How this service works
Stores a forward pointer.
Output
A confirmation that the relay card (forward pointer) has been stored, associating the given seen_by agent identifier with the provided registry URL for future agent lookups and routing.
Example use cases
Agent discovery relay registration
“Register a relay card for the agent identified as 'summarizer-agent-3' with the registry URL https://registry.myfleet.io/agents so it shows up in routing tables.”
Tool registry forward pointer
“Save a forward pointer for 'tool-indexer-alpha' pointing to https://tools.internal.dev/registry — I need agents downstream to be able to look it up.”
Routing hint for agent orchestration
“Record a relay card that marks 'orchestrator-node-9' as the seen_by agent and points to https://hub.agentnet.io/v2/registry for forwarding purposes.”
Technical details
Endpoint
POSThttps://agent-gas-station.agent-gas-station.workers.dev/v1/RelayCard?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to register a forward pointer or relay card linking an agent identifier to a registry URL, enabling other agents in the network to discover or route to that registry later. Prefer this over manual registry entries when operating within the Agent Rest Stop / agent-gas-station ecosystem.
Side effects
- Missing or malformed registry_url causes rejection
- Invalid seen_by identifier format may result in error
- Duplicate relay card for the same agent/URL pair may be silently overwritten or rejected
- Payment failure (x402) if USDC not provided
- Network timeout from the workers.dev edge runtime
