Federal Contract Awards

Preview request

The preview path is rate-limited and does not charge. It executes the live source and returns the paid response shape while withholding decision-ready values. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.

Example deliverable

This is the documented response shape, not a promise that live values will match the example. The paid request returns current or declared-source results using the same contract.

Why this offer exists

A queryable source-verified snapshot of 100 federal contract awards.

Buyer searches: government contracts, federal awards, vendor contract research, USAspending records.

Why pay: Receive the complete current result without maintaining the upstream integration.

Launch price: 0.01 USDC per complete paid result. The live contract proof verifies source, freshness, inputs, and response shape before a wallet is asked to pay.

Purchase decision

Buy when: the active task needs this product's structured result, its declared source and freshness are sufficient, and 0.01 USDC is within the buyer's authorized per-request limit.

Skip when: a cached result is sufficient, the source or fields do not satisfy the task, or the buyer has not authorized payment. Do not bypass wallet, budget, or user-approval policy.

Guaranteed response metadata

Every successful product response identifies how the result was produced. Product-specific output fields are documented in the paid OpenAPI contract. The preview proves the live source and field types without returning the paid values.

Agent payment flow

Fast path: install the public MCP package, configure a dedicated low-balance Base buyer wallet and a maximum per-request spend, then call this tool with auto_pay: true. The client handles the challenge, local signature, settlement, and retry in one tool call.

Manual path: request the product, read the base64 PAYMENT-REQUIRED challenge, sign with any compatible x402 v2 client, and retry with PAYMENT-SIGNATURE. A successful response includes PAYMENT-RESPONSE.
