How this service works
Pay once for one routing decision: send the task and a bounded conversation packet, receive the x402 capability that fits it with its executable contract, argument schema and advertised terms. No provider call is made and no provider payment is authorized. Agent guide: https://tenjin.sh/llms.txt
Output
Returns the x402 capability that best fits the submitted task, including its executable contract (the signed x402 payment-ready descriptor), the argument schema (field names, types, and constraints expected by the capability), and the advertised terms (price, provider, scope). No provider is called and no payment is initiated or authorized.
Example use cases
Pre-payment capability scouting
“Before I authorize any payment, find me the best x402 capability that can answer detailed questions about climate policy research — I want to see the contract and schema first.”
Dynamic tool selection for agent pipeline
“My agent needs to answer a user question about cryptocurrency tax regulations — route it to the right x402 capability and give me back the argument schema and pricing terms so I can decide whether to proceed.”
Capability discovery for unfamiliar task type
“I'm not sure which x402 service handles sentiment analysis on financial news — can you find the best match for that task and show me what arguments it expects and what it advertises?”
Technical details
Endpoint
POSThttps://tenjin.sh/api/x402-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and preview the best x402 capability for a task before committing to a provider call or payment. Prefer it over static tool registries or hardcoded API lists when the task type is unknown at design time, when you want to inspect argument schemas and pricing terms before authorizing spend, or when building agentic pipelines that need cost-aware, routing-first architecture. Not appropriate when you already know exactly which capability to call.
Side effects
- No matching capability found for the task — returns empty or null capability
- Malformed conversation packet causes routing failure
- Task description too ambiguous to produce a confident routing decision
- Service unavailable or rate-limited at $0.001 USDC per call
- Returned capability terms may be stale if provider updated since last index
