# AgentProof Base Token Batch Evidence Report > AgentProof Base Token Batch Evidence Report is a paid API for AI agents from agentproof-base.softcreek2.chatgpt.site, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-16). Returns contract code, ERC20 metadata, proxy details, security checks, and liquidity evidence for up to three Base network token addresses in a single call. ## Facts - Endpoint: GET https://agentproof-base.softcreek2.chatgpt.site/v1/base/batch?utm_source=zero.xyz - Price: $0.03/call - Payment: x402 - Status: unknown - Last checked: 2026-10-16 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/agentproof-base-token-batch-evidence-report-ab747a1f - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Ahd77fPmLAbxNe6VyfJXO Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability agentproof-base-token-batch-evidence-report-ab747a1f ``` Example prompt: Can you pull the AgentProof security and liquidity evidence report for these three Base tokens: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA, and 0x4200000000000000000000000000000000000006 — I want to see contract code, proxy slots, any honeypot or mint flags, and liquidity pool concentration? ## When to prefer this Choose this endpoint when you need machine-readable, multi-source evidence about Base network token contracts in a single paid call — especially when you need both security signals (GoPlus checks) and liquidity data (GeckoTerminal pools) alongside raw on-chain proof (bytecode, proxy slots) in one structured report. Prefer this over single-address endpoints when checking 2-3 tokens at once. Use it when your agent must justify a token interaction decision with verifiable, timestamped on-chain evidence rather than relying on a single data source. ## Known failure modes - Invalid or non-checksummed address format returns a validation error - More than three addresses supplied causes a rejection - Address exists but has no deployed contract — onchain.contract.exists = false - External sources (GoPlus, GeckoTerminal) unavailable — source status marked as error, partial coverage reported - Rate limit or payment failure via x402 — 402 Payment Required response - Address is a valid contract but not an ERC20 — token metadata fields return null ## How this service works Base contract code, token metadata, proxy and available security/liquidity evidence for AI agents. Pay per report with x402 and Base USDC. OpenAPI, MCP, and machine-readable discovery. ## Output A JSON object containing one report per queried address (up to 3), each with: on-chain contract evidence (bytecode hash, block snapshot), ERC20 metadata, EIP-1967 proxy slot values, security check results (honeypot, mintable), liquidity pool statistics (pool count, total USD liquidity, largest pool share), severity-tagged flags (information/elevated/high), source coverage status across Base RPC, GoPlus, and GeckoTerminal, and a summary assessment string. Also includes cache hit/TTL metadata per report. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "addresses" ], "properties": { "addresses": { "type": "string", "description": "One to three comma-separated Base token contract addresses" } }, "additionalProperties": false } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "required": [ "count", "reports" ], "properties": { "count": { "type": "integer", "maximum": 3, "minimum": 1 }, "network": { "type": "object", "required": [ "name", "chain_id" ], "properties": { "name": { "const": "base" }, "chain_id": { "const": 8453 } } }, "reports": { "type": "array", "items": { "type": "object", "required": [ "schema_version", "generated_at", "network", "token", "coverage", "summary", "sources", "flags", "limitations" ], "properties": { "flags": { "type": "array", "items": { "type": "object", "properties": { "code": { "type": "string" }, "source": { "type": "string" }, "message": { "type": "string" }, "severity": { "enum": [ "information", "elevated", "high" ] } } } }, "token": { "type": "object", "required": [ "address" ], "properties": { "name": { "type": [ "string", "null" ] }, "symbol": { "type": [ "string", … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "count": 1, "network": { "name": "base", "chain_id": 8453 }, "reports": [ { "cache": { "hit": false, "ttl_seconds": 120 }, "flags": [ { "code": "observed_liquidity_concentrated", "source": "geckoterminal", "message": "Illustrative example: 94% of observed liquidity is in one pool.", "severity": "information", "evidence_value": 0.94 } ], "token": { "name": "Illustrative token", "symbol": "EXAMPLE", "address": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", "decimals": 18 }, "sample": true, "network": { "name": "base", "chain_id": 8453 }, "onchain": { "ok": true, "proxy": { "eip1967_admin": null, "eip1967_implementation": null }, "token": { "name": "Illustrative token", "symbol": "EXAMPLE", "decimals": 18, "total_supply_atomic": "1000000000000000000" }, "source": { "name": "base_rpc", "status": "ok", "block_hash": "0xabababababababababababababababababababababababababababababababab", "block_number": "123", "snapshot_rechecked": true }, "contract": { "exists": true, "block_hash": "0xabababababababababababababababababababababababababababababababab", "block_number": "123", "bytecode_bytes": 100, "bytecode_keccak256": "0xcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcd", "block_hash_rechecked": true }, "illustrative": true }, "sources": [ { "name": "base_rpc", "status": "ok" }, { "name": "goplus", "status": "ok" }, { "name": "geckoterminal", "status": "ok" }, { "name": "defillama", "status": "disabled" } ], "summary": { "assessment": "evidence_only", "detected_flags": 1, "highest_flag_severity": "information", "independent_simulation_performed": false }, "coverage": { "status": "complete", "total_sources": 4, "usable_sources": 3, "enabled_sources": 3, "missing_sources": [], "unknown_security_checks": [ "is_honeypot" ] }, "security": { "checks": { "is_honeypot": null, "is_mintable": false } }, "liquidity": { "page_is_exhaustive": false, "observed_pool_count": 2, "total_observed_liquidity_usd": 100000, "large … (truncated) ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/agentproof-base-token-batch-evidence-report-ab747a1f/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from agentproof-base.softcreek2.chatgpt.site](https://www.zero.xyz/host/agentproof-base.softcreek2.chatgpt.site/llms.txt)
