Add InsumerAPI action provider for on-chain verification and trust profiles

[douglasborthwick-crypto]

Summary

Adds a walletless action provider for InsumerAPI — privacy-preserving on-chain wallet verification and trust profiling across 31 EVM chains and Solana.

• 5 actions: verify_wallet, get_wallet_trust_profile, get_batch_wallet_trust_profiles, validate_discount_code, list_compliance_templates
• Walletless: API-only provider (no wallet connection required), following the Messari/DefiLlama pattern
• Multi-chain: Supports 31 EVM chains + Solana via a single API — supportsNetwork() returns true
• Privacy-preserving: Returns ECDSA-signed boolean attestations, never raw wallet balances
• 21 tests, all passing. Lint and TypeScript clean.

WISHLIST Alignment

This addresses the WISHLIST item for trust/verification capabilities. Key differentiators vs open PRs #961 and #963:

	InsumerAPI (this PR)	#961 / #963
Chains	31 EVM + Solana	Base only
Wallet required	No (walletless API)	Yes (on-chain contract)
Privacy	Boolean-only, never exposes balances	On-chain, public
Condition types	token_balance, nft_ownership, EAS, Farcaster	Token-gating only
Trust profiles	17-check dimensional profiles	N/A
Compliance	Coinbase KYC, Gitcoin Passport templates	N/A

Actions

Action	Endpoint	Auth	Credits	Description
verify_wallet	POST /v1/attest	API key	1 (2 merkle)	Boolean attestation — does wallet meet conditions?
get_wallet_trust_profile	POST /v1/trust	API key	3 (6 merkle)	17-check trust profile across 4 dimensions
get_batch_wallet_trust_profiles	POST /v1/trust/batch	API key	3/wallet	Batch up to 10 wallets, 5-8x faster
validate_discount_code	GET /v1/codes/{code}	None	Free	Validate INSR-XXXXX discount code
list_compliance_templates	GET /v1/compliance/templates	None	Free	List EAS compliance templates

Sample Agent Prompts

• "Check if wallet 0xd8dA...96045 holds at least 1000 USDC on Ethereum"
• "Get the trust profile for vitalik.eth"
• "Compare trust profiles for these 5 wallets"
• "Does this wallet have Coinbase KYC verification on Base?"
• "What compliance templates are available?"

Files Changed

• typescript/agentkit/src/action-providers/insumer/ — 7 new files (provider, tests, schemas, types, constants, index, README)
• typescript/agentkit/src/action-providers/index.ts — added barrel export
• typescript/.changeset/warm-wallets-verify.md — changeset

Test plan

• All 21 unit tests pass (pnpm jest --testPathPattern=insumer)
• Lint passes (pnpm run lint)
• TypeScript compiles (tsc --noEmit)
• Format passes (pnpm run format)
• CI pipeline passes
