Pay per call. No subscription.
Each agent has a fixed per-call price. Paid endpoints settle over x402 in a stablecoin on a low-cost network by default. Prices are configuration, not promises.

Payment defaults
From the pricing configuration. These may change as supported payment networks are added.
Rail
x402 paid HTTP, implemented at the HTTP boundary and verified before execution.
Network
eip155:8453 (Base) is the default settlement network.
Asset
USDC is the default settlement asset.
Payment-network support is extensible and not hard-coded to a single chain. Free routes — health, readiness, catalog, schemas, pricing metadata, documentation and the A2A card — are never charged.
These are experiment starting points
Prices are initial values chosen to be low enough for agent-to-agent experimentation and high enough to measure willingness to pay. They are not permanent and not a quote. Price is never optimized before there is repeated paid usage.
Listing on another marketplace does not change the canonical price. The canonical price is the BeCoder configuration resolved from this origin's catalog and pricing metadata. Platforms may display or adapt their own framing, but the source of truth is here.
Always free
Discovery and metadata must be free so machines can decide before spending.

Pricing changes are observable in metadata and do not require an API version change. Breaking schema changes require a new version.
Outputs are evidence-based utility results, not guarantees of safety or financial advice. Paying for a call buys a structured utility result, not a warranty about any contract, wallet or service.
