{version})". Use to attribute API calls to your app.

AgentScoreError.status is a property aliasing .status_code so polyglot codebases can use the same attribute name regardless of which SDK raised the error.

Error Handling

from agentscore import AgentScore, AgentScoreError

try:
    rep = client.get_reputation("0xinvalid")
except AgentScoreError as e:
    print(e.code, e.status_code, str(e))

AgentScoreError.details carries the rest of the response body — verify_url, linked_wallets, claimed_operator, actual_signer, expected_signer, reasons, agent_memory — so callers can branch on granular denial codes without re-parsing:

try:
    client.assess("0xabc...", policy={"require_kyc": True})
except AgentScoreError as e:
    if e.code == "wallet_signer_mismatch":
        print("Re-sign from one of:", e.details.get("linked_wallets"))
    elif e.code == "token_expired":
        print("Verify at:", e.details.get("verify_url"))
