How this service works
Decision procedure for agents that must operate across blockchains: how to select tools, payment rails, and settlement paths per task when home-chain tooling is insufficient. Covers (1) task decomposition into chain-agnostic vs chain-bound subtasks, (2) capability inventory per candidate chain (tool availability, liquidity depth, bridge latency), (3) rail selection: x402 Base for micropayments, MPP/Tempo for sessionized spend, native rails where settlement finality matters, (4) the
Output
A prose decision procedure (the 'brief' field) guiding the agent through: (1) decomposing tasks into chain-agnostic vs chain-bound subtasks, (2) inventorying capabilities and liquidity depth per candidate chain, (3) selecting the appropriate payment rail (x402 Base, MPP/Tempo, or native), and (4) choosing a settlement path. Also returns metadata including the generation source (llm/reasoning/deterministic), ISO-8601 timestamp, topic, and service slug.
Example use cases
Multi-chain agent payment rail selection
“My agent needs to make a series of small payments across Ethereum and Base — walk me through the decision procedure for picking between x402 Base micropayments and native rails depending on finality requirements.”
Cross-chain task decomposition for DeFi bot
“I'm building a DeFi agent that operates on multiple chains. Can you give me the standard procedure for decomposing its tasks into chain-agnostic vs chain-bound subtasks and inventorying capabilities per chain?”
Bridge and settlement path selection
“My agent is moving assets cross-chain and I need to know how to evaluate bridge latency and liquidity depth across candidate chains to pick the right settlement path — what's the routing standard for that?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/cross-chain-agent-capability-selection-procedure?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent must dynamically decide how to route tasks, payments, or settlement across multiple blockchains and lacks a built-in cross-chain decision framework. It is especially useful when the agent's home-chain tooling is insufficient and it needs a structured procedure covering tool availability, liquidity, bridge latency, and rail selection. Prefer it over static documentation or single-chain payment guides when the agent must reason about tradeoffs across x402 Base, MPP/Tempo, and native rails in a single coherent framework.
Side effects
- Missing or invalid 'type' or 'method' fields returns a validation error
- Payment not provided results in a 402 Payment Required response before content is served
- Invalid topic override may result in a generic or misaligned procedure
- LLM-generated briefs may be non-deterministic across calls for the same topic
- Network or provider downtime returns a 5xx error with no procedure content
