How this service works
Agent-facing decision procedure for choosing which onchain data layer to pay for a given query. Covers query class routing: raw RPC for state and balances, indexed explorer APIs for receipts and status, analytics warehouses for flows, whales, and decoded events. Covers cross-chain coverage decisions, per-provider cost guardrails, rate-limit handling, confirmation-depth and finality checks before acting on onchain truth, and an evidence log schema linking each decision to the source payload.
Output
A paid response containing prose decision-procedure guidance (the 'brief' field), covering query class routing, provider selection, cross-chain coverage, cost guardrails, rate-limit handling, confirmation-depth checks, and an evidence log schema. Also includes metadata such as generation source (llm/reasoning/deterministic), topic, service slug, and ISO-8601 timestamp.
Example use cases
Routing raw RPC vs indexed explorer queries
“My agent needs to check both current wallet balances and historical transaction receipts across Ethereum and Optimism — walk me through which data layer to use for each query type and how to stay within cost guardrails.”
Whale flow and analytics provider selection
“I'm building an agent that tracks large token flows and decoded DeFi events on Base and Arbitrum — which analytics warehouse providers should it use and how should it route those queries compared to regular state lookups?”
Finality-safe decision evidence logging
“Before my agent acts on any onchain data, I want it to verify confirmation depth and log which provider and payload it used as evidence — can you give me the procedure for that, including how to handle cross-chain finality differences?”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/multi-chain-onchain-data-sourcing-and-provider-s?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs structured, payable decision-procedure guidance for routing onchain data queries across multiple chains and providers — especially when the agent must balance cost, rate limits, finality requirements, and cross-chain coverage in a single coherent workflow. Prefer this over raw provider documentation when you need opinionated, agent-ready routing logic with built-in evidence logging schema rather than raw API specs.
Side effects
- Payment not provided — returns 402 with payment details rather than the procedure
- Invalid or unsupported topic override — may return generic procedure without topic-specific guidance
- Rate limits on the upstream service — may return error or degraded response
- Malformed input schema — missing required 'type' or 'method' fields returns validation error
- Service unavailability — K-2SO host unreachable, returns network or 5xx error
